A DC relay is an electrically operated switch designed to control high-power devices using a low-power signal. It consists of a coil and a set of contacts. When an electric current passes through the coil, it generates a magnetic field that closes or opens the contacts, allowing or interrupting the flow of direct current (DC) to the connected circuit. These relays are essential in applications where isolation between control and power circuits is needed, enhancing safety and functionality. Commonly used in automotive, industrial, and home automation systems, DC relays ensure reliable operation and protection against electrical surges, making them crucial in various electronic control systems.
