Relays

Relays are electrically operated switches that use an electromagnet to mechanically operate a switch, allowing one circuit to control another. They are essential in applications where it is necessary to control a high-power circuit with a low-power signal, providing isolation between different parts of a system. Relays are commonly used in automation, control systems, and protection circuits due to their ability to manage multiple circuits and their reliability in switching operations. Their versatility makes them suitable for a wide range of applications, from simple control tasks to complex industrial processes.
