Product Advantages

Control circuit on and off:

Like an intelligent switch, it can control the connection and disconnection of the motor circuit according to the signal sent by the vehicle control system. For example, when the driver turns the key to start the vehicle, the relay receives the signal and closes the contact, allowing the current to flow from the battery to the starter motor, allowing the starter motor to start the engine; after the engine starts, the relay will disconnect the circuit according to the relevant signal to prevent the starter motor from continuing to work14.

Protect circuits and equipment:

When the circuit is abnormal, such as current overload, short circuit, etc., the protection mechanism in the relay will be triggered, and the circuit will be quickly cut off to prevent the motor, battery and other related electrical equipment from being damaged due to overcurrent and other problems, thereby extending the service life of these components and ensuring the safe and stable operation of the vehicle's electrical system.
