Socket with switches in one housing - installation, connection and cost

In modern residential design, elements of electrical fittings are often combined into one housing. In particular, this applies to sockets with switches, which can significantly reduce the amount of time for their installation and increase ease of use.

A matter of choice

In order to choose such an electrical module, you need to go to the store and inspect the case of such a device, which should be free of chips, cracks or other defects.

It is necessary to carefully examine such a unit, because the absence of even one part in such a complex device will not allow for proper installation.

The metal parts of this device that will be energized must be made of brass, if other materials are used, the device will not last a year. However, it is worth remembering that not everything is brass that has a yellowish color, so for the right choice you need to use a magnet that is not attracted to copper alloys.

The price is very often an indicator of the quality of such devices. The high cost can be due to all sorts of add-ons, for example, a lighted outlet, child protection, moisture protection, will always cost more, and such a device must be purchased if such improvements are needed.

When purchasing such combined blocks, pay attention to the mechanism for attaching wires to such a device. If threaded connections are used to fasten the wires, then the purchase should be abandoned, because it is enough to break the thread in one so that the entire device is inoperative.

Price for popular models

The price of the combined unit always depends on the configuration. An outlet with one switch is always cheaper than a model equipped with 2 or 3 of them.

Most popular models:

Viko Vera white 90681186

The horizontal module is intended for indoor installation. The device has 1 light switch and 1 socket that is not equipped with grounding, which is a big minus when organizing the power supply of modern devices.

In the event that it is not planned to turn on powerful devices, and only 1 switch is enough to organize lighting, then this model is ideal for this purpose, because the price of such a unit is only 200 rubles.

Viko Palmiye gray 90555581

This system is equipped with one switch, but often this is enough to organize a normal one. Viko Palmiye gray 90555581 has a degree of protection IP54, which allows you to install it in conditions of high humidity.

The price of the device is 300 rubles.

UNIVersal Olympus O0039

Vertical block consisting of a switch and a socket with grounding. The body of this unit is made of high quality plastic. The switch is equipped with an indicator, which makes it easy to find its location in the dark.

The block price is 225 rubles.

UNIVersal Olympus O0033

Horizontal block consisting of 1 earthed socket and 2 switches. Such a device allows you to adjust the intensity of lighting or use switches to illuminate different sectors of the same room.

The price is 230 rubles.

This electrical module combines 3 switches and 1 socket in one housing, which makes it possible to use the unit very effectively where there is a need to adjust the intensity of lighting in a room or its individual sectors. The socket is equipped with grounding and special shutters that close its contacts from "unauthorized" access to them by metal objects that may be there due to children's curiosity.

How to connect?

In order to carry out the correct installation of the electrical module, you will need the following materials and tools:

• screwdriver;
• copper three-core wire + 1.2, or 3-core, depending on the number of switches in the block;
• chisel;
• hammer;
• indicator screwdriver;
• gypsum plaster;

Before carrying out electrical work, the electrical circuit that supplies current to is necessarily de-energized. To do this, the circuit breakers are turned off in the switchboard, and the wires at the place of work must be checked with an indicator screwdriver for the absence of phase current.

If it is necessary to install an additional electrical device, then a strobe is made from the junction box to the intended installation site with a recess of about 2-3 cm

.

Before cutting a recess, markings are made directly on the wall. At the installation site of the combined block, the contour of the working part of such a block is also preliminarily outlined and a place for installation is already knocked out along it with a chisel and hammer, with a depth that will allow the working part to fit completely and not protrude beyond the wall level.

Installing a one-key block

Instruction:

1. When carrying out installation work on the installation of a single-key device, 2 socket boxes are used, which have a design that allows them to be combined into one unit. The socket boxes are installed in a recess in the wall, a 3-wire wire is inserted from the side of the socket, and a 1-wire wire from the side of the switch.
2. The socket boxes are fixed in the recess with a gypsum mortar.
3. When the solution is completely dry, a 3-wire wire is connected to the socket. In this case, you should carefully consider the phasing of this wire and connect the ground to the appropriate terminal. The phase wire must be connected to one of the socket terminals and brought to the switch input. "Earth" is connected to the third free terminal of the socket.
4. Switch output a single-core wire is connected, which will be directed to the lamp along the gate.
5. After the wires are connected, it is necessary to install the inner part in the socket boxes and securely fix it in the inside of the socket boxes with the help of a screw sliding mechanism.
6. Then the final stage of installation of such a device is carried out. A decorative plastic overlay is screwed to the inside with bolts. On the side of the switch, fastening is often carried out by means of a latch.

Installing a two-key block

When installing an electrical unit of this design, all work is carried out in the same way as the installation of a single-key device. Almost all two-key models do not require more space for installation and an additional socket.

All preparatory work described for the example of installing a single-key device applies to installing two-key modules. The phase wire is diverted from the common phase wire, and at the output of each switch one core is attached, which are then led to the lighting fixtures.

Installation of a three-key block

A three-key device is installed in a similar way, with the only difference being that the number of wires that will be directed from the switch to the lighting devices is 3.

1. If the installation is carried out in a wooden house, then the installation of the combined unit must be carried out using a metal socket.
2. By mounting such a module at the doorway, place it so that the switch is closer to the door than the socket.
3. If your electrical knowledge is insufficient to carry out this type of electrical work, you should entrust the installation of a socket with switches in one housing to professional electricians.
