Connecting a two-layer switch - diagram and all connections nuances. Connect a two-block light switch at home Connection diagram 2 chandeliers on a two-block switch

There is a significant amount of use of double switches. They are used for chandeliers when control and adjustment of the brightness of the lighting is required. They are relevant for separate bathrooms. To illuminate entry in private households. If there is no specific preparation, then the diagram of connecting a two-block switch may cause some difficulties. But using the installation instructions and useful recommendations, even the newcomer can cope with a similar installation.

A two-lying device is an important component of any modern interior.

Before you know how to connect a two-block light switch, let's find out more information about its device. The mechanism includes plastic housing, input and output terminals, two keys, and some models have a light indicator.

If you correctly connect the connection, then you can enable electricity or stop it.

The design has some advantages:

the ability to disconnect and include whole groups of lamps;
savings on the cable, since it does not need to pull two wires, as for single devices;
allows you to adjust lighting with a large number of lamps in the chandelier;
it is used for premises with high levels of humidity;
it does not require special care;
easy installation.

Before learning the instructions, how to connect the chandelier to the two-lying switch, you need to prepare all the necessary tools. This includes a plastic form, indicator and figured screwdriver, crimp tools, as well as a construction knife.

Competent selection of electrical equipment guarantees safety, reliability and aesthetics of use. Let's figure out in existing brands and models.

Preparation of wires for the correct installation

Preliminary billet cables depends on the type of connected equipment. In such mechanisms, ready-made highways are provided. To change the components, you will need to disassemble the base of the lamp. The box device assumes three cables. Their total length should not be more than 10 cm. The ends of the cables must be cleared of isolation, and then connect to specific terminals. A phase is connected to the terminal with the designation L. Connecting other wires depends on which keys will be used.

Helpful information! If you have a modular mechanism, it is important to ensure the power of each component. In this case, you can use the jumper.

When choosing a diagram of connecting a two-layer switch, you need to take into account that the installation and fasteners of the wires are made using screw type clips or self-consuming terminals. The first option involves laying a bare wire between the plates. With this method, periodic tightening of the screw is required.

By connecting the two-layout mechanism, it must be remembered that zero is connected directly, and the phase is interrupted when passing through the device.

The connection process is done like this.

Picture	Stages
	First, the power supply is turned off in the shield, and then the lack of voltage is checked using the indicator.
	A cup is installed in the socket, and the wires from the mounting box are pulled through it. Lightweight veins by 10 mm is performed using boumbors.
	The wire with phase is connected to the terminal, and the remaining wiring into the terminals. Each element corresponds to a specific key. The phase wire often has white.
	If a certain procedure for inclusion of various groups of lighting is needed, then after checking, if necessary, the wires in the terminals are changing.
	Mount the housing of the switch and secure it with screws. Then the location of the design level is checked.
	The framework of the frame and the plastic keys is made.

Finally, the lighting source is connected and the correctness of the switch is tested. Two-core wires are carried out to the mounting box.

Options for connecting a two-block switcher to two light bulbs

There is a diagram of connecting a two-layer switch to two light bulbs. It includes such steps:

de-energization of the room;
it is important to identify outgoing wiring. There must be cables that depart on zero, grounding and phase. To better figure them out, you should look at the shield;
the installation of light sources and wires to the switch are carried out;
switches are considered attached, as they are attached to the walls. At the same time there should be a hole in the wall, where the wires are displayed. The connection is made using a soldering iron or a twist.

After summing up all the parts, the switch is fixed on the surface of the wall. It is worth aware of the different techniques for connecting wires in the distribution box. Pressing is relevant for industrial premises. Special equipment is used for soldering. The easiest and most reliable ways should include the use of self-apparatus compounds. It is also worth it to have an idea of \u200b\u200bthe method of connecting a two-layer switch for hidden wiring.

Features of the diagram of connecting a two-block passage switch

Connecting the passage switch is often used. Such devices are used for long corridors, large passing rooms and stairs. In spacious rooms, it is often difficult to choose a suitable place to set the switch, so it is difficult to do without passing device. The socket is mounted anywhere, but the adjustment should be available from any places. At the same time, it is necessary to mount additional elements at the beginning and at the end of the room.

Connecting the passage mechanism has some features. Three contacts are required for competent connection. A phase is supplied to a separate contact, and zero is carried out to the lamp. Two other contacts are used to connect passage devices.

Connecting a transient or cross-block switch is easier to perform if you follow some recommendations:

when installing, check individual cables;
phase is one wire, it can be checked using an indicator screwdriver;
before fastening it is important to check the performance of the structure.

What problems may be

The malfunction of the installed device happens from different reasons. For example, one of the keys can skip a certain light group, or all the lamps are turned on simultaneously. This suggests that the distribution of lighting devices on the keys does not work. Also, the switch may not work at all. Such problems occur when the wires are incorrectly connected or when they are connected in incorrect order.

Remember that when booking, the wires often do not comply with the color marking standards, so carry out additional check. Using the indicator, contact all wires.

Simple tips will help avoid many problems. Do not forget to turn off electricity before starting any work with electricity. Act in accordance with the instructions and correctly label the conductors.

Useful Tips for the proper use of the connection circuit of the two-block passage switch

Many people are interested in the issue of connecting the two-block passage of the switch independently, without the call of electricians. This is not so difficult to do, especially having a detailed connection schemes and a detailed description of each step.

Distinctive features of the switch of two-block

A switch that is designed to control separate light sources is called two-block. Such sources include both various layout of sofits and chandeliers with separate control. Typically, circuits with 2-key switches are actively used in apartments and offices where you need to control two lighting lines. In the corridors, bathrooms and passing rooms there are no sharp necessity, so there is the most ordinary classroom passage switch.

On such switches there are special arrows that are needed to specify the ON / OFF position.

If the wiring is made in such a way that there are several equivalent control points in the room, the position "enabled" or "off" cannot be determined unambiguously.

