The principle of magnetic holding relay (detailed magnetic drive relay drive circuit diagram and wiring method), there are many classifications of relays, but the principle of most relays is the same. Compared with ordinary electromagnetic relays, magnetic retention relays have the advantage of low power consumption. When the coil is energized, it consumes some electric energy. After the trigger pulse disappears, the relay is kept in the original state by its internal permanent magnet. What w
