The role and protection of the 5-Pin Relay
1. serve to protect the circuit from momentary overloads.
2. controlling strong currents with weak currents.
3. To improve the life of electrical appliances
Retrofitting high-power appliances, you need to buy high-current relays, otherwise it will affect the life. For example, to protect the car headlights, because the car headlights are relatively low voltage, while the power of the headlights is relatively high, if the direct control of the light bulb with the switch, will be directly through a very large current easy to burn the switch, the same reason, the horn, motor, etc.
A good Automotive Relay will be the guard in your car.
