The single-key switch today is a switching device that allows you to control the lighting in the house. It has a simple design, which is designed to perform two operations. Operations include opening and closing an electrical circuit. You can use this device if the voltage in the network does not exceed 1000 volts. The device does not have overload protection or safety shutdown.

In its design, it does not have quenching chambers and therefore is not intended for use with high current loads. The single-key light switch is by far the most common product on the domestic market. Among all the switches, this device has the simplest operation scheme. In this article, you will find information about the principle of its operation and how to disassemble a single-gang switch.

Single-key switch and its design options

Single-gang household switches can be of the following types:

• For outdoor installation.
• Internal.
• Modular.
• Waterproof.

You can only use indoor switches for flush wiring. The installation of a single-gang switch must be carried out only in the socket, which must already be installed in the wall. can also be connected using a single-gang switch.

You will need to use external switches for open wiring. They can be connected to wiring that runs through corrugated or plastic pipes. They are used in rooms where it is not possible to equip hidden wiring.

Modular light switches can be used for some types of cable channels. This variety is often used in office or industrial premises. They can only be installed in cable channels.

You will need to use moisture-proof switches in rooms that have high humidity. These rooms include a bathroom, basement or sauna. It can also be used if it can be exposed to drops of water. Manufacturers make them for indoor and outdoor installation.

The single-key switch has a fairly simple principle of operation. Now we'll talk about it. In order for you to better understand the principle of the light switch, you need to familiarize yourself with the figure that we have provided for you.

As you can see, it depicts the simplest principle of operation. Inside its mechanism is a simple moving contact, which, when pressed, will take one of two positions. In this case, the moving contact will connect or disconnect the circuit. In the picture above, your attention is given to the circuit in the off position. Now you can consider the circuit in the on position.

Here, the moving contact will complete the circuit, and current will flow through the wire to the lamp.

Why does a single-gang switch have to break the phase conductor?

When connecting a single-key switch, you definitely need to know that only a phase is connected to its contacts. Here are the basic rules for why it should be this way:

1. Current can only strike a phase.
2. In order to carry out a safe replacement of lamps, the phase must be turned off. If you have correctly connected the single-phase switch, then it is safe to change the lamp on the lamp.
3. If you make an incorrect connection, then your device may not work properly or break down. When connecting, remember that the phase must be interrupted by a switch.

These are the main reasons that will help not only extend the life of the switch, but also help protect your life. The pass switch will help turn off the light automatically.

One-button switch device

Now it's time to disassemble the light switch device. The single-key switch may consist of the following elements:

1. From plastic elements that will provide protection.
2. from the working mechanism.

The key and the frame itself can be attributed to the protective elements. The key provides translation of the on and off modes.

Under the switch button is a frame. You can attach it using two methods:

1. With plastic clips.
2. Two screws.

The switch mechanism itself will be located under the protective frame. The mechanism has a key drive.

This mechanism is mounted in the socket box in two ways:

1. With the help of spreader legs.
2. With special screws.

There will be two paws on the left and right of the device. If you start tightening the screws, then they will start to expand.

The switch device usually has two contacts to which wires must be connected. As a rule, many manufacturers pre-specify the correct fastening of the wires.

Make sure your mount is correct before running wires. If you connect the wires incorrectly, then the device will not work.

Here is a diagram of a single-gang switch.

As you can see, the single-key switch circuit is quite simple. Therefore, it will not be difficult for you to figure it out and make the correct connection of this device.
