Relays

Relays are electrically operated switches that use an electromagnet to mechanically open or close a circuit. They allow a low-power signal to control a high-power circuit, making them useful in applications where direct control is impractical or unsafe. Relays are used in various applications, including automotive systems, industrial controls, and home automation.

There are different types of relays, such as electromechanical relays, solid-state relays, and reed relays, each suited for specific needs. Relays provide isolation between the control circuit and the high-power load, enhancing safety and reliability. They are crucial in systems that require the remote or automated switching of electrical circuits.
