How to wire the light switch and what should I pay attention to when wiring the light switch?

Lighting is very important, so when decorating, we will always face a problem, that is, how to connect the light switch? If the wire of the light switch is connected incorrectly, the light will not light up, and even lead to short circuit, which is very troublesome. Therefore, the wiring mode of the light switch will make many people find it difficult. How can a person who has never studied electrician knowledge and doesn't understand circuits and wires be possible? After all, electricity safety is very important. Now let Bian Xiao tell you in detail how to wire the light switch!

Types of light switches

Light switches are divided into single control switches, double control switches and three control switches. In the household light switch, if you do it automatically when you install it, the first thing you need to know is what type of light switch you connect.

Connection method of single control light switch:

1. Put the zero line directly through the lamp holder, and then put the line at the center point of the switch.

2. Connect both sides of the light switch with other models.

3. When coming out, one is connected to the center point of 220v, and the other is connected to the switch.

4. Finally, check whether the switch can work normally after being electrified.

Connection method of double control light switch:

Let's first determine the center point of the double-control switch, and the symmetry point is called left and right.

1. Connect the left and right switches in parallel with two wires. One switch is connected to the live wire, and the other switch is directly connected to the control wire.

2. Connect a wire directly to the center point and the other end to the electric light. Check whether the live wire and neutral wire between switches are connected correctly.

3. It is best to electrify the circuit to test whether it is correct, and then check whether the lamp can realize dual control.

4. This control method has potential safety hazards, and it is easy to trip, even a little trip will bring problems to the whole line. ?

Connection method of three-control light switch:

When installing the three-control light switch, everyone should pay attention to figuring out how it works. The three switches in the picture are all ordinary switches, but the positions are different, and the positions of live wire and zero wire are also very clear. In fact, only the switches 1 and 3 play a control role, and the intermediate switch 2 is only a midway switch, and its working mode is determined by judging the state of 1 and 3. Please refer to the following figure for specific connection methods:

Safety is very important when wiring the light switch, so it must be operated without power supply first. It should be noted that the installation of lamps and switch panels must be completed after painting or pasting wallpaper on the wall, and then the installation of lamps and switch socket panels. Tidying and cleaning are very important. We can't mess up the wires. After reading this article, I hope it will help you. If in doubt, be sure to make it clear first, and don't operate blindly. Safety is the most important thing.
