[0028] As Figure 1-Figure 4 As shown, the knob switch control device in this embodiment includes a switch box body and an adjustment knob 10 arranged on the switch box body. By rotating the adjustment knob 10, the functions of electrical appliances such as lighting and temperature can be adjusted. The adjustment knob 10 is a conventional accessory in the field and is not further limited here.

[0029] Specifically, the switch box body includes a front cover 20 and a rear cover 30 to which the front cover 20 is detachably connected. The adjusting knob 10 is arranged on the front cover 20, and a display screen 25 can be conventionally arranged on the front cover 20 to facilitate the display of information such as temperature. A plurality of convex teeth 21 are arranged on the inner walls on both sides of the front cover 20. The end cover 30 includes an upper body 31 and a lower body 32. The thickness of the upper body 31 is greater than that of the lower body 32. A plurality of card slots 321 are arranged on both sides of the lower body 32. The convex teeth 21 are inserted into the card slots 321. The cooperation between the convex teeth 21 and the card slots 321 can realize the rapid positioning and installation of the two. The convex teeth 21 are in a straight triangular prism structure here, which is convenient for fitting and abutting with the card slots 321.

[0030] Furthermore, a first convex plate 322 protruding outward is provided on the lower body 32, and a mounting hole 323 is provided on the first convex plate 322.
