A relay is an electrically operated switch. It consists of a set of input terminals for a single or multiple control signals, and a set of operating contact terminals. The switch may have any number of contacts in multiple contact forms, such as making contacts, break contacts or combinations thereof.

Relays are used where it is necessary to control a circuit by an independent low-power signal, or where several circuits must be controlled by one signal. Relays were first used in long-distance telegraph circuits as signal repeaters : they refresh the signal coming in from one circuit by transmitting it on another circuit. Relays were used extensively in telephone exchanges and early computers to perform logical operations

This is the 5V 7A PCB Mount Sugar Cube Relay – SPDT most commonly used as switching device in electronic circuits. It is mainly used in Commonly switching circuits, For Home Automation projects to switch AC loads, To Control (On/Off) Heavy loads at a pre-determined time/condition, Used in safety circuits to disconnect the load from supply in event of failure, Used in Automobiles electronics for controlling indicators glass motors.
