A relay is an electrical switch that opens and closes circuits using an electromagnet. It allows a low-power signal to control a high-power circuit. When current flows through the coil inside the relay, it creates a magnetic field that moves a switch, turning the connected device on or off. Relays are commonly used in control panels, automotive systems, and industrial machines for switching applications and safety purposes.
