Definition of Relay Socket

Relay sockets accept electromechanical switches in which the variation of current in one electric circuit controls the flow of electricity in another circuit. Relay sockets are made of metal or composite materials and available in a variety of shapes, sizes, and colors. Relay sockets differ in terms of terminal type, the number of pins per blade, and socket receptacle style. Terminals are devices that terminate a conductor. They attach to posts, studs or other conductors in order to establish an electrical connection. Typically, these connections are made using screws or by soldering wires or pins. Crimp terminals use the physical compression (deformation) of a contact wire barrel around a conductor to make an electrical and mechanical connection to the conductor. Quick connect / disconnect terminals do not require the use of tools. Most relay sockets use 5, 7, 8, 10, 11, 14, or 16 pins per blade.
