When the button cover 22 and the button bracket 21 are installed, the foolproof posts 41 are inserted into the foolproof grooves 42 for positioning.

[0032] During implementation, the anti-foolproof post 41 on the surface of the button cover 22 is aligned with the anti-foolproof groove 42 on the button bracket 21 to achieve assembly positioning.

[0033] The button bracket 21 and button cover 22 of this utility model are bonded together by applying adhesive in the glue groove 211, so that the button cover 22 can be made of copper, aluminum, stainless steel and other materials. Because these materials can be fixed to the button bracket 21 by applying adhesive, the button bracket 21 and the fixing bracket 15 of this utility model are loosely matched by four buckle grooves 31 and buckles 32, and the pressing and rebound functions are realized by the rocker spring 33 and the pressing block 34.

[0034] Working principle: In use, the switch body assembly 1 and panel assembly 2 are first assembled separately. When assembling the switch body assembly 1, the high voltage group 13 is first installed inside the bottom shell 11, and then the insulating middle frame 12 is installed. After installation, four bolts are used to pass through the high voltage group 13 and thread it to the bottom shell 11. Next, the low voltage group 14 is installed on the surface of the insulating middle frame 12, and then the mounting bracket 15 is installed. After installation, four bolts are used to pass through the low voltage group 14 and thread it to the insulating middle frame 12. When assembling the panel assembly 2, the light guide 23 is installed in the four grooves on the button bracket 21. Then, glue is filled into the glue groove 211 on the edge of the button bracket 21. After filling, the anti-fooling post 41 on the surface of the button cover 22 is aligned with the anti-fooling groove 42 of the button bracket 21 to achieve assembly positioning. Finally, the glue will bond and fix the button bracket 21 and the button cover 22.

[0035] After the switch body assembly 1 and panel assembly 2 are assembled, they are installed through the snap-fit ​​assembly 3. During installation, the four snap-fits 32 are aligned with the four snap-fit ​​slots 31 and inserted to make them loosely fit together. After insertion, the spring force of the rocker spring 33 will push against the pressing block 34 upward, pressing and tightening the loose fit between the snap-fit ​​slots 31 and the rocker spring 33, thus completing the installation of the switch body assembly 1 and panel assembly 2.