This is the main difference between such systems from ordinary one-blocks from the user's point of view.

From a technical point of view, this switch is two classmates that have a common case and function on the principle of "crossing" contacts. In all two-block control systems, 6 contacts are used: 2 are input, and 4 - output.

Connection diagram of a two-block passage switch

In solving the issue of connecting the two-block passing switches, the most useful will first understand the simplicity of the installation of two classmate switches.

How to connect two single-wave passing switches

To understand the mechanism of operation of a more complex system, you must first figure it out with its base element.

The diagram includes such elements: a distribution box, a pair of passing unlock switches, any lamp and wires. This kind of a two-block passage switching circuit is used to provide the ability to control the light of two places.

As can be seen on the drawing provided, "Earth" passes from the distribution electrical box directly to the light bulb. The network phase is connected to the general clamp of the first switch. Two output contacts of this switch are connected to the same elements of the second. It is logically understandable that from the second switch the wire goes back to the box and already from there the voltage enters the lamp.

Installation in practice is simple enough: first the switches are placed in their boxes.

Then the light bulbs are installed. And they are connected together in parallel and only one two-core cable comes out.

A distribution box is placed on the prepared predetermined place, which connects contacts and from the switch, and from the lamps, as well as the "Earth".

Enable lighting from two places - control circuit

But now you can talk about a more complex system. Here is a circuit of connecting the passage switch from 2 beds:

You probably have already guessed that such a scheme is nothing more than a double scheme for connecting a single-color switch to control from two places. In fact, each key is an independent switch. Everything is simple here, so it makes no sense to spread much. The situation with the connection of at least three two-lying passing switches looks much more interesting.

The preliminary calculation of the estimated power for household needs helps to carry out the correct and safe installation of wiring. When calculating the cable cross section for power before the final choice of the desired section, it is necessary to take into account the consumed of the electricity groups and the maximum current value for each segment.

Increase the reliability of consumer power supply helps the correct connection of wires in the distribution unit. Here you can read about the different methods of connecting the cable, both homogeneous and from different metals, in the distribution box.

There may be several difficulties that are easy to install from the schemes presented above:

the middle switch has more wires and a completely different connection scheme;
the design of this switch is somewhat different from the extreme.

It is clear that both of these factors do not contribute to the simplification of the scheme, but, on the contrary, create a huge amount of wires.

This is the key disadvantage: more wires - more materials, more materials - more work - more costs.

Despite the unpopularity of this scheme, it is still worth considering it.

Features of lighting control with three places

Due to the low popularity of such a scheme, it is rather difficult to find cross-two-belfry switching switches that occupy a middle place in the scheme. Usually, such a problem is solved by installing an additional pair of classroom switches in one frame. The diagram is shown in Figure:

As you can see, this scheme is characterized by the presence of another parallel scheme of a single-wave passage switch. Thus, two combined control circuits are used to control from three places.

Installation of the circuit breaker circuit breaker

On the installation of classmatic circuits we talked above. For two-blocks, everything is somewhat different: there is no junction box, so the mechanism will be as follows:

first, the switches themselves are installed in special boxes, the findings of which are left sufficiently long;
after that, lamps are installed, the contacts of which should also be long;
connecting in accordance with the scheme.

As you can see any complex details in the installation of two and three passing two-block switches there are no. Everything is quite simple, and having a scheme and a mechanism of installation with work, even a non-professional electrician will cope with work.

How to connect the switch with two keys? Detailed connection scheme

Two-block models are widespread and installed almost on all buildings, household and industrial structures. Switches of this species provide light control from one place in different rooms. Include light on chandeliers with two lamp groups or two groups of lamps in large rooms. Not so complicated, but in order to collect the scheme and competently perform the installation of all items, you need to familiarize yourself with the details of this process.

Constructive features of a two-block switch

Like all products, two-block divided by the following features:

Two-block switch for hidden wiring

For what type of wiring is used, external or hidden, the difference between the design of the case and installation methods. For internal wiring, the housing has a mechanism of sliding slats, locking the switch inside the wall hole. The nest under the fastenings of products on the walls is made using perforators with a crown with winners or diamond cutters. First, plastic or metallic pealation of the cylindrical shape is installed, then the design of the housing. The rotation of the sprinkling mechanism screws are retractable, they are based on opposite edges of the planting hole, hard locking the case of the light switch of the hidden wiring to the wall. Products for open wiring are more often used for buildings with wooden walls or in collection-shield structures. The body is fastened with self-drawing to the wall of the wall.

Two-block light switches differ from contacts of contacts, two types of contact design are used. Screw, bare end of the wire is clamped with a screw between two metal plates. A very reliable way, but has one significant disadvantage, with a weakly clamped wire or incorrectly selected cross section of wires, contacts are heated.

This leads to a weakening of the clamping force, it is required to periodically pull the screws. Otherwise, there will be a complete loss of contact or wiring ignition, other plastic elements of the light switch. In the clamping structure, the end of the wire is fixed by the plate on which the spring constantly cries, providing a stable contact.

According to the material from which the housing is made

Light switches can be divided by the material from which the housing, plastic or ceramic is made. They necessarily make a marking of the permissible value of the current, power, volts. Ceramic products are well discharged heat, designed to be installed in the high load circuit 10a, 220V, power up to 2300W. Plastic enclosures are calculated for smaller currents of 3-6a.

Criteria for selecting a two-pole switch and other schema elements

Before choosing a suitable sample and collect a circuit, decide on the network parameters, which will be wiring, hidden or external. How much power will be consumed lighting devices, determine the required cross-section of the wires. For chandeliers, where there are two groups of lamps, one by 100W and three to 40 W, the power consumed will be p \u003d 220W. Calculate the current:

With such a load, it will be enough to install a two-block element with a plastic body on 3a, the cross-section of the wires of 0.75 mm / sq.

