Relays

Relays are electromechanical switches that control the flow of current in a circuit. In automotive applications, relays are used to turn on and off high-power electrical components, such as headlights, stereo systems, and winches. Relays offer several advantages over traditional switches, including the ability to handle higher currents, isolate control circuits from high-power circuits, and allow for remote control of electrical components. When choosing a relay for your car, consider the voltage rating, current rating, and the number of contacts (poles) needed for your application.
