Relays

Relays are electromagnetic switches that control the flow of electric current in a circuit. Comprising an electromagnet and a set of contacts, relays respond to a small input signal by magnetically closing or opening the contacts. Commonly used to amplify or isolate signals, relays ensure the safe operation of high-power devices. They facilitate automation by allowing low-power circuits to control larger loads, serving as vital components in industrial machinery, automotive systems, and electronic applications. With variations like solid-state relays offering semiconductor-based alternatives, relays play a crucial role in electrical control, protection, and signal routing in diverse technological domains.
