[0018] As Figs. 1-3 shown,

[0019] Example 1

[0020] A central control switch group includes a housing 1. Inside the housing 1, several button components are provided. At the bottom of the housing 1, a circuit board 2 and a base 3 are sequentially arranged from top to bottom. The button component includes a slider 4 and a key 5. Inside the housing 1, several sliding cavities 6 are provided. The slider 4 is embedded in the inner surface of the sliding cavity 6 and moves along the "Z" axis direction inside the sliding cavity 6. The key 5 is clamped on the top of the slider 4. At the positions of the circuit board 2 corresponding to the sliding cavities 6 on the top, gold fingers are integrated. At the positions above the gold fingers on the top of the circuit board 2, conductive rubber pads 7 are also provided. At the positions of the sliding cavities 6 on the top of the conductive rubber pads 7, a raised portion 8 is fixedly connected. At the position of the raised portion 8 on the bottom of the conductive rubber pad 7, a nickel sheet is fixedly connected. By pressing the key 5, the slider 4 moves downward along the inner surface of the sliding cavity 6, squeezing the nickel sheet on the conductive rubber pad 7 to contact the gold finger for conduction, so as to achieve the effect of activating the control switch. Compared with mechanical keys, the structure is simpler and more compact, and its influence on the effect to be achieved by the switch due to movement wear is very small, which improves the stability and service life. The conductive rubber pad 7 is used to protect the circuit board 2 to prevent its gold finger from contacting water and causing a short circuit, further improving the service life. The function of the raised portion 8 is to absorb the pressing force and then release it to help the slider 4 reset. There are four sliding cavities 6, and they are distributed in a "field" shape. The button components in the same column have the same structure and are symmetrically arranged, saving the types of molds, reducing production costs, and reducing maintenance costs. At the corresponding positions near the bottom on the left and right sides of the inner surface of the sliding cavity 6, blocks 9 with a "triangle" cross-section are fixedly connected. At the positions of the blocks 9 on the outer surface of the slider 4, long waist-shaped limiting holes 10 are opened to cooperate with them. The cooperation between the block 9 and the long waist-shaped limiting hole 10 is used to limit the up and down movement range of the slider 4 in the sliding cavity 6. Moreover, the gap between the block 9 and the long waist-shaped limiting hole 10 is 0.05 mm - 0.1 mm, reducing the possibility of the slider 4 shaking in the sliding cavity 6 and ensuring that the slider 4 can slide. Inside the slider 4, embedding holes 11 are also provided. Light guide bars 12 are embedded in the embedding holes 11. The light guide bars 12 extend to the positions on the top of the conductive rubber pads 7. At the positions near the ends of the light guide bars 12 on the circuit board 2, lamp beads are integrated. After pressing the key 5 and moving downward, when the nickel sheet at the position of the raised portion 8 contacts and conducts with the gold finger, the lamp beads light up, and the light is displayed on the surface of the key 5 through the light guide column as the information feedback of the key 5, making it more intuitive.

[0021] The solution of this application can be used for the R & D requirements of the central control switch of the Hunter model. This central control switch integrates the functions of controlling the OFFROAD of the vehicle, tank turning, front axle differential lock and rear axle differential lock.
