How to install the switch

First of all, select the switch itself. It will be necessary to pay attention to the currentand voltage, as well as the presence of a quality standard badge, which is usually found on the inside of the device. It should be noted that the electric switches are designed for a certain operating current, and overload, in turn, can cause a fire. As a rule, on the packages of switches there are signs of state tests about their suitability for connection to the power grid.

In order to install a switch, you first need turn off the mains power completely in the part of the apartment in which you are goingto carry out installation. It should also be noted that it is best to carry out such work during the daytime in natural light, since it is quite difficult to install a switch using a flashlight.

After a power outage install a junction box, which can be made of metal orplastics. The diameter of such mounting boxes is 69 millimeters, and the height is 40 millimeters. There are different types of boxes, designed for both hollow and solid walls. The latter, as a rule, is made of concrete. In this case, an alabaster solution is used to secure the mounting box. The hollow walls are made of plasterboard, and the boxes are fastened in them using special paws.

To install a switch, it is necessary to take into account the type of so-called terminals, which are the points of connecting the wire to the device itself.

Consider the case when wire clamping takes place at the end of the screw inside the terminal itself. This method is considered to be the most dangerous, since the wire is pinched and is often interrupted before the end of the installation itself. Even if it was possible to fix the wire firmly enough, there is still a risk of weakening the contact, as a result of which the terminal will begin to bask and even spark.

The second option is wire clamp without screw. Consequently, the wire is simply inserted into a special contact hole with the key held down, when released, it is clamped. However, this method is also not considered reliable.

The most convenient and reliable way is to Fastening the wire with a clamping plate and screw. In this case, there is absolutely no risk of pinching or somehow damaging the wire.

To install the switch, to connect the wires Remove keys and top cover.. Then the wires are passed to the base andis fixed by one of the methods described above. We should not forget that the breaker should be installed in the breakage of the phase wire, which goes to the lamp holder. This is done in order to de-energize the power grid in case of a short circuit, and also to ensure safety when replacing cartridges and lamps.

Usually, For reliable fastening of the switch in the mounting box, special spacers and screws are used, which should be screwed very carefully,to avoid skewing the case. Next, the keys are set. Now you can check the switch for operation, for this we turn on the power supply and try to turn on and off the light.

Finally, it should be noted that in the event that you feel insecure about the ability to install the switch yourself, we recommend that you turn to professional electricians for help.