When you need to illuminate the gym, where two groups of eight lamps, on each lamp 3 daylight lamps of 80 watts. Power of one group P \u003d (80 x 3 x 8) \u003d 1920 W.

I \u003d P / U \u003d 1920W. / 220V \u003d 8.7 A.

For such a lighting circuit, you will need to install a two-block switch in a ceramic case with a current load of 10a. The cross section of the wire is selected by predetermined tables, they are in PUE (rules of electrical installations).

To save on electricity payments, our readers advise "ELECTRIC ENERGY ENERGY SAVING BOX". Monthly payments will become 30-50% less than before the use of the economy. It removes the reactive component from the network, as a result of which the load is reduced and, as a result, consumption current. Electrical appliances consume less electricity, the costs of its payment are reduced.

As practice shows, for the posting of the lighting in most cases, a three-core cable with copper wires is used 0.75 - 1.5 sq. M. / mm.

The most accessible and frequently used cable brands:

VG is three copper wires with polyvinyl chloride insulation of three colors and in a common insulating sheath;

PUNP - the fixed wire is flat, comfortable for hidden wiring without a lift, is attached to the walls of the brackets and is covered with plaster. Double isolation, wires are coated with a polyvinyl chloride layer, a common PVC plastic shell.

Device and principle of operation of a two-block switch

This is a mechanical design, with three contacts, one fixed (general) and two independent of each other. When you click on the appropriate keys, the brass plates turn into a common contact, a closure chain. Two-block designs have 6 work positions:

2 positions of the first key, turned on or off;
2 positions of the second key, turned on or off;
2 positions of both keys are turned on or off.

Thus, the lighting groups are controlled connected to the two-lying switch. They can work simultaneously when you turn on both keys or separately when one of them is turned on.

Connection diagram Two-block switches

When connected to one device lighting (chandelier with two groups of lamps), three cables with three copper wires start up in the junction box:

from the distribution shield;
from the two-lying switch;
from the chandelier, a beam or other lamp with two groups of bulbs.

Connection diagram Two-block switches

The blue wire is directly connected to the zero chandelier contact. Red comes to a fixed (total) contact of the switch, the yellow-green wire is connected to the grounding terminal of the lighting device. The two remaining movable (weekends) of contact, through the box are connected to the free terminals of the lamps. If two lamps are connected for different rooms, a two-button switcher controls the light, four cables are added to the box:

from the distribution shield;
from the switch;
two from different lamps.

The connection principle does not change, the yellow-green wires of grounding of the housings are connected in one contact. Further, it goes on the grounding branch of the distribution shield. Unused wires can be insulated and left as reserve.

Please note that the requirements of the rules for the isolation color and wire assignment can be performed completely only on two sections of the circuit. Cable from the switchboard to the box and from the lighting device before the junction box. From the output contacts from the shift point to the box, these requirements are imparted, it is allowed to use wires of any color. At the same time it is necessary to be very attentive, especially with hidden wiring.

To check, use a multimeter in transversion mode or other measuring instruments. Unlocks in the lighting chain always phase (red wire). This is done primarily for safety when repairing lamps or new installation. When the protective automaton is turned on on the distribution shield, the indicator screwdriver is easy to control the presence of a phase. Then, on the lighting devices, you can check the phase, making sure the two-pole switch is in good operation.

Wall mounting features

In reinforced concrete and brick buildings, it is recommended for lighting the hidden wiring, junction boxes and switches to put in advance prepared shoes. Podozhetti is better to insert plastic with holes for fastening screws and fix them with a gypsum solution.

For reliable attachment, buy two-lying products with a design that provides two ways to fastening:

The sliding mechanism, whose planks rest in the opposite walls of the hole. Do not drag the spacer bolts, the ceramic circuit breaker body can crack.
On the perimeter of the housing, a galvanized plate was built with standardly located holes, through them the switch can be screwed to the submersion and the wall using plastic dowels and self-tapping screws.

The enshrined body on the spacer mechanism and the self-tapping screw will never fall out of the wall.

Two-block switches for external wiring are simply screwed to the wall screws, and junction boxes are also attached. Wires between them are desirable to lay in plastic cables.

Knowing structural features, products for hidden and external wiring, how the diagram of connecting a two-block switch, the principles of the control circuit, it will be easier for you to make the right choice of the desired items. Knowledge How to connect a two-block switch make it possible to put all the elements of the scheme, independently not referring to the services of electricians.

Connecting a two-layer switch: Schemes, Tips, Instructions

Two-block switch is a very important element for adjusting the degree of lighting of an apartment or a private house. Light bulbs can be located in groups or one, the light on them can be fed by a separate key.

Very often, during the repair during the new posting, the question arises, how nevertheless connect a two-block switch to provide several lighting modes. How to connect a two-layer switch with regard to the necessary security measures - read Next!

Construction and principle of the two-block switch operation

The design of the two-layout switch is quite simple. It consists of:

Two keys (moving up and down part).

Cases (shell), which is removed before starting work with electricity.

Terminals (those places to which voltage or current supply).

Rarely the Third Element - Terminals - can be replaced in the design on the screw clamps. The difference is that the first long and reliably hold the wire, and the second do the same, but not by clamping the wire, but spinning it, so the first option is connected easier and exploited longer. Also in the design there may be an additional backlight - a dimmer located on each key. About connecting a two-block switch with dimmers read just below.

Inside the two-block switch without highlighting there are two wires that are parallel to each other and the input for the phase. Each of the terminals, suitable to the keys, maybe independently of the other erode or put a contact, as a result of which one lamp is turned on (part of the lamps), the second lamp, or all the lamps together

Note! If you need to give a current not one, but immediately into several light bulbs. It is necessary to use stranded wires. It just allows you to make a two-block model of the switch.

The principle of the operation of the switch lies in the variability of the degree of lighting:

Only one key can be enabled so that one light bulb (or the first group of lamps) caught fire.

