Socket with switch: installation, wiring diagrams

click fraud protection

In order to save wires and space on the walls, often electrical appliances are combined with each other through junction boxes or other devices. Most often, a socket with a switch is combined in one housing, due to its practicality, this particular connection scheme has become the most popular among homeowners.

Installation options

There are several types of connections that differ in their type and principle of operation. Previously, in an apartment and a private house, sockets with switches, unconnected in one building, were mainly installed. This made it possible to interconnect the wires in the junction box, but not to combine these two electrical taps together. This option is suitable if, for some reason, it is not possible to install these consumers nearby or at the same height.

Advantages of this option:

  1. Availability. You can buy the cheapest sockets and switches for fixtures and combine them into one circuit;

  3. Simple wiring diagram. If you do everything carefully, then with the installation of the junction box and the combination of wires in it with your own hands, there will be no problems;
  4. Security. If a wiring is shorted or overloaded, the wires may melt. Due to the fact that a single, double or triple switch is installed separately from the outlet, the fire safety of the apartment is increased.

Now, more and more often, masters with such goals use a special unit (for example, manufacturers Makel - Makel, ABB - ABB), which combine an electrical outlet and a switch. The main advantage of such a connection scheme is its simplicity - you do not need to separately maintain contacts and double-check the correctness of their connection. It should also be noted that there is no need to hammer a wall in two places with a puncher, just one hole suitable for the size of the block is enough.

pros:

  1. It is easy to carry out the transfer of the system, its location is simply changed by pulling the cables;
  2. The installation height of this outlet with a switch is simply done according to European standards, you do not need to separately measure the level of each outlet;
  3. Can be used for outdoor placement, indoor, etc .;
  4. Convenient to mount on any surface. Installation in plasterboard, brick, stone, foam block is possible.

Disadvantages we can attribute the fact that if replacement of any separate part of the structure is required, then, most likely, the entire block will have to be changed.

Blocks are classified by the number of outlets and the type of light bulb or chandelier switch. You can buy a one-key, two-key, three-key option.

Separate wiring diagram

The easiest option, how to connect an outlet and a 1-key switch manufactured by Anam is to connect the wires of the network and devices to each other in a certain order in the junction box. Consider how to spend installation:

  1. It is necessary to prepare a hole in the wall if the outlet is internal, or simply the installation site - if the devices are external. Overhead sockets and switches are often used in houses with open wiring, they are simpler to installation and operation, but have lower safety performance than standard with hidden installation;
  2. By default, the junction box should include 6 wires - two from the outlet, circuit breaker and mains. They are divided into phase and zero. Separately, you need to enter (if any) grounding;
  3. First you need to connect the phase of the network and the switch. They are attached to each other by twisting and fixed with electrical tape;
  4. The zero wire goes to the outlet. If so to connect the cable, it turns out that the phase is switched - it is very convenient in everyday use;
  5. The neutral wire of the wiring is connected to the neutral cable of the outlet.

Such a combined system works very simply. When the switch is turned on, the phase of the outlet closes and an electric current begins to flow through it. You can connect an extension cord to it, any household appliance, etc. If you turn off the switch, the circuit will open. Of course, if necessary, you can connect the circuit so that each consumer operates independently of each other.

Please note that if you set the gap not to the phase wire, but to zero, then even with the switch off, the socket will be live. Therefore, electricians do not recommend using such a circuit. This option is also suitable for connecting the plug, lamp and switch, but then only one device will control the switch.

Increasingly, craftsmen are using a more modern version - this is a network system with a switch in one case. The system is very convenient and easy to use. How to install the unit with a socket and a light switch:

  1. A phase wire is removed from the shield. It must be attached to the corresponding conclusion;
  2. Switches are available with or without interlock (with protection they are often used for a bathroom or a street). Depending on this, the next step may vary. A jumper goes from the phase output of the outlet, which is combined with the switch terminal. It can be made of various materials and vary in design;
  3. Zero wires are interconnected;
  4. By default, such consumers are manufactured immediately with grounding. A grounding bus must be connected to the PE screw. They tighten it tightly or simply wrap the ground cable around the head with a loop.

Depending on the design, the connection diagram may differ from the one described, so carefully read the installation instructions for the unit.
