The electromagnetic system 3 includes a frame 4, an iron core 5 disposed within the frame 4, an upper armature 6 and a lower armature 7 disposed at both ends of the iron core 5, a magnetic steel component 8 cooperating with the upper armature 6 and the lower armature 7, and a push plate 9 connected to the magnetic steel component 8. The frame 4 is also wound with enameled wire. The contact system 2 includes a stationary contact support 10 and a moving spring 11 disposed opposite to each other, a stationary contact 12 disposed on the stationary contact support 10, and a moving contact 13 disposed on the moving spring 11. The iron core 5 and the lower armature 7 are both sheet-shaped and integrally formed. The upper armature 6 is also sheet-shaped and riveted to the upper end of the iron core 5. The lower end of the upper armature 6 is provided with a U-shaped opening 14, and the front end of the lower armature 7 is provided with a vertical part 15 placed in the middle of the U-shaped opening 14. The magnet component 8 includes an iron plate support 16 and two iron plates 17 mounted on the iron plate support 16. The iron plates 17 are positioned between the U-shaped opening 14 and the vertical portion 15. The iron plate support 16 has integrally formed first rotating shafts 18 on both sides, rotatably connected to the base 1, and an integrally formed second rotating shaft 19 at its upper end, rotatably connected to the push plate 9. When the electromagnetic system 3 is energized, it attracts the iron plates 17 of the magnet component 8, thereby pushing the push plate 9 forward, causing the moving contact 13 and the stationary contact 12 to close, thus completing the circuit.

[0021] Preferably, the base 1 has side plates 20 on both sides, the first rotating shaft 18 is rotatably connected to the side plates 20, and the front end of the U-shaped opening 14 is placed on both sides of the side plates 20. With the above structure, the side plates 20 not only connect the iron sheet support 16, but also fix the upper armature 6, thereby improving the stability of the assembly.

[0022] Preferably, the push plate 9 has slots 21 on both sides of its front end, and the movable spring 11 has buckles 22 that engage with the slots 21. This connects the push plate 9 and the movable spring 11, thereby improving the stability of the push plate 9 when it pushes the movable spring 11.

[0023] Preferably, the front end of the push plate 9 is provided with a groove 23, and the moving contact 13 is placed in the groove 23 after it is closed with the stationary contact 12, so as to isolate the electric arc.

[0024] Preferably, the push plate 9 has a shaft hole 24 at its rear end and a flared opening 25 at its front end. During assembly, the first rotating shaft 18 can be forcibly inserted into the shaft hole 24 through the flared opening 25 to facilitate assembly.

[0025] Preferably, the movable spring 11 has an inclined section 26 in the middle, and the base 1 has a positioning post 27 that abuts against the inclined section 26 to prevent the movable spring 11 from deforming, thereby improving the fatigue resistance of the movable spring 11.
