Working principle of relay module

When the relay works, the electromagnet is energized, and the keeper is drawn down to make D and E contact, and the working circuit is closed. The electromagnet loses its magnetism when it loses power, and the spring pulls the keeper up to cut off the working circuit. Therefore, a relay is a switch that uses an electromagnet to control a working circuit.
