    Automotive relay wiring method

    The relay has a four-leg relay and a five-leg relay. Let's talk about the four-leg relay. First find out which of the four pins of the car relay are the coils, and which two are the contacts that are connected as shown. The two pins are insulated between normally open contacts 3 and 4. The other two... read more

    The difference between relays and contactors

    The essential difference between the relay and the contactor is that the load is different. The current capacity is large for the contactor, the small is the relay, and the contactor for the main circuit and the relay for the control circuit are used. The function of the contactor is to switch on an... read more
