Relays are electrically operated switches that use an electromagnet to control one or more circuits. They allow a low-power signal to control a high-voltage or high-current circuit, making them vital in automation, control systems, and electrical protection. Commonly found in industrial machinery, home appliances, automotive systems, and power distribution panels, relays offer isolation between the control and output circuits for added safety. They are available in various types, including electromechanical, solid-state, and time-delay relays, each suited for different applications. With fast response times and reliable operation, relays enhance circuit flexibility and automation efficiency. Their compact size, affordability, and adaptability make them an essential component in both everyday electronics and complex electrical systems.
