Description Some automotive devices like wignols, starters and headlights need a lot of current to operate. If the operating voltage is very high, it is easy to cause electric shock for operators. If the operating current is large, will generate a lot of heat to burn the switch. Automobile relay is an electronic control device, usually used in an automatic control circuit. It is actually an "automatic switch" that controls a large current through a weak current. Application: Suitable for all automobiles and devices equipped with a 12 volt DC power source. Used in work lights, fog lights, starter, wipers, fans, speakers, central locking, alarm, power windows, etc. Instruction of relays and harness sockets: -85: connected to the chassis on the ground. Serves as a common ground connection to activate and magnetize the internal coil. -86: Connected to a positive input 12V DC. It is in this place that a switch connected to a DC 12V input will be connected to the relay. When the power supply is sent to the relay via the pin 86, the circuit is completed by the pin 85 connected to a common ground, which activates and magnetizes the internal coil. -87: Normally open contact, also called NO.The connection between pin 87 and pin 30 is made only when the inner coil is activated or magnetized. -30: Common contact that can be connected to a 12V DC power input or the chassis connected to the ground depending on the desired application.
