    The role of automotive relays

    The function of the relay is to control the relay coil with a switch, then the working contact of the relay is closed or disconnected, one end of the contact is connected with the current of the main line, and the other end is connected with the electric appliance to be controlled to realize a small... read more

    What are the production procedures for the light tact switch?

    The light touch switch mainly includes: stamping--injection--cleaning--assembly--forming--inspection and the like; and the membrane switch process is mainly: silk screen--die-cut--assembly--detection process. Both of them have high requirements on the production environment. Relatively speaking, the... read more

    What is the role of the relay coil?

    We should all know the role of the relay. As long as a certain voltage is applied across the coil, a certain current will flow in the coil, which will produce an electromagnetic effect. The armature will overcome the tension of the return spring under the action of electromagnetic attraction. To the... read more

    Why can automotive relays control large currents with small currents?

    To make it easier to understand, we divide the circuit into two parts, a low voltage (small current) circuit and a high voltage (high current) circuit. In the figure, the power supply, the switch S1, and the coil are low voltage circuit parts; the contacts, the load power supply, and the consumer ar... read more

    The role of the intermediate relay in the line

    In industrial control lines and current home appliance control lines, there are often intermediate relays. For different control lines, the role of three-phase relays is different. The functions of the intermediate relays are common in the following ways: 1. Replace the small contactor The contacts ... read more
