[0017] like Figures 1-5 As shown, a switch includes a base 1 and a handle 2. The base 1 contains a moving contact 3 and a stationary contact. A spring 4 is provided between the moving contact 3 and the base 1. The circuit is turned on or off by rotating the handle 2 to make the moving contact 3 swing. A middle cover 52 and an upper cover 51 are connected to the base 1. The middle cover 52 has a through hole 53 for the handle to pass through.

[0018] like Figures 2-3 As shown, the base 1 has symmetrical support seats 11 on both sides of the handle 2. Each support seat 11 has a shaft hole 12. The inner surfaces of the two support seats 11 facing each other have slots 13 communicating with the shaft holes 12. A first inclined surface 14 is provided within the slot 13, and the thickness of the first inclined surface 14 gradually increases from the outside to the inside. The handle 2 has a rotating shaft 21, which is rotatably connected to the shaft hole 12. When assembling the handle 2, the rotating shaft 21 is pressed down from the slot 13, and the handle 2 pushes the support seats 11 apart through the first inclined surface 14. Then, the rotating shaft 21 is inserted into the shaft hole 12, completing the assembly. The first inclined surface 14 serves as a guide and transition.

[0019] The rotating shaft 21 has symmetrical second inclined surfaces 22 at both ends. During assembly, align the shorter axial length of the rotating shaft 21 with the slot 13, and then press down the handle 2. The second inclined surfaces 22 make installation easier.

[0020] The length of the pivot 21 can be slightly less than or slightly greater than the distance between the first inclined surfaces 14 of the two support seats 11. The support seats 11 have a certain degree of elasticity, such as... Figure 6 As shown, when the length of the rotating shaft 21 is less than the distance between the upper ends of the two first inclined surfaces 14, the rotating shaft 21 and the axis of the shaft hole 12 can be placed parallel to each other. Then, the handle 2 is pressed down, and the rotating shaft pushes open the two support seats 11 simultaneously until the rotating shaft 21 is inserted into the shaft hole 12, and the support seats 11 return to their original shape. Figure 7As shown, when the length of the rotating shaft 21 is greater than the distance between the upper ends of the two first inclined surface portions 14, the rotating shaft 21 is first placed obliquely, one end of the rotating shaft 21 abuts against the support seat 11 on the same side, the handle 2 is pressed down, the rotating shaft 21 pushes away the support seat 11 on the same side through the first inclined surface portion 14, the distance between the two first inclined surface portions 14 is greater than the length of the rotating shaft 21, then the other end of the rotating shaft 21 is pressed down until the rotating shaft 21 is clamped into the shaft hole 12, and the support seat 11 returns to the original shape.

[0021] The support seat 11 is provided with a reinforcing rib 15 below the shaft hole 12.

[0022] The handle 2 is provided with a circular arc wall 23 outside the rotating shaft 21.

[0023] The support seat 11 is provided with a V-shaped groove 16 on the front side. In the open state, the V-shaped groove 16 can serve as a space for the lower end of the circular arc wall 23, and at the same time, the V-shaped groove 16 can serve as a limiting position when assembled, and as a lower limit position for the handle 2 to be turned down.

[0024] The basic principle, main features and advantages of the utility model are shown and described above. It should be understood by those skilled in the art that the utility model is not limited by the above embodiments, and the above embodiments and the description in the specification are only to illustrate the principle of the utility model, and simple changes and replacements of ordinary technical personnel in the art are within the protection scope of the utility model without departing from the spirit and scope of the utility model.
