PCB Relay

PCB Relay It is a miniaturized electronic control device, in which the circuit board makes the circuit miniaturized and intuitive, which plays an important role in the mass production of fixed circuits and the optimization of electrical layout. The relay has control system (also known as input circuit) and controlled system (also known as output circuit). It is usually used in automatic control circuit. It is a kind of "automatic switch" that uses smaller current to control larger current. Therefore, it plays the role of automatic regulation, safety protection and conversion circuit in the circuit.
