[0022] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "front", "back", "inside", "outside", "vertical", "horizontal" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore are not to be construed as limiting the present invention. In addition, the terms "first", "second" and "third" are only used for descriptive purposes and are not to be construed as indicating or implying relative importance.

[0024] like Figure 1-5 It is a structural schematic diagram of a touch switch of a preferred embodiment of the utility model. In this embodiment, a touch switch includes a base 1 and a cover plate 4. An installation cavity 11 is opened in the base 1, and a contact spring 2 is installed in the installation cavity 11. A pressing block 3 is in contact with the top of the contact spring 2, a through hole 43 is opened in the middle of the cover plate 4, and the pressing block 3 moves in the through hole 43, and a limit plate 42 and an elastic buckle 41 are symmetrically fixedly connected around the cover plate 4. The limit plate 42 cooperates with the elastic buckle 41 to fix the cover plate 4 on the base 1, and a clamping position 12 is opened at the bottom of the base 1 at a position opposite to the elastic buckle 41, and the elastic buckle 41 is clamped in the clamping position 12; combined with the arrangement of the above structure, the internal structure of the touch switch is simplified, the volume of the touch switch itself is reduced, and it can be suitable for a smaller installation space.

[0025] In this embodiment, a first contact block 13 is fixedly connected in the middle of the installation cavity 11, and second contact blocks 14 are fixedly connected on both sides of the first contact block 13 in the installation cavity 11. The first contact block 13 and the second contact block 14 are in contact with the bottom surface of the contact spring 2, so that the operator presses the pressing block 3, and each time the pressing is performed, the center of the contact spring 2 is in contact with the first contact block 13; it should be noted that the second contact block 14 is in a state of constant contact with the contact spring 2.

[0026] In this embodiment, the pressing block 3 includes a convex bump 33, a connecting plate 32 and a cap 31. The cap 31 is fixedly connected to the top of the connecting plate 32, and the convex bump 33 is fixedly connected to the bottom of the connecting plate 32. The bottom surface of the convex bump 33 is in contact with the contact spring 2, so that the center point of the contact spring 2 is better in contact with the first contact block 13, reducing the position deviation of each pressing. At the same time, the cap 31 moves in the through hole 43, and the cap 31 is in contact with the operator.

[0027] In this embodiment, an avoidance position 44 is provided around the through hole at the bottom of the cover plate 4 to better facilitate the installation of the connecting plate 32 and effectively prevent the connecting plate 32 from being unable to be installed due to being too large.

[0028] In this embodiment, the bottom surface of the avoidance position 44 conflicts with the top surface of the connecting plate 32 at the same time. This design can better achieve the limiting effect and effectively prevent the pressing block 3 from popping out and falling off after each pressing.

[0029] In this embodiment, a circular hole 45 is opened on the elastic clip 41 to facilitate subsequent disassembly for maintenance and reduce production costs. The elastic clip 41 is bent inward and snapped into the snap-in position 12. The setting of this structure replaces the penetrating V-shaped snap-in design, so that the cover 4 can be better snap-fitted and fixed to the base 1, thereby increasing the connectivity between them.

[0030] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
