[0002] A relay is an electronic control device that plays a role in automatic adjustment, safety protection, and circuit switching in circuits. It is widely used in devices for power protection, automation, motion, remote control, measurement, and communication. A magnetic latching relay typically includes a base, a magnet assembly, a moving spring assembly, and a pusher plate. The coil is wound on the frame. When the direction of the current in the coil changes, the yoke will cause the magnet assembly to rotate, thereby pushing the pusher plate, causing the moving contact to separate or close from the stationary contact.

The two movable contacts are respectively connected to the contact through holes on the first large support plate, the second large support plate, the small support plate, and the main plate.

[0008] Preferably, the large support plate one, large support plate two, and small support plate of this utility model are provided with multiple bending structures; so that there are gaps between each conductive plate, reducing the reaction force of the entire spring.
