SUMMERY OF THE UTILITY MODEL

In order to compensate the deficiency that exists among the prior art, the utility model provides a many gears key switch distinguishes each button easily audio-visually, has unsmooth sense, makes things convenient for the use of visual disorder personage.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a multi-gear key switch comprises a shell, wherein a plurality of gear keys are arranged on the shell, keycaps are sleeved outside the gear keys, and hollow marks are arranged at the top ends of the keycaps.

Furthermore, the shell is also provided with an illumination key, and the keycap is sleeved outside the illumination key.

Furthermore, a plurality of gear buttons and the lighting button are arranged in a straight line.

Furthermore, the illumination key is a press self-locking key.

Furthermore, a movable plate is connected in the shell in a sliding mode along the length direction, a trapezoidal groove corresponding to the gear key is formed in the movable plate, a movable plate return spring is arranged between one side of the movable plate and the inner wall of the shell, and except for the trapezoidal groove close to the movable plate return spring, bumps are arranged on the inner walls of the remaining trapezoidal grooves; the gear key comprises a key body, a key body reset spring and a key rod, wherein a through hole corresponding to the gear key is formed in the top of the shell, the key rod is arranged in the through hole in a sliding mode, the upper portion of the key rod extends out of the through hole and penetrates into the key body reset spring, the top end of the key rod is connected with the key body, and a self-locking groove clamped with the protruding block is formed in the lower portion of the key rod.

Furthermore, the diameter of the bottom end of the key body is larger than that of the through hole, and the keycap is sleeved outside the key body.

Compared with the prior art, the utility model discloses following beneficial technological effect has:

the utility model discloses a many gears key switch sets up the fretwork sign through the key cap top, not only can make ordinary people distinguish each button directly perceivedly, has formed the sense of concavity and convexity simultaneously, can directly distinguish the difference through feeling of touch, makes things convenient for the sight disorder personage to use.
