A common use is control of lighting, where multiple switches may be wired into one circuit to allow convenient control of light fixtures. Special types are used, for example, for control of machinery, to reverse electric motors, or to sense liquid level. Multiple forms of actuators are used for operation by hand or to sense position, level, temperature or flow. Switches in high-powered circuits must operate rapidly to prevent destructive arcing, and may include special features to assist in rapidly interrupting a heavy current. A switch will have one or more sets of contacts, which may operate simultaneously, sequentially, or alternately.

It may be operated manually, for example, a light switch or a keyboard button, may be operated by a moving object such as a door, or may be operated by some sensing element for pressure, temperature or flow. The mechanism of a switch removes or restores the conducting path in a circuit when it is operated.

Making our world good, let 's share.In electrical engineering, a switch is an electrical component that can 'make' or 'break' an electrical circuit, interrupting the current or diverting it from one conductor to another.
