Miniaturized three-phase power magnetic latching relay

The utility model provides a miniaturized three-phase power magnetic latching relay, which comprises an upper cover, a middle shell, a bottom shell, a shielding cover, a magnetic circuit assembly, a microswitch, a magnetic steel rotating shaft combination, a pushing sheet and a pressing plate, the switch also comprises three groups of movable reed assemblies and three groups of static reed assemblies. The shielding case, the magnetic circuit assembly, the microswitch, the magnetic steel rotating shaft combination, the pushing piece and the pressing plate are all arranged in the middle shell, the upper cover covers the middle shell, and the bottom shell is supported below the middle shell; the magnetic circuit assembly provides power, the magnetic steel rotating shaft combination drives the push sheet to translate, the push sheet drives the A/B/C phase movable contact spring assemblies to move synchronously, and contact or separation of the static contact and the movable contact is achieved. The three-phase tr
