We connect a switch with two keys

When conducting a new wiring in the house after repair, the question often arises as to how to connect a switch with two keys in order to provide several different modes of burning light.

As is known, in order to provide artificial light in the house, it is necessary not only to hang the chandelier, but also to include a switch in the wiring diagram.

It should be noted that, regardless of what kind of lighting scheme is provided in the apartment, it will necessarily contain a switch, bulbs, and, if necessary, supplemented by an outlet.

To control the backlight in different modes, you should think about installing the switch on two separate keys, each of which will give the light bulb voltage if necessary.

Currently, the choice of switches for two separate keys is quite extensive.

You can purchase a device with a backlight, supplemented with a socket or indicator, as well as some other additional functions.

How to connect a double switch, which supplies current to the chandelier independently, is described in detail in the video below.

Design and function of the

Any switch that contains two separate switches is designed to control the operating modes of the luminaire.

With the help of it, you can apply voltage to the chandelier using a special connection scheme, in which the bulbs will light up in a certain sequence.

To understand how it works and which circuit is used to connect, you need to first disassemble its design features.

Almost all switches on two separate switches consist of a housing, terminal blocks and, accordingly, keys.

It should be noted that in some individual cases screw terminals may be provided for the terminals, however, in any case, the circuit provides for supplying one of the current clamps from the mains.

In this switch there are two parallel wires and contacts, which respectively open, and also close by the keys themselves.

Further, a through-contact is provided that allows connection to terminals or terminals, to which wires connected to a chandelier or lamp are connected.

The essence and principle of the switch on two separate keys is that it will open and, respectively, close the wires that go to the individual lamps of the lamp or the chandelier.

Very often switches that contain two separate switches are additionally equipped with a backlight and an indicator for ease of use.

Switch of this type can be seen in the photo, which is located below.

Such universal devices have certain advantages, the main one can be attributed to the ability to control the brightness of the luminaire, as well as apply voltage to the chandelier in an economical way.

The circuit for connecting the device to two separate switches has some differences from the more familiar one-button switch, but if all work is done correctly, it will be convenient to control the light.

Required materials and tool

Before you connect a two-key switch that will apply voltage to the chandelier, you must prepare the appropriate material and tools.

Also, in order to perform the job correctly, you will need a connection scheme, which, if you know the principle of its operation, you can create yourself.

If the circuit is to be made independently, then it should be taken into account that only a phase wire must pass through the switch to two keys.

Accordingly, the grounding and neutral wires must go directly to the chandelier to the contacts of the bulbs.

It should also be noted that all wiring and wiring connections should be made only in junction boxes, as shown in the photo below.

All these nuances and subtleties must necessarily contain the connection scheme, and in case it is made correctly and in accordance with generally accepted rules, there will be no problems during the work.

As an expendable material, you should have at hand a sufficient number of electric wires with a certain section, and also directly the device itself to two switches.

In addition, you will definitely need a junction box, in which the switch itself, a certain number of terminal blocks, as well as an electrical tape, will subsequently be hidden.

From the tool it is necessary to purchase a cross and flat screwdrivers, side cutters, and also a mounting knife with a sharp blade. You should also have pliers and a level.

In the event that there is a need to make a hole for podrozetnika and a groove, you will have to buy a chisel and a hammer. Care must be taken to select the switch itself.

Despite the fact that today a large selection of these devices is offered, many experts recommend paying attention to the products of the company lezard.

Switches of the brand lezard are reliable and durable, and besides, they are easy to work with.

Preparatory work for

Before you hang a chandelier and install a switch with two separate keys, you must first conduct the wiring.

If there is a concealed wiring, then they must be installed before the plaster layer is applied.

In this case, at the final stage, you only need to make the necessary connections and set the switch itself to two separate keys.

For the laying of wires, an appropriate circuit is developed, which provides for all stages of work and connection features.

After the supply wires are in place, as required by the wiring diagram, and all the necessary wiring is performed, before installing the switch on two separate keys, it is necessary to check the absence of voltage in the network.

When carrying out the wiring work independently, it is necessary first of all to install the through junction box, in which all the main connections will be made.

All cores should be connected with each other by means of a special tool, while monitoring the quality of the connection.

It is also recommended to mount a special protective device in addition to the junction box, which, if necessary, will protect the network from overloads and short circuits.

Also in the preliminary stage, the installation of the sub-socket should be done, into which the switch will be placed on two separate keys.

It is worthwhile to take care of the switch grounding device, which will only increase safety when using it.

Each stage of the work to be done should be carefully monitored and verified using a preassembled wiring diagram.

The video, which is located below, details how to independently connect the switch to two separate keys.

Performing an

connection Before you can connect the device itself, you must correctly prepare the ends of all the wires. Switches with two separate keys must be fitted with three different wires.

One of them will be input phase, and the other two output, which will supply voltage directly to the luminaire itself.

All these wires are carefully cleaned from the insulation layer, then removed to the side. Now you need to take the device itself with two keys and find the clamps on it for the wires.

It is necessary to carefully consider what kind of clamp is the input and which is the tap.

After that, the cleaned wires are inserted in them and tightly clamped.

In the event that the modular device is installed, the wiring is done a little differently.

As a rule, in such devices the terminals for phase conductors are designated by the symbol "L", in turn, the symbols for the output cables are marked with arrows.

After the device is connected and all the wires are securely fastened, it must be placed in a junction box and secured securely so as to prevent any possible reeling.

Next, it will remain on a certain scheme to connect the fixtures and you can check the device in operation.

To do this, apply voltage to the wires and alternately press each of the keys, as shown in the photo below.

Tips and tricks

Connecting devices with two separate keys allows you to adjust the amount of light in the room, if necessary.

In many ways, the working capacity of such a scheme depends on the materials and components used.

Currently in specialized stores there is a large selection of devices for two keys, but not all of them differ in quality and reliability.

Many experts recommend paying attention to the products of lezard, which offers reliable enough devices that are characterized by good durability and efficiency.

The order of performance of corresponding works plays a great role.

All necessary connections must be carried out in strict accordance with the established rules, and the work must be monitored at every stage.

Do not connect any switches or wires under voltage.
