Auto Relay Function Details
Dec 06, 2016

1.automotive relay switch, switch on the ignition switch, the part if under a heavy load of work overload, becomes a disconnected state, protection circuits play an important role.
2.for electricity than larger appliances (such as starter motor, electric Horn, etc), if switching control direct current switching, control switches will soon burn out. Therefore, for large current electrical equipment control, commonly used by intermediate relay way, namely through the relay contacts break and closed to control the working state of the current electrical equipment.
3.some models use a lot of small, with the internal resistance of the relay, you can save space on the Assembly, you can reduce or eliminate potential 300~500V in the circuit peak voltage in order to protect components in the electronic control system to prevent function errors.