It is possible to turn on the second key - the lighting will change, since some parts of the room will be clearly visible, while others are a bit darkened.

The third option is the inclusion of "on the full coil" - both keys are in the "On" position - then the room receives maximum lighting.

By the way, some two-block switches consist of two isolated single-color devices from each other. In this case, it is customary called by modular.

In addition to the external component, such a device can also perform the functions of energy saving and creating a variety of atmosphere. And another two-block switches increase safety, since when they are installed, the number of points with electrical voltage decreases.

Before starting the preparation of the switch, we suggest familiarize yourself with the two-layout circuit breaker below:

Preparatory work

During work with an electrician, it is necessary to observe maximum accuracy and caution, so all materials and tools needed to work should be prepared and purchased in advance:

screwdriver flat and cross;
pliers;
boxes;
insulating tape;
a good construction knife with a sharp blade (for stripping the ends of the wires);
for crimping it is more convenient to use a special tool - a crimp (it is not mandatory if the wires are not multiply);
switch;
wires.

Attention! It is very important before starting work to turn off the voltage on the network!

Extremely important (especially for non-professional) in advance and correctly depict the scheme for connecting and pave the wiring.

The scheme should include such three wires:

Ground wire (is displayed on the light source, denotes the diagram as "0" or using an arrow indicating down).

Neutral wire (Also is displayed on the light source, denoted by the letter "n").

Phase - The wire under voltage, which, when turned on, must provide light bulbs with power (terminals for phase wire are denoted by the Latin letter "L").

We can carry out the wiring of one of two possible ways: open or closed. For the first you will need additional materials - corrugated logs or shoes, for the second - you need to come in the walls in the walls.

Note that the installation of wiring is made before plastering walls and ceiling. This means that only after laying all wires and sufficient isolation, you can start finishing work.

To do a small deepening, the circuit breaker will also have to use the chisel and hammer (this is not necessary if the switch will be installed on the old place).

Connecting a two-layer switch

Before you do the connection, you must first clean the ends of the wires by 1-1.5 centimeters to provide good contact with the terminals. If the wires are powerful, stranded - at this stage you need to pay their ends.

Three wires should be suitable for the switch with two keys. One of them is the input - phase, and the other two weekends, which will supply the voltage directly to the lamp itself.

The neutral wire and grounding, as already mentioned, are joined directly to the light source (to the light bulbs, more precisely to their contacts).

After that, you need to find the phase wire and the entrance to it (it, in contrast to the exits, one). Look at the switch pre-released from the upper casing. It should be drawn at least one arrow. She usually indicates from where and where the phase will go. Near the base of the arrow of the wire phase must be input.

As a rule, in such switches, the terminal for the phase input is indicated by the "L" symbol, in turn, the terminals for the output cables are indicated by the characters in the form of the arrows.

To accurately find a phase, use a special device. And if it is not, it is possible to determine this experimentally by connecting the chandelier or lamp for a while.

So, you need to connect the pliers in pairwise (not at the same time!) One wire with two others. That is, you choose one wire and bring it first to one of the remaining, then to another. This wire, from which one, then, the other group of lamps (lamps) will light up, and is a phase.

When the phase is found, it can be connected to the input of the switch (this is the first wire that goes to the switch), and two other wires - to two terminals-outputs, respectively (this is the second and third wires that go to the switch). Next, it will also be left to exhibit dangerous places on the wires and insert the design into the conversion, which should be screwed into place in advance for this prepared.

After you can only set the fittings and you can check the device in operation.

What would be better to understand the connection scheme, we suggest watching the video below, in which it is described in detail and on the examples shows a diagram of connecting a two-layer switch:

Connecting a two-block backlit switch

The diagram described above, the backlit switch makes small additions. Namely: Two more wiring appears (in order for the red light, a red indicator is burned on each of the two keys - it's easier to search for a switch in the dark).

So, these additional wires go from mini-indicators located on the keys. Next, one of them must be attached to the phase, which goes from above, and the second that is from below to the wire, which goes to one of the two lamps (lamp groups).

Useful advice

Distribute the desired (sufficient) section in advance and the length of the wires depending on the power of light sources. The section cannot be less than one and a half square millimeters.

Recommended besides the distribution box, also purchase an additional protective device that will protect against short circuits and overloads in the power grid.

Select terminal switches, and not with screwing screws, since the first connection option is more durable and durable: screws will need to twist after a while.

You can adjust the illumination using a single block device! But for this, additional equipment is acquired and installed - the so-called dimmer.

If you set a similar design to illuminate a bathroom or other wet place, in no case mount the indoor switch.

Note: If the switch is modular, then there is always one next to the input terminal. These two terminals must be connected to a separate wire.

All connections and attachments are strictly forbidden to spend out of special junction boxes. And in the case of complicated surrounding conditions, it is necessary to make additional protection (for example, water, humidity, other solid and liquid substances.

If you install a switch, for example, for a toilet, then one of the keys may include the light in this room, and the other is an exhaust.

Connect the switch that regulates the light with two keys is easy if you accurately follow the data above the instructions. Read first all instructions and useful tips so that you do not miss anything, then everything will work out!

Connecting two-layer switches to the chandelier to two lamps is somewhat more complicated than the recently considered. But since in the comments, this topic rises quite often - we will make a clear clarity and post a detailed instruction with the scheme. Let's start with the fact that we have a chandelier or wall lamp with two light bulbs, and it is necessary that each of these lamps is independently turned on with a separate button.

Let's look at the principal scheme

There are only a phase conductor to the switch, or rather: Phase power inlet 220 V, the phase wire that feeds the first light bulb, the phase wire that feeds the second light bulb.

Neutral and protective wires are connected together inside the box using electrical connectors (), with the exception of the circuit breaker.

