A fixing plate 14 is located at the bottom of the switch base 1. The switch 3 is housed within the switch slot 11. The protective cap 2 is a hollow cuboid shape that covers the switch 3. The protective cap 2 has a downwardly bent connecting plate 23. One short side of the switch base 1 has... The protective cap fixing groove 15 is provided, and the connecting plate 23 is set in the protective cap fixing groove 15 so that the protective cap 2 can move relative to the switch base 1. The protective cap 2 has downward bent side plates 22 on both sides. The two long sides of the switch base 1 have protective cap movable grooves 16. The side plates 22 are set in the protective cap movable grooves 16 and can move up and down along the protective cap movable grooves 16. In order to achieve the design effect, the switch 3 preferably uses the KW12-B model with a handle length of 16MM. The width of the protective cap fixing groove 15 is 0.5mm. The protective cap fixing groove 15 also has two protective cap fixing screw holes on the side to connect the protective cap 2 through nuts. The width of the movable groove of the protective cap 2 is 1mm.

[0028] Furthermore, the protective cap 2 is made of a machined film of standard virgin PEFT material with a film thickness of 0.3mm. The PTFE film is formed by stamping, cutting, and folding, with the folding along the dotted line. The protective cap 2 includes a top plate 21, and side plates 22 that are bent downwards on both sides of the top plate 21. A connecting plate 23 and a fixing limiting plate 24 are respectively provided at both ends of the top plate 21. A clamping plate is provided at one end of the side plate 22 near the fixing limiting plate 24. The clamping plate has a locking slot and can be bent inwards towards the protective cap 2. The locking slot on the clamping plate can be inserted. The fixed limiting plate 24 is inserted to fix it. The end of the side plate 22 near the connecting plate 23 is rounded. The connecting plate 23 is fixedly connected to the switch base 1. The outer side of the fixed limiting plate 24 is provided with a limiting ring 26. The switch base 1 is provided with a limiting clip 27 that cooperates with the limiting ring 26. After the protective cap 2 is assembled, two protective cap fixing screws 19 are installed in the screw holes 18 of the switch base and tightened to make the protective cap fixing groove 15 on the switch mounting base fully pressed. The protective cap fixing screws are 316 stainless steel self-tapping screws.

[0029] Furthermore, a screw fixing mounting base 4 is provided below the switch base 1. The screw fixing mounting base 4 is rectangular and larger than the switch base 1. The screw fixing mounting base 4 has slots 41 on both sides, and a fixing plate 14 is fastened in the slots 41. One end of the screw fixing mounting base 4 has a cable routing port 13. The bottom of the screw fixing mounting base 4 has a countersunk screw mounting hole 42 and an elastic locking clip 43.

[0030] Furthermore, both the limiting ring 26 and the limiting clip 27 are made of 316 stainless steel and penetrate the clip plate and the fixed limiting plate 24.

[0032] When this application needs to be fixed on a smooth mounting surface, apply the no-nail adhesive to the fixing plate 14, the switch wiring groove 12 (filling the wiring area), and the no-nail adhesive fixing groove 17. It can be directly fixed to the smooth mounting surface by relying on the no-nail adhesive. When this application needs to be fixed on a rough mounting surface, it can also be fixed to a rough surface such as concrete or wood by screw fixing the mounting base 4. During installation, after wiring the switch wiring groove 12, fill it with 708 silicone rubber, scrape it smooth and solidify it, and then put it into the screw fixing mounting base 4.

[0033] Furthermore, this application achieves the best effect when installed on a vertical surface. When fixing, the limiting ring 26 and the limiting card 27 should face downwards and the connecting plate 23 should face upwards. At this time, the waterproof effect is the best. It can also be installed horizontally, but the protective cap limiter must not be installed with the side away from the ground facing away.

[0034] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
