The operating part 11 of the button 1 is exposed from the switch cavity 30 through the opening. The seat body 12 on the button 1 is inserted into the switch cavity 30. The switch assembly includes a dynamic power transmission component 41 arranged on the seat body 12 and a static power transmission sheet 4 corresponding to the dynamic power transmission component 4. 2. The static transmission sheet 42 is buried in the cover plate 32. The static transmission sheet 42 has an electrical contact portion 421 exposed in the switch cavity 30 and corresponding to the dynamic transmission component 41, and a pin 422 exposed outside the switch cavity 30. The cover plate 32 is L-shaped. The cover plate 32 includes a cover plate body 321 and a side plate 322. The cover plate body 321 covers the upper end of the frame 31. The side plate 322 corresponds to the side of the frame 31 opposite to the opening of the switch cavity 30. The corresponding static transmission sheet 42 is L-shaped extending along the cover plate 32. The electrical contact portion 421 of the static transmission sheet 42 is provided on the cover plate body 321. The static transmission sheet 42 is turned over to have an extension sheet buried in the side plate 322. The extension sheet extends from the lower end of the side plate 422 to form the pin 422. In this way, the pin 422 is guided to the lower side of the housing (such as Figure 1 As shown, when the push button switch is installed and used, the pin is located at the lower side of the housing), reducing the risk of water ingress and short circuit. The dynamic power transmission component 41 includes a dynamic contact piece 411 and a conductive spring 412. A conductive member positioning groove is provided on the seat body 12. The dynamic contact piece 411 is positioned and slidably installed in the conductive positioning groove. The dynamic contact piece 411 contacts and presses on the end surface of the cover body 321 through the spring 412, and cooperates with the electrical contact part 421 of the static power transmission piece 42 to switch different on and off positions of the switch.

[0017] In this specific embodiment, the frame 31 includes a "U" shaped frame body formed by its bottom plate 311 and side plates 312 oppositely arranged on both sides of the bottom plate 311. A first pivoting ear 3111 is provided on the bottom plate 311, and a resting boss 3121 and a clamping hole 3122 are provided on the side plate 312. A clamping head and a second pivoting ear 3211 corresponding to and cooperating with the first pivoting ear 3111 are provided on the cover plate body 321. The button 1 is installed on the housing 1 via the first pivoting ear 3111 and the second pivoting ear 3211. The cover plate body 321 rests on the resting boss 3121, and the clamping head is snapped into the clamping hole 3122. The side plate 422 is inserted between the side plates 312. A gear position positioning plate 313 that cooperates with the gear position assembly on the button 1 to form a gear position cooperation of the button on the housing 1 is installed in the "U" shaped frame body. The gear position positioning plate 313 is integrally formed and connected to the two side plates 312 and is spaced from the bottom plate 311. The seat body 12 of the button 1 has a notch 120. The gear position positioning plate 313 is inserted into the notch 120, and the gear position assembly on the button 1 is arranged in the notch 120. A spring hole is provided in the notch 120. The steel ball 22 and the gear position spring 21 are both arranged in the spring hole. The steel ball 22 is pressed against the working surface of the gear position positioning plate 313 via the gear position spring 21. The first pivoting ear adopts a pivot hole design, and the second pivoting ear adopts a shaft head design. During installation, the notch of the button is inserted onto the gear position positioning plate to limit the gear position assembly on the gear position positioning plate. A pivot head of the button is inserted into the ear hole of the first pivoting ear for preliminary installation. Then, the cover plate is inserted onto the frame 31. The clamping head on the cover plate is snapped into the clamping hole, and the pivot head on the cover plate is inserted into the shaft hole of the button, which has the advantage of convenient assembly.