For the proper operation of the scheme, you need a 4-wire cable that comes from the box to the lamp. If the electric wiring is duct (no protection, TN-C system), three wires. In this case, connect the neutral conductor to the protective connector in the lamp, and it is connected by a short wire with a neutral terminal.

It works so that by pressing the key on the left, the electrical potential from the power cord connected to terminal number 1 is transmitted to terminal No. 2 and from there to the top lamp. When you press the right key, the potential of terminal number 1 is transmitted to Terminem No. 3 and from there the power goes to the lower lights.

By switching any keys to close the electrical circuit, because on the one hand we supply the potential, and on the other hand, the neutral wire is constantly connected to the lamps (the image is animated - observed).

Remember that any 220V electrical voltage work can be dangerous. Before starting work, make sure that the voltage is turned off, for example, using neon tester. Remove fuses or disconnect the current fuses! Failure to comply with this instruction can lead to electric shock, which has already happened more than once with careless people.

Go to a practical connection

Let's expand the topic answering the question: what if the chandelier has more light bulbs?

Nothing special will happen, the scheme remains the same. Inside the chandelier, the bulbs are divided into two groups (arbitrarily), and one wire is displayed for each bulb group. For example, in chandelier with 5 light bulbs, we will make 4 outputs on the electrical block.

Neutral will become common for all lamps, and 2 phase will be supplied by 2 + 3 or 4 + 1 lamps.

Connect the protective wire to the last terminal connected to the lamp housing. This clamp can be placed separately, directly on the lamp housing, but it may not be if the chandelier housing is made of a toxconducting material, such as plastic.

As a result, we light 2 lamps with one button, the other - 3 light bulbs, and pressing both keys to get the light from all 5 light bulbs.

How it looks like the switch side - see photo:

This switch has 4 pairs of contacts.

In one of the two holes in the upper left corner, insert the source phase wire 220 V.
For a pair of contacts in the lower left corner, we connect one of the phase conductors to the lamp.
To the pair of terminals in the lower right corner we connect the second phase conductor leading to the lamp.

How to find out where is the terminal? It is always indicated on the switch housing.

Here he is marked by arrows. In the picture on the left you see the arrow indicating the inner part of the switch (upper left corner), symbolizing the introduction of the potential of the network or power cord. In the figure on the right (the left right side of the switch), the arrow indicates the direction of the current from the switch and the power transition to the lamp.

How to control two independent lamps

The control circuit diagram of two independent lamps will look like this:

Here we replace one 4-wire cable with two wires, the minimum must be 3-core (they can be 4 wired for future modernization, but only 3 of them will be used at the moment).

Two independent switch 2 lamps

This solution is quite rare, although dual switches often have 4 terminals. That is, sometimes a double switch consists of two independent individual switches. Or simply you have 2 single keys switches. Then simply share the switch that in the diagram for two halves, each of which is placed where it is necessary in the room.

This allows you to connect each of the lamps to your power source.

We are confident that after studying this article, the double switch connect will be the same simple matter,

Connecting a two-layer switch: Preparatory work

It is worth noting that before connecting the light switch, which is double, you need to pave the wiring. If the house is only built and the wiring is carried out in it, there are no difficulties. The wiring itself is installed even before the plaster is applied.

After that, you need to connect the switch and lamps to the wiring. The gasket of all wires is carried out according to the scheme (see below).

The two-block switch is designed to turn on and off from one place of two electrical appliances or control of individual sections of one device.

Most often, these switches are used to switch the operating modes of the chandelier: each of the two keys includes one of two groups of lamps, and when both keys are turned on completely the entire chandelier.

Using such a switch, you can control the illumination of the room. Also, the use of a light switch with two keys is useful to enable the lighting of a separate bathroom and toilet.

The circuit of connecting the passage switch to two lamps is not really so difficult, as it may seem at first glance. If it is a private house, connect a double light switch will be convenient for the lighting of the street at exit. If you can use the lighting device with a two-block switch on the balcony, there is also appropriate.

In each of the groups there may be a different amount of light bulbs - it can be like alone, so ten and more lamps. But the two-lying switch can only control only two groups of lamps.

It is clear that if you plan to perform an open installation of the wiring, then each cable that needs to be connected to a two-lying switch and the lamp is locked in separate cable channels or corrugations.

If the wiring in the house is used for many years, and the existing electric pipes are not suitable, they will need to be replaced. In the event that they were mounted in an open way, there will be no problems. If they were hidden under the plaster, you will have to make new shoes and lay new cables. After placing cables in our places, they start connecting them.

Before starting work on replacing wiring in an apartment or private house and install a two-block switch for safety, it is necessary to completely disable the power supply.

To do this, it will be enough to turn off the automatic switch that stands at the beginning of the circuit designed to supply current to lighting devices.

And so, when all preparatory work is made and wires are placed according to the scheme, you can start connecting a two-block switch.

How to choose a circuit on two light bulbs

Before mounting, you should carefully read the location of the switch of the switch. Sometimes on the back of the switches, you can find a circuit of the switch of the switch, where the normally open contacts are depicted in the off position and the general output.

In a double switch there are three contacts - a common input and two separate outputs. The input is connected by the phase from the junction box, and the two outputs are controlled by the inclusion of chandelier lamp groups or other light sources. As a rule, the switch must be fixed so that the overall contact is located at thenime.

If there is no diagram on the reverse side of the switch, the contacts are defined as follows: the introductory contact is located on one side of the switch, and the two outputs to which the lighting devices are connected - on the other side.

Accordingly, there is three clamps on the two-block switch to attach the wires - one on the input contact, and one on two outputs.

So, we figured out the work of the switch. Now you need to prepare a workplace, tools and materials. We must not forget that the most important thing when performing any work related to electricity is safety.

Each of the two-layer switch keys can be installed in one of two positions, including or turning off the electrical appliance. In each of the groups there may be a different amount of light bulbs - it can be like alone, so ten and more lamps. But the two-lying switch can only control only two groups of lamps.

