starter relay

A starter relay is an electrical component in a vehicle that acts as a switch to engage the engine's starter motor. When you turn the ignition key, the relay receives a small electrical signal and closes its internal contacts, allowing a higher current to flow from the battery to the starter motor. This process safely manages the heavy current needed to start the engine without putting excessive load on the ignition switch. Essentially, it ensures that the powerful starter motor activates promptly and reliably, enabling the engine to turn over and start running.
