2023-10-17

An auto power relay, also known as an automotive relay, is an electrical switch that is used to control high current loads in vehicles such as cars, trucks, and boats. It works by using a small current to activate an electromagnetic coil which then switches the larger load current on or off.

Auto power relays are used to control a variety of electrical components in vehicles, such as headlights, wipers, fans, and fuel pumps. They are also used to control the starter motor in some vehicles.

Auto power relays are designed to be durable and reliable, with the ability to handle high current loads and withstand the harsh conditions of the automotive environment. They are typically rated for 12 or 24 volts and can handle currents ranging from a few amps to several hundred amps.

Overall, auto power relays are an important component in the electrical system of vehicles, providing a safe and reliable way to control high current loads and ensure the proper operation of various vehicle systems.