First you need to check the wires, that is, tested which one is phase. Using an indicator screwdriver, it is not difficult to do this: when contacting the phase in the screwdriver, the signal LED will light up.

Mark the wire so that when performing further operations do not confuse it with zero. Before starting the installation of the switch, you need to secure your work area.

If we are talking about chandelier - you should de-energize the wires coming from the ceiling. When the type of wires is defined and labeling is applied, you can turn off the power (for this you should use the appropriate automaton in the shield) and proceed with the installation of a double switch.

Decide in advance and ensure the presence of connecting material for wires.

self-consuming terminals;
screw clamps;
caps or tape for manually twisted wires.

The most convenient and reliable way is the fixation of self-activated terminals. Screw clamps can weaken over time, and the healent has the property of lose elasticity, to develop. Because of this, the reliability of the connection can significantly weaken over time.

Self-activated terminals will ensure a reliable durable connection. To properly connect the switch to the light bulb, you must carefully examine the step-by-step instructions how to do it. After that, you can not only make installation according to the scheme, but also to identify possible malfunctions. When providing electrical installation indoors, the question often arises how to pave the cable using a corrugated pipe.

2 screwdrivers - flat and crusades;
mounting or stationery or other device for removing isolation;
pASSATISIA Either SOFT;
construction level.

In the distribution The box started the power phase-zero, the trigger wire was lowered onto the switch. The phase vein connects to the general output of the switch, the other two veins will be, is a phase interrupted contacts that are returned to the distribution box and each wire goes to its lamp. Zero is general and leaves immediately with the distribution boxes on the lamp cartridge.

Why zero on the lamp, and the phase on the break on the switch, it is associated with safety. If the phase switch position does not remain on the lamp chipboard.

Imagine the fictional situation, the lamp burned out, you are trying to replace it, turned off the switch, took the aluminum stepladder, installed on the raw concrete floor and climbed to it, took the lamp cartridge, and on it the phase, through your body, through a conductive stepladder, the current will pass, consequences can Being from falling from a height to death leaving.

Hence the conclusion before doing something, it is necessary to clearly represent the expected result. It is not necessary to make a scientific tick and hope to happen.

If you correctly connect the connection, then you can enable electricity or stop it.

the ability to disconnect and include whole groups of lamps;
savings on the cable, since it does not need to pull two wires, as for single devices;
allows you to adjust lighting with a large number of lamps in the chandelier;
it is used for premises with high levels of humidity;
it does not require special care;
easy installation.

Experienced electrician Any project to improve the lighting system begins with optimizing the use of all electrical devices combined into one chain.

An example of an optimized circuit is the traditional organization of illumination of the "Toilet bathroom" block. From the side of the corridor, one switch is usually installed, but with two keys.

Thus, the lamp in the bathroom is controlled by one key, and the bulb in the toilet is the second. One movement of the hand can be made at once two actions, extinguishing the light in one room and turning on the lighting in the neighboring, which is very convenient.

If the switch is installed in the simpleness between the two parts of the bathroom, then choose the key will not be difficult - it will be from the side of the desired room

Installing the common switch into two rooms is suitable in the event that they are nearby. For the premises remote from each other, it is reasonable to use individual electrical installations.

Double switch may be required when mounting chandelier or sconium with two light bulbs. Separate control expands the functionality of the lighting device and allows you to increase or decrease the intensity of burning.

If you use one key, the lighting will be defective, when you press both keys, it becomes twice as brighter.

In order to save electricity, it is not necessary to operate both light bulbs at the same time. To create a rest atmosphere, it is enough to include only one of them

As you can see, the ability to connect a double switch into two separate light bulbs facilitates control of lighting devices or adjusting the intensity of light. When installing a single device, not only electricity is saved into two rooms, but the number of mounting materials and devices is reduced.

In order to find the cause, you need to return to the top of the installation and scrupulously perform all the steps. Armed with an indicator, you will certainly ring all the wires and march them. In case of detection of suspicion of a wire malfunction, refer to the masters. If it is not observed with wiring problems, reopened the marked wires reopened according to the scheme and be extremely attentive.

Conclusion.

Thus, a two-block electrical switch allows you to adjust the lighting intensity in one room or can be used to turn on the lamps located in different rooms. Installation work, in the presence of the necessary tool and certain knowledge, can be performed on its own.

When connecting electrical appliances, it is necessary to comply with the safety regulations. It is necessary not only to turn off the power, but also prevent a random supply of voltage. The above operating operations will be easier to be easier if you use high-quality components, tools. You should check the wiring if the installation of equipment consumes more electricity is supposed.

Having an idea of \u200b\u200bthe features of the switches design and what is a diagram of connecting a two-block switch, it is much easier to choose the right elements of the system.

With these basic knowledge, it is quite realistic to connect the switch with your own hands without referring to the help of specialists.

All connection options we have considered are the most common, you must remember the following:

first define the phase "L";
the device is placed only on the phase wire;
consider the manufacturer's recommendations;
be sure to check the strength of the deduction of the ends of the wire with screws on the terminals;
if you work, follow safety.

As you can see, there are no special difficulties in this electrical work, you only need to pay attention to the working unit and set the switch to the desired wire.

I also want to draw attention to that if you are not sure about your abilities, then better contact an experienced specialist who will fulfill such work quickly and efficiently. We hope that the recommendations from the electromanual.ru will help to fill your home with the light.

1. The junction box is the location of the wire connections and the wiring of them in different directions.

2. Twist - connecting wires to protect against excess resistance, which will lead to constant heating of contacts.

Two-block backlit switch

A backlight switch differs from the usual only in that inside it is the highlighting indicator. This indicator can be a neon lamp or a LED with a limiting resistor. The circuit of the backlit switch is pretty simple.

