How to connect the light switch correctly? The majority of people who are used to relying solely on their own strengths for any reason do not know how to do it. Nevertheless, being guided by a clear diagram of the installation of the light switch, you can make the connection without any complications.
Taking on such a responsible event, you need to first familiarize yourself with the theory and figure out how to connect a light switch. The most successful way to compare what is in front of your eyes and what is shown in the picture will be a photo of the circuit for connecting the switch to the light bulb.
What does an external light switch look like?
The outer panel of the device has all kinds of variations:
- some modifications of the toggle switch can be keyboard or have a button that rotates (such devices contribute to less burnout of bulbs);
- there is a toggle switch equipped with an infrared sensor.
Speaking exclusively about light switches with one key, it is worth emphasizing that their fundamental function is the ability to open the circuit. During installation, a diagram of how to connect a light switch must be available.
There are other types of switches:
- two-key;
- pass-through device.
Before proceeding with the connection of the device, it is necessary to understand how the light switch with one key works.
So, the wiring diagram for a light switch with one key is the most primitive in perception and application, even for those who do not consider themselves an expert in the electrician segment.
The main nuances when connecting a one-button light switch
For the sake of safety, you must remember the precautions. Therefore, from the very beginning of the work, it is worth making sure that there is no voltage supply.
How to connect the light switch should be studied only after eliminating the potential hazard.
Connecting a one-button light switch in a junction box, we find three passing elements:
- wire for output to the lamp;
- power wire;
- two-core wire to the switch.
Then it is necessary to connect them and twist, cutting off the protective insulation.

How to conduct a light switch: assembly diagram
The figure below shows a diagram of the operation of the light switch. And in order to understand the principles of its assembly, step-by-step instructions are presented: 
- The light switch is connected directly to the break in the phase wire. The zero wire goes through the box to the lamp. The phase is necessary for us so that in the future there is no danger of electric shock.
- We connect the phase power wire to the wire that goes to the switch. The use of colored wires is suggested.
- From the switch, the phase is sent by another wire and connected to the wire going to the lamp.
- The remaining wire from the lamp is connected to the neutral power wire.
- After the work carried out, the wires are compactly placed in the box and covered with a lid.
How to connect the light through a switch should now become clear even to those who have not had the slightest experience with an electrician before. Also, all these manipulations can be viewed on the video of connecting a one-key switch, which is presented at the end of the article.
All this is serious work, as a result of which the master has:
- a neat and tidy type of switch;
- neatly folded wires, which the box for the light switch hides behind its body.
I would like to believe that after reading everyone received an exhaustive answer on how to make a light switch correctly. A video - how to connect a switch with one key - will certainly serve as a qualified guide in connecting a light switch.
