100A Automotive Starter Relay, 12V/24V DC

ATO auto starter relay is an electrical component in the auto-starting system. Using a car starter relay helps protect the ignition switch from high current loads and ensures reliable engine starting. It also prevents voltage drops, making the starting process more efficient and effective. The automotive starter relay is critical to the overall performance and life of the vehicle's electrical system and starting system.

Tips: What is an automotive starter relay?

An automotive starter relay is an electromechanical switch that plays a crucial role in the vehicle's starting system. It acts as an intermediary between the battery and the starter motor. When the ignition key is turned to start the engine, a small current flows from the battery to the car starter relay. This small current activates the relay, which then closes its high-current contacts, allowing a larger current to flow from the battery to the starter motor. This large current is necessary to crank the engine and start the vehicle. The auto starter relay helps to ensure that the high current needed to start the engine does not have to pass through the ignition switch, protecting the switch from damage and ensuring reliable engine starts.
