Electronic Switches

A switch is an electronic component that can switch an electrical circuit, interrupting the current or diverting it from one conductor to another. Electronic switches are considered binary devices because they can be on or completely off.

Switches contain terminals which connect to metal contacts. When the terminal and contact are touching, the switch is closed and the current can pass through. When the terminal and contact are not touching, the switch is open and the current cannot pass through the electrical circuit.
