Touch keys, with their small travel, can be manufactured using piston-type or two-shot injection molding. However, toggle switches, with their large travel, are difficult to manufacture. Currently, very few waterproof smart products with toggle switches are available on the market. These products are not only extremely complex in structure, but also exhibit poor mass production performance. Therefore, existing technologies require further improvement and development.

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, Figures 1-3 The technical solutions of the embodiments of the present utility model are described clearly and completely.

[0024] like Figures 1-3As shown, the utility model is a waterproof sliding switch, which includes a housing 1, a toggle handle 2, a metal lever 3, a circuit board 7 and a PET film 8; a guide groove 13 is provided in the center of the top surface of the housing 1, and an open installation cavity 11 is provided on the bottom surface of the housing 1, and the circuit board 7 is correspondingly installed at the open end of the installation cavity 11; the PET film 8 is correspondingly attached to the circuit board 7, and a group of symmetrically arranged pot pieces are provided at the corresponding positions of the PET film 8, namely a first pot piece 81 and a second pot piece 82. The metal lever 3 has a shallow V-shaped structure, that is, the metal lever 3 is low in the middle and has two ends that are raised upward. A fulcrum 9 supported on the PET film 8 is formed in the center of the bottom surface of the metal lever 3. By applying pressure to the left or right end of the metal lever 3, the metal lever can be rotated to the left, back, and right along the fulcrum 9; a first lever protrusion 31 and a second lever protrusion 32 that protrude downward are respectively provided at both ends of the metal lever 3, and the first lever protrusion 31 and the second lever protrusion 32 are respectively provided corresponding to the first pot piece 81 and the second pot piece 82. The toggle handle 2 includes a toggle block 21 slidably connected to the guide groove 13 and a slide plate 22 correspondingly arranged at the bottom end of the toggle block 21. The size of the slide plate 22 is larger than the size of the guide groove 13, so that the slide plate 22 can slide along the bottom surface of the guide groove 13; a support block 24 supported on the metal lever 3 is provided at the bottom end of the toggle block 21, and a ball bearing supported on the metal lever 3 is provided at the bottom end of the support block 24. The slide plate 22 is correspondingly arranged above the metal lever 3, and a first driving protrusion 23 and a second driving protrusion 25 are respectively provided at both ends of the bottom surface of the slide plate 22. The first driving protrusion 23 and the second driving protrusion 25 are respectively arranged corresponding to the first lever protrusion 31 and the second lever protrusion 32. During operation, the toggle block 21 is moved leftward along the guide groove 13, driving the slide plate 22 to move leftward. The first driving protrusion 23 then compresses the metal lever 3 to rotate counterclockwise along the fulcrum 9. When the movement reaches the desired position, the first pot 81 is pressed downward by the first lever protrusion 31 of the metal lever, contacting the metal coating on the front of the circuit board 7, thereby achieving the conduction function on the circuit board. Conversely, when the toggle handle 2 is moved rightward along the guide groove 13, another conduction function of the circuit board can also be achieved. The waterproof sliding switch of the utility model is small in size, fast in response, can realize the functions of switching and left and right logic control, and has a wide range of applications. The use of independent modules makes it applicable to various electronic products and has a wide range of applications.

[0025] Limit blocks 10 supported at both ends of the metal lever 3 are provided on the inner side wall of the housing 1 . The limit blocks 10 can limit the left and right movement of the metal lever 3 along the PET film 8 , but do not limit the rotation of the metal lever along the fulcrum 9 .

[0026] The casing 1 is located on the side wall of the open end of the installation cavity 11 and has multiple threaded countersunk holes 12 distributed circumferentially. The circuit board 7 is fixedly connected to the threaded countersunk holes 12 by flat head screws 6. This structure can conveniently realize the disassembly, cleaning and installation of the circuit board to meet maintenance requirements.

[0027] The housing 1 has a slot located circumferentially within the guide groove 13, along with a watertight ring 4 connected therein. The watertight ring 4 is interference-supported against the top surface of the slide 22. The housing 1 also has a slot located circumferentially within the sidewall, along with an annular sealing ring 5 connected therein. This waterproof sliding switch structure meets IPX4 waterproofing requirements and provides excellent sealing performance between the switch module and the rest of the main structure.

[0028] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
