[0019] Examples, such as Figures 1 to 6 As shown, a backlight implementation structure of a glass lifting switch is used to solve the problem that the existing integrated dial button structure cannot realize backlight indication. The main innovation of the utility model is to optimize the design of the dial button and its matching structure, so as to realize the backlight indication function on a smaller dial button. The structure includes a shell 1, a base 2 matched with the shell 1, a circuit board 3 arranged in the base 2, a group of micro switches 4 are arranged on the circuit board 3, and a push rod 5 is arranged above the micro switch 4. A lever bracket 6 is rotatably installed in the shell 1, and the lever bracket 6 acts on the push rod 5. Each lever bracket 6 is correspondingly provided with two push rods 5, which are conveniently located below the left and right sides of the lever bracket 6. The lever bracket 6 rotates to press down one of the push rods 5, thereby triggering the micro switch 4 below the push rod 5 to work.

[0020] The center of the lever bracket 6 is provided with a lever mounting hole 61, in which a lever 7 is fixedly provided, and a dial button 8 is sleeved on the upper end of the lever 7, on which a translucent symbol 81 is laser engraved, and a light guide 9 is built into the lever 7, which extends all the way to the top of the circuit board 3, and a backlight source 10 is provided on the circuit board 3 just below the light guide 9, and a layer of transparent waterproof rubber 20 is also provided above the circuit board 3. The backlight source 10 shines on the translucent symbol 81 through the light guide 9 in the middle of the lever 7, so as to realize the backlight indication of the dial button.
