What are the switches used in electrical appliances?

According to the structure of the switch, there are micro switch, boat switch, button switch, toggle switch, key switch and so on. The main working element of the switch is the contact ( also called contact ), which is connected to and disconnected by the closure of the contact ( that is, the contact state ) and the separation. The contacts are closed by manual or mechanical action when the circuit is required to be connected; when the circuit is disconnected, the contacts are separated by manual or mechanical action. 

Contacts or reeds should have good electrical conductivity. The material of the contact is copper, copper alloy, silver alloy, silver-plated surface and silver-plated alloy on the surface. For low voltage ( such as DC 2V ) switch, and even require the contact surface of gold-plated or gold alloy. The reed requires good elasticity, and more phosphor bronze beryllium bronze with a thickness of 0.35 to 0.50 mm is used.
