A relay, also known as a relay, is an electronic control device having a control system (also known as an input loop) and a controlled system (also known as an output loop), which is commonly used in automatic control circuits, and which is actually an "automatic switch" that uses a small current to control a large current. Therefore, the circuit plays the roles of automatic regulation, safety protection, circuit conversion and the like. The relay coil is represented in the circuit by a long box symbol, and if the relay has two coils, two parallel rectangular boxes are drawn. Meanwhile, the character symbol J of the relay is marked in the long square frame or beside the long square frame. There are two ways to represent the contacts of a relay: one is to draw them directly on one side of the rectangular frame, which is more intuitive.
