Electromechanical relay

Electromechanical relays are switching devices typically used to control high power devices. In such relays the switching mechanism that is part of an operating circuit, is activated by means of a relay solenoid coil through which the switching current flows. Electromagnetic relays generally comprise two primary components including a movable conductive cantilever beam and an electromagnetic coil. Electromechanical type relays have one or more mechanical displacement electrical contacts coupled to a mobile element of the magnetic circuit of an electromagnet. The electromagnet is controlled by supplying power to its coil which drives the movement of the mobile element and the closing or opening of the electrical contacts of the relay. Over the years, electromechanical relays have found wide and varied application in the communications and electrical components. Ultraminature electromechanical relays are used in various applications, such as instrumentation, telecommunications, automatic test systems, wireless technologies, RF signal pulse generators, automotive and medical electronics, as well as commercial and general aviation and aerospace applications.
