[0017] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. 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.

[0018] 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.

[0019] like Figure 1-2It is a structural schematic diagram of a waterproof touch switch in a preferred embodiment of the utility model. In this embodiment, a waterproof touch switch includes a base 1, a mounting cavity 2 is provided in the base 1, a spring 4 is arranged in the mounting cavity 2, a connecting groove 3 is provided on the top surface of the base 1, a silicone button 5 is provided in the connecting groove 3, and the bottom of the silicone button 5 is in contact with the top of the spring 4, a cover plate 6 is clamped on the top of the base 1, and a through hole 61 is provided in the middle of the cover plate 6 for the silicone button 5 to pass upward. Combined with the above structural design, it simplifies the number of internal accessories of the touch switch, thereby reducing production costs and installation procedures, and improving production efficiency.

[0020] In this embodiment, fixing holes 62 are formed around the top surface of the cover plate 6, and a cylinder 11 inserted into the fixing hole 61 is fixedly installed on the top surface of the base 1. After the cover plate 6 and the base 1 are assembled, that is, after the cylinder 11 is inserted into the fixing hole 61, the cylinder 11 is riveted into a mushroom shape by a riveting machine.

[0021] In this embodiment, the inner wall surface of the mounting cavity 2 is respectively fixedly mounted with a first contact portion 21, a second contact portion 22 and a third contact portion 23, and the first contact portion 21 and the third contact portion 23 are located on both sides of the second contact portion 22. The arrangement of this structure further improves the electrical conductivity, realizes the on-off of the circuit, and achieves the function of a touch switch.

[0022] In this embodiment, the silicone button 5 includes a silicone pad 51 and a button 52. A connecting block 53 is fixedly installed on the outer wall of the silicone pad 51, and the connecting block 53 is installed in the connecting groove 3. The convex bump at the bottom of the silicone pad 51 contacts the top of the spring 4, which is convenient for pressing the spring 4 to prevent gaps between them. The button 52 is fixedly installed on the top surface of the silicone pad 51, and the button 52 moves in the through hole 61. Its structural design allows the silicone pad 51 to deform downward when the operator presses the button 52, and the convex bump at the bottom of the silicone pad 51 exerts a downward force on the spring 4, so that the bottom center of the spring 4 is in contact with the second contact portion 22, thereby realizing the on-off function of the circuit.

[0023] In this embodiment, the silicone pad 51, the button 52 and the connecting block 53 are designed with an integrated structure, so as to improve the connection strength between the silicone pad 51, the button 52 and the connecting block 53, effectively prevent cracking, and thus increase the service life of the product.
