At its core, a relay is an electromechanical switch. The primary function of the 12V 60A relay is to use a small control signal to manage a larger electrical load. The relay contains an electromagnet, a set of contacts, and an armature. When a 12V signal is applied to the coil of the relay, an electromagnetic field is generated, which attracts the armature. This movement either closes or opens the contacts, consequently allowing or interrupting the flow of electricity in a separate circuit.

    The contacts can generally be classified into two types： Normally Open (NO) and Normally Closed (NC). In an NO configuration, the contacts are open when the relay is inactive, allowing no current to flow. When the relay is energized, the contacts close, completing the circuit. Conversely, in an NC configuration, the contacts are closed when the relay is inactive, allowing current to flow. Energizing the relay opens the contacts and interrupts the current flow. This functionality makes the 12V 60A relay versatile for controlling various types of devices and applications.
