[0018] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. 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.

[0019] 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.

[0020] like Figure 1-2It is a structural schematic diagram of a composite switch of a preferred embodiment of the utility model. In this embodiment, a composite switch includes a mounting base 1, a connecting base 2 is fixedly installed on the top of the mounting base 1, and the function of connecting the composite switch to the components is realized through the connecting base 2. A mounting cavity 21 is opened in the connecting base 2, a circuit board 4 is arranged in the mounting cavity 21, and a protective cover 3 is arranged above the connecting base 2, and the two ends of the protective cover 3 are respectively connected to the surface of the connecting base 2; this structural design realizes the protection of the connecting base 2, and effectively solves the problems raised in the background technology.

A threaded hole 14 is opened on the surface of the connecting plate 12, and a slot 13 is opened on the top surface of the mounting base 1 at one side of the connecting position. A block 34 is clamped in the slot 13 to guide it and prevent the protective cover 3 from expanding outward during use, which causes the inner wall of the protective cover 3 to be unable to fit with the outer wall of the connecting plate 12.

[0022] In this embodiment, avoidance openings 35 are opened at the front and rear ends of the protective cover 3 at positions relative to the connecting seat 2, and the design avoids interference with the wiring terminals of the connecting seat 2. Connecting holes 36 are opened on the left and right sides of the protective cover 3 at positions relative to the threaded holes 14. Screws 37 are connected through the connecting holes 36 and the internal threads of the threaded holes 14 to achieve the fixing effect between the connecting plate 12 and the protective cover 3. The bottom surface of the protective cover 3 is fixedly connected with a clamping block 34 at a position relative to the clamping slot 13.

[0023] In this embodiment, the inner wall of the protective cover 3 is in contact with the outer wall of the connecting plate 12, thereby providing a better protective effect.