The indicator is connected in parallel with the switch outputs. When the lighting switch is disconnected, the backlight indicator turns out to be connected to the zero network wire through the small resistance of the lamp and lights up. When the lighting is turned on, the indicator circuit turns out to be shorted and it goes out.

Sometimes there is a need to install a two-button switch in the configuration with a socket. In this case, the additional area of \u200b\u200bthe wire is laid from the switch to the outlet. The altitude of the placement of the device is the most diverse: the main thing is to be comfortable.

How to find a phase wire? To properly connect a double switch, you should decide on the wires. Sometimes there are doubts which wire phase.

the wiring tips gently take to the sides (so as not to dock together);
turns on the voltage on the shield;
the indicator screwdriver is triggered to bare parts;
phase that wire, when touched with which light bulb will turn around.

Dimmers help control the lighting intensity. Distinguish sensory, push, swivel. Installation circuit for all species is the same.

Precautions

What measures should be taken by installing light in the house? Work with a voltage chain requires a trepidate approach, given the safety rules.

To avoid injury / accidents before connecting a two-block switch, you should properly turn off the current supply, check the availability of voltage on the introductory cable.

Work on installing sockets / switches is better to start to designer repair.
Before starting installation, check the wiring condition.
Properly organize actions in the bright time of the day (in the dark heavier to install).
Be sure to check the health of the bulbs, other details.
Using the voltage indicator, check the current failure.
Disable automatic or batch switches on home player.
In accordance with the safety standards, it is properly to use the phase red wiring.
Zero wire - blue.
All actions spend with extreme caution.
To avoid shock, special attention is paid to premises with high humidity.
Power supply of the porch, bath, basement requires the use of reinforced isolation.
The light is replaced when the electricity is turned off.
Using the stairs, the base is placed insulating rug.
After connecting the electrician in the house there should be no dangerous zones.
Contacts are joined in compliance with all technical norms.

In standard apartments, the wiring is often already carried out and the light bulbs are connected. But what if I want to build something non-standard? No need to fear pull new wires and understand the connection scheme. In fact, it is easy. Let's figure out how to connect a two-block switch to two light bulbs to enter another lamp on the wall.

Prepare a connection scheme.
Calculation of the necessary materials.
Purchase of components.
Selection of tools.

Draw a diagram of connecting a two-layer switch to two light bulbs.

If you listen to the well-known saying: "Some seven times, and one revenue", then any work begins with measurements. Therefore, it would be necessary to start our work with a campaign to the instrumental drawer for the roulette. But the trouble - we do not know what to measure. So you need to decide that we already have and what we want to get.

When entering the kitchen, we see the chandelier, switch and a small lid under the most ceiling. There is a junction box. It is called so because from there the voltage on the wires is distributed to consumers. Consumers are sockets with refrigerator, electric kettle and microwave, as well as our chandelier. Outlets do not interest us, but the chandelier is yes.

The next step will try to draw the chandelier connection scheme.

Connection diagram chandelier before replacing the switch

And now Dorisuham what we want to add is an extra light bulb on the wall.

Connection diagram of a 2-pin switch 2 light bulbs

In the previous scheme, it can be seen how to connect, and how to pull the wires between the sconce and the button is not very. Therefore, you will show another double-circuit breaker circuit on two light bulbs.

Cable laying diagram to double switch

We look again:

Now we have a one-block switch on site, and you need to put a two-block.
From the box comes out on L1 - this is our chandelier in the center of the ceiling.
From the same box you need to stretch the wire to the L2 lamp is a new lamp.

Now you need to decide on which the cable will go from the switch to the box and on to the lamp.

We make measurements and calculations

We are not trying to start a major overhaul, but try to do work with the smallest temporal and technical costs. For this there are two options:

All wiring lay in cable boxes. These are narrow hollow plastic strips with a removable top lid. They carefully look at the wall with any coating, because they have a compact form and pure white color.
Use the adjoining of the vertical plane and ceiling overlap. Even if the house is built of concrete panels, then in the corners they adjoin it loosely. And if you do not be afraid to muggy, then you can clean the joint from the shta and make a gasket on the corner. It will only be left to install the plastic channel to the switch and to the lamp.

The first option is distinguished by the speed of execution and the minimum garbage volume, but a large number of additional elements on the wall with which you need to put up. The second option makes the gasket less noticeable, but the preparation is associated with the "picking" in the wall and a large number of dust. Select the appropriate option.

Calculation of conductors

After we have decided on the route, measure the length of the wire from the switch to the intended place of installation of the lamp.

The first segment from the switch to the distribution box can be used by a multicore wire in double isolation, if it turns out to be on sale .

The cable must be purchased on the meter more to release segments to connect the score, switch and connections in the junction box. Better let it remain a little more than a little bit.

Cable and wire are different things. The wire is a single monolithic conductor or a group of twisted conductors - bare or insulated coated. The cable consists of two or more insulated conductors enclosed in a common shell.

The cable differs from the wire in the presence of several conductors enclosed in a common shell

The next step is determined by the cross section of the wires.

To calculate the section, you can use any online calculator. It can easily be found on the Internet.

We accept:

the power of the bulb is 0.1 kW (100 watts), with a margin;
10 meters long;
material - copper, because it is more reliable.

As a result, the calculated value of S \u003d 0.01554 mm 2 was obtained. Recommended cross section 0.5 mm 2.

network voltage - 220 volts;
the lamp power takes the maximum - 100 watts;
calculate the current strength i \u003d p / u \u003d 100/220 \u003d 0.4545 A.

To determine the cross-sectional area, we remember the second ratio: the conductor cross section is equal to the current divided by the current passing through it:

in order not to spend time on complex formulas, the current density for copper is taken equal to 10 A / mm 2 (with a stock);
we consider: S \u003d 0.4545 / 10 \u003d 0.04545 mm 2;
to ensure the mechanical strength of the wire, which will be laid under the plaster, take a larger cross section S \u003d 1.5 mm 2.

