A relay switch is an electrically operated device that allows one circuit to control another, often using a low-power signal to manage a high-power circuit. It works like a bridge between circuits, making it essential in applications where direct control is impractical or unsafe. Relay switches are widely used in automotive systems, home appliances, and industrial machinery. For example, they enable a small dashboard switch to control large electrical loads like headlights or motors. By providing isolation between circuits and ensuring safe, efficient operation, a relay switch plays a vital role in modern electrical and electronic systems.
