Normally open contact pin 4 and normally closed contact pin 5 are provided with from top to bottom on the right side wall of casing 6, still are equipped with a vertical bracing piece 7 on the bottom surface of casing 6, and the bracing piece 7 is located 2 right sides of electromagnetic component and the height of bracing piece 7 is greater than 2 heights of electromagnetic component. Be connected with a straight rod-like rotation piece 1 on the top of bracing piece 7, the central point that rotates piece 1 is articulated with bracing piece 7, so the central point that rotates piece 1 is the turning point, use this turning point to rotate as fulcrum 11, the one end that rotates piece 1 is in the top of electromagnetic component 2, the other end that rotates piece 1 is between normally open contact pin 4 and normally closed contact pin 5, the one end that rotates piece 1 and be located electromagnetic component 2 top is fixed with an armature 8, rotate piece 1, normally open contact pin 4 and normally closed contact pin 5 are the conductor, bracing piece 7 is the insulating part. When the electromagnetic component 2 is electrified in the positive direction to generate a positive magnetic field, the rotating component 1 rotates anticlockwise, the armature 8 is attracted by the electromagnetic component 2, the right end of the rotating component 1 upwarps and the left end of the rotating component 1 sinks, and the rotating component 1 is in contact with the normally closed contact pin 5; when the reverse circular telegram of electromagnetism subassembly 2 produced reverse magnetic field, rotated 1 clockwise rotation, electromagnetism subassembly 2 repels armature 8, and the left end upwarping of rotating 1 this moment, the right-hand member sinks, rotates 1 and normally open contact pin contact 4.
Furthermore, a retention component is arranged at the top of the shell and comprises a sliding sheet 3 made of an insulating material, a vertical mounting seat 9 is fixed on the top surface of the shell 6, one end of the sliding sheet 3 is fixed with the mounting seat 9, the other end of the sliding sheet 3 is pressed against the rotating piece 1, in order to enable the sliding sheet to apply pressure to the sunk end of the rotating piece, the distance between the two ends of the sliding sheet 3 is greater than the distance between the fixed end of the sliding sheet 3 and the mounting seat 9 and the fulcrum 11, and the sliding sheet 3 is deformable. Therefore, when the rotating member 1 rotates to the left/right end sinking process under the action of the magnetic field generated by the electromagnetic assembly 2, the sliding piece 3 moves along the surface of the rotating member 1 to the left/right end sinking along with the rotation of the rotating member 1, so that when the left/right end of the rotating member 1 sinks, the sliding piece 3 correspondingly moves to the left/right side of the fulcrum 11 and generates a downward pressure on the left/right end sinking of the rotating member 1.
