Relays

Relays are electrically operated switches that use an electromagnet to control the opening and closing of contacts. They are used to control the flow of electrical power or signals in circuits. Relays offer isolation between the control circuit and the circuit being controlled, allowing for safe switching of high-power loads or signals. They find widespread use in industrial automation, automotive electronics, control systems, and power distribution.
