  • What is the function of low voltage switch

    1. Low-voltage circuit breakers are mainly used in low-voltage circuits to protect electrical equipment from short circuits, or when the voltage is abnormal or the current is too high, the circuit breaker can avoid some dangerous accidents. 2. The...

  • What is an Electromagnetic Relay?

    Electromagnetic relays refer to relays made using the principle of electromagnetic induction. When the relay is energized, the coil of the relay generates electromagnetism, which closes the normally open contacts of the relay to work. what is a...

  • Why do you need to use an interlock circuit composed of 2 PNP and 2 NpN to control the magnetic latching relay?

    1. The magnetic latching relay is only a kind of relay and has no direct relationship with the self-interlocking circuit, which can organize the self-interlocking circuit. Second, the interlocking and self-locking of the relay is the need to reali...