Online calculation showed the result three times less. For our lamp it is slightly. Even if we choose a cross section equal to 0.5 mm 2, it will still be with a ten-fold stock. But if you connect something more powerful, it is better to make a calculation on paper. Therefore, it is always worth checking the calculations on paper, and if doubts remain, it is better to be restrained and buy cable is thickening.

Calculation of cable channel

It is made as follows:

The cross-section of the box should be about 30-40% more than the thickness of the cable passing in it with isolation. On the sketch depicted two cuts of round and flat sample. With the same technical parameters, the specified dimensions are almost the same. Therefore, the calculation for the round cable is suitable for flat:

we accept: D \u003d 8 mm, it means that the area S \u003d D 2/4 * 3.14 \u003d 64/4 * 3.14 \u003d 50.24 mm 2;
the minimum possible section of the box 12 * 12 \u003d 144 mm 2;
conclusion: You can take plastic for posting minimum sections. It suits us with a reserve in almost 200%.

To properly select the size of the cable channel, calculate the cable cross section

Now, when we decided how to lay the cable and clarified it length, you can go to the store.

We purchase the necessary

The seller needs to ask about the quality of the material and about its cross section. New supplies of electrical equipment can not always be as they look like on the price tags. Sellers know about it. You can ask the following questions:

The cores are in fact copper or it is messed aluminum.
Are the transverse dimensions specified in the documentation.
Are there analogues with a complete cross section and the corresponding material as they cost.

After finding out all the details we buy:

cable;
cable channel;
lamp;
isolent;
plastic dowels and screws:
- the cable channel is attached from the calculation one point by 50 cm;
- if there are gaps, it can be fixed more often. Therefore, it would be nice to take ten more to the reserve.
switch. It is worth asking to show several species that differ in the execution of connecting contacts. Contacts may be self-armed, under the self-sufficiency and screw. Reliable taking mounting with a screw thread in a metal.

For our case, even if the cross section is different from the indicated by 30%, it is not very scary. Chinese manufacturers are sometimes instead of cross-section 1.5 and 1 mm 2 produce 1.2 and 0.75 mm 2, respectively. The power consumption is not too big, so worry about that the conductor will warm up, it is not worth it. However, it is possible to compete for your money, especially since if you lay the cable in the stroke, then it will be difficult to change it in the future and expensive.

Choose tools

We will need:

roulette;
level;
boxes;
screwdriver;
a hammer;
phase indicator;
insulating tape;
powerful plumbing or other suitable tool if you want to hide the cable under the putty;
drill or perforator for fastening the cable channel.

The channel for laying the cable can be glued to the wall with liquid nails, but if necessary, it will be impossible to carefully dismantle it.

Connecting a double switch to two light bulbs

Is it possible to prepare for connection: fix the box or remove the finishing layer on the ceiling corner with the submitted voltage?

Plastic profiles can be fixed, but not in the wiring zone. At first glance, it seems that network laying must be performed according to a certain geometric rules. If you keep in mind the ceiling angle, then it always is located. But on the walls, the wiring can be mounted in the most unpredictable way. Therefore, it is safe to fix a horizontal line by 10 cm below the ceiling, if it meets the requirements of aesthetics. In other cases, shutback to the wall and drilling is better to produce with a disabled machine to avoid short circuit.

Not always to lay the wires between points meet the geometric constructions

We pave cables from a two-block switch to the lamp

We are preparing the shorters on the selected path or install plastic box vertical and horizontal using a level.

From the double switch connections and two light bulbs, it can be seen that changing a single-block switch to two-block, we add only one wire. Just the one that we bought a single-core wire in double isolation. His pull to the box. And from there - a two-core cable to a new point of lighting. New "Tails" still remain outside the box. Old switch remove.

Now that preparatory work is completed, you can start connecting the wires.

During the repair of the power grid, never work under stress. Therefore, before starting actions with a junction box, a lighting device or something else, be sure to turn off the introductory machine on the shield.

Connect the wires in the box

The main thing is not to confuse the ends in the junction box. Before the start of work in place of the compound, we will see three twisted beams of wires: (1), (2), (3).

A visual connection diagram of a two-block switch

We remove with them isolation and wept to the sides. We are convinced that there are no tours between them.
All wires must be divorced to the sides and do not touch each other.
Remove the light bulb from the chandelier (L1) in the ceiling, remove the forks from the sockets.
We divor the ends of the removed switch (B1).
Wires that remain from the old switch, also wept to the sides
Additional ends that will be connected, remove outside the box so that they do not interfere when connected.
Turn on the machine.
We are looking for an incoming phase indicator. Since nowhere is included anything, there will be only one wire (1) - the one that we were looking for.
When the indicator is racing to the phase wire, the light bulb will start glowing
Called in a pair with it - incoming zero (2).
Checking the phase at the ends of the chandelier switch (B1). The wire that glows will be shared on a new two-block switch (5).
Disconnect the machine on the shield, connect the ends (5) and (6) found.
Connect the found wires to the switch
Turn on the machine, then the chandelier. Since light bulbs (L1) No, it will not light up, but the phase will fall onto the wire that goes to the ceiling lamp (3) and further on the wire (7). This will display the indicator.
The second wire, lying in the distribution box, together with the chandelier (8), will be connected to the input zero (2), which we previously defined in the first pair. This is the verification of the correctness of our actions.
Wires on ceiling lighting will go up, so they can be in one bundle with incoming. But the order of determining the ends does not change.
Most likely, two more wires leave from the introductory zero (1) and the phases - on the sockets (P). This is a standard wiring for the kitchen.
The simplest thing remains: turn off the machine on the panel, connect one wire of the wall lighting with the incoming zero, and the second with the end from the switch at the point (4).

It is always scary to climb electrical connections without appropriate training. But if you carefully examine the outlined order for connecting the double switch to two light bulbs, then nothing complicated will not be.
