Please refer to FIGS. 1 to 7, which show a preferred embodiment of the present invention. The switch assembly with limit function of the present invention includes a body 1 and a driving structure 2.

The body 1 is provided with a rotating shaft 12 which rotates along an axis 11.

The driving structure 2 is synchronously provided on the rotating shaft 12 and includes a limiting portion 3 and a handle portion 4, one of the body 1 and the limiting portion 3 is provided with at least one clamping member 31, and the other is provided At least one missing slot 13, the at least one clamping member 31 is made of metal, the handle 4 is made of non-conductive material, the clamping member 31 is limited to the missing slot 13 to limit the rotation range of the rotating shaft 12, by pulling the handle The portion 4 drives the rotating shaft 12 to selectively open and close the body 1. In this embodiment, the handle 4 is a plastic part, the limiting part 3 and the body 1 are metal parts, thereby, since the at least one clamping member 31 is made of metal, it can have strong structural strength to avoid The at least one card The component 31 is fatigued and broken when it is stuck with the at least one missing slot 13 for a long time, so it can have strong durability, and the handle 4 is a plastic component, which can have lower manufacturing cost and improved use The comfort of the user when holding, and also avoid the risk of electric shock to the user when the body is conductive.

Specifically, in this embodiment, the at least one clamping member 31 is integrally formed on the limiting portion 3 and is bent toward the at least one notch 13 along the axial direction 11. In other embodiments, the at least one clamping member is provided It is also necessary for the body and the at least one notch to be provided in the limiting portion. In addition, in this embodiment, the body 1 is provided with two missing slots 13, and the limiting portion 3 is provided with two clamping members 31. The two missing slots 13 are respectively located on opposite sides of the rotating shaft 12, along the axial direction 11 In view of the fact that the two missing slots 13 are concave-shaped, the rotation range of the limiting portion 3 is the range in which the clamping member 31 moves on the two ends of the missing slot 13.

Preferably, the limiting portion 3 is provided with a non-circular perforation 32, the rotating shaft 12 is a non-circular cylinder, the perforating 32 of the limiting portion 3 is sleeved on the rotating shaft 12, so that the limiting portion 3 Rotate in conjunction with the rotating shaft 12. In this embodiment, the body 1 is provided with a flat surface 14, the limiting portion 3 is plate-shaped, the limiting portion 3 abuts against the flat surface 14, and the two missing grooves 13 are recessed on the flat surface 14.

Further, the handle 4 is provided with a groove 41 corresponding to the rotation shaft 12, the groove 41 is sleeved on the rotation shaft 12, so that the handle 4 and the rotation shaft 12 rotate in conjunction with each other, and the limiting portion 3 It is sandwiched between the handle 4 and the body 1 to prevent the limiting portion 3 from moving in the axial direction 11 relative to the rotating shaft 12.

Preferably, one end of the rotating shaft 12 away from the body 1 is provided with a first locking hole 121, the handle 4 is provided with a second locking hole 42 communicating with the groove 41, and a locking member 5 is formed by the handle The portion 4 penetrates through the second locking hole 42 on one side away from the body 1 and is fixed to the first locking hole 121 to fix the handle 4 to the rotating shaft 12. In this embodiment, an end of the rotating shaft 12 away from the body 1 is concavely provided with a long groove 122, and the groove bottom of the groove 41 protrudes toward the rotating shaft 12 with a convex portion 43 inserted into the long groove 122 to It further prevents the handle 4 from rotating relative to the rotating shaft 12.

In addition, the handle 4 includes an integrally formed kit 44 and a handle 45, the kit 44 is cylindrical, the groove 41 is recessed in the kit 44, and the handle 45 extends radially from the kit 44 The outer peripheral wall to increase the torque when pulling the handle 4, the handle 45 is provided with a hollow portion 451 toward one end of the body 1 to reduce the material and weight of the handle 45, the rotating shaft 12 is away from the body 1 A chamfer 123 is provided on both sides of one end along the extending direction of the long groove 122 to prevent the rotating shaft 12 and the groove 41 from wearing away. The connection between the clamping member 31 and the limiting portion 3 is radially recessed The concave arc 33 makes it easier to bend the clamping member 31, the rotating shaft 12 is rectangular columnar, and in other embodiments may be polygonal columnar with other shapes.
