Automotive relays are essential components in modern vehicles, enabling reliable and efficient operation of various electrical systems. These small yet powerful devices act as electrical switches, allowing the control of high-current circuits through low-current control signals. While they often go unnoticed, Automotive relays play a crucial role in ensuring the smooth functioning of a car's electrical systems, from lights and airbags to climate control and engine management systems.

    A relay is essentially an electromechanical switch consisting of a coil and one or more contacts. When a current flows through the coil, it generates a magnetic field that activates the contacts, either opening or closing them depending on the relay's design. This allows the relay to control circuits that carry higher currents, without needing a large power source to do so directly.
