Electronic switch
This article needs additional citations for verification. (May 2019) |
In electronics, an electronic switch or solid state switch is an electronic component or device 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 off. When an electronic switch is on, the circuit is closed and when it is off, the switch is open in the circuit.
Electronic switches have no moving parts and so are generally called solid state switches.[1] Electronic switches may use transistors, though vacuum tubes can be used as well in high voltage applications. Electronic switches also consist of complex configurations that are assisted by physical contact. Other forms of contact, such as light sensors and magnetic field sensors, are also used to operate electronic switches.
Types
The most widely used electronic switch in digital circuits is the metal–oxide–semiconductor field-effect transistor (MOSFET).[2]
Applications
Electronic switches are used in all kinds of common and industrial applications.
