A 12V 60A relay is an electromechanical switch designed to handle high current loads (up to 60 amps) while being controlled by a much smaller voltage (12V DC). The relay operates by using an electromagnet to open or close contacts, allowing it to switch on or off a higher current circuit. The 12V refers to the voltage required to activate the relay's coil, and the 60A refers to the maximum current the relay can safely handle through its contacts.

    Relays like the 12V 60A are crucial in applications where high-current circuits need to be controlled or switched using low-power control systems, such as microcontrollers, sensors, or even manual switches. By utilizing a relay, a small current can control larger systems, providing both safety and efficiency in electrical designs.
