relay An electrical control device. It has the interaction between the control system (also known as the input loop) and the controlled system (also known as the output loop). Usually used in automatic control circuit, it is a kind of "automatic switch" which uses small current to control large current operation. Therefore, it plays the role of automatic regulation, safety protection and conversion circuit in the circuit.
