The Switches are used for on/off the current in to the electronic equipments. The switches are electronic device that directs the flow of electrical signals from one side to the other. The Switches have two modes one is ON and another is OFF in the ON mode the current is flow regularly without any fluctuation but in OFF mode the flow of current is stop and the equipment is also stop that is run by the current. Switches have two pieces of metal called contacts that touch to make a circuit, and separate to break the circuit. These occupies in electronic equipment such as portable audio player, VCR, PDA, MP3 player, transmission, camera and digital audio player. In modern homes most lights are operated using switches set in walls.
The switches are device that changing the flow of current. All switches consist of an operator, contacts and a switch mechanism. These are plastic, ceramic or metal, and prevent accidental contact with live terminals of the switch. The function of the switch is designated by the terms pole, throw and break. Solid-state thyristor switches allow for control of lighting by blocking part of the alternating current for an adjustable time delay. Switches must perform the same tasks as other electrical switches though usually at lower currents. The switches are design safe, durable, and reliable. Switch therefore has a finite life, again often being rated at a given number of cycles of disconnection at a specified current.
There are mainly four type of switches used these are:
1. Push button
2. Toggle
3. Mercury switches
4. Three-way and four-way
