Electronic switch

rdf:langString Electronic switch

rdf:langString In electronics, an electronic 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. Typically, electronic switches use solid state devices such as 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. Physical contact typically comes from pressing or flipping a switch mechanically, but other forms of contact, such as light sensors and magnetic field sensors, are used to operate switches.
