Classification and wiring of key switches
The key switch is generally composed of a handle, a slide plate, a movable contact piece, a fixed terminal, a compression spring, a shell, etc. It is a The on and off of the movable contact and the fixed terminal contact is controlled by pressing the switch handle. There are two types of key switches: single key type and multi-key combination type. The single-button key switch is generally used as a power switch in a TV set, and it is divided into a self-locking and self-resetting type (this swi

The key switch is generally composed of a handle, a slide plate, a movable contact piece, a fixed terminal, a compression spring, a shell, etc. It is a The on and off of the movable contact and the fixed terminal contact is controlled by pressing the switch handle. There are two types of key switches: single key type and multi-key combination type. The single-button key switch is generally used as a power switch in a TV set, and it is divided into a self-locking and self-resetting type (this switch is pressed once to turn on self-locking, and then pressed again to disconnect and reset) and a non-locking type (no lock). Lock, connect when pressed, reset when released) two structures.
Key switch classification< /span>
There are two types of key switches. One is what we often say, the inside of the key switch is made of metal sheets, which is called the key switch. It is also what we can often see. However, there is also a kind of key switch, which is different from the key switch we often talk about. The internal structure of this key switch is different from the key switch we usually talk about. This kind of key switch mainly uses electric rubber as the connection circuit, and then this is also called a key switch, but there is another name, which is a conductive rubber key switch. The use of this key switch is very good, but the resistance of this key switch is relatively much larger than that of the metal sheet key switch. Generally in the 100-300n.
Key switch wiring method
Step 1 First determine the live wire and the neutral wire, both of which carry different voltages and currents.
Step 2 Connect the live wire of the power cord to the normally closed contact of the key switch, and in the same way, connect the neutral wire of the power cord to the negative pole of the switch, so that the first closure can be formed.
Step 3 Power-on test, press the button on whether it can turn on the electrical appliance, and whether pressing the off button can turn off the electrical appliance.
