Automotive RelaysAutomotive relays are electrical components used in vehicles to control circuits. They are typically used in automotive electrical systems to switch high-current circuits on and off, such as the circuit that powers the headlights or the engine starter motor. Automotive relays are designed to handle the high currents and voltages found in vehicle electrical systems, and are typically much larger and more rugged than relays used in other applications. They are commonly used in conjunction with a control circuit, which provides a low-power signal to the relay to activate it and switch the high-power circuit on or off. Automotive relays are available in a range of sizes and configurations to suit different applications, and are an essential component of any modern vehicle's electrical system.
