The semi-automatic winding machine accessories - the function of the electromagnet controls the attraction or disconnection of another circuit. Inside the electromagnetic relay, key components such as coils, iron cores, springs, and contacts are required to form it. There are usually normally open contacts and normally closed contacts, both of which often have a common terminal. When the coil is not energized, the normally closed contacts and the common terminal are short circuited, thus playing a role in automatic adjustment, safety protection, and circuit conversion in the circuit.
