Detailed Description

The following description of the preferred embodiments of the present invention will enable one skilled in the art to make and use the present invention as described below, and will more fully understand the innovative features and attendant advantages of the present invention.

As shown in fig. 1 and fig. 2, a silicone key control device includes a housing 10, and a silicone key 20 and a circuit board 30 disposed in the housing 10.

Further, referring to fig. 2, the silicone key 20 includes a silicone pad 21 and a key body 22 disposed on the silicone pad 21, the key body 22 is connected to the silicone pad 21 through a rebounding inclined wall 26, and the rebounding inclined wall 26 is disposed to facilitate the key body 22 to be pressed down and provide effective elasticity for the key body 22 to bounce.

Further, a protrusion 23 is disposed at a central position of the back surface of the key body 22, and a balance column 24 for accelerating the key body 22 to bounce is disposed around the protrusion 23.

Referring to fig. 3, under the traditional silica gel key structure, button body 22 makes button body 22 resume the normal position after pressing through bounce inclined wall 26, but button body 22 is when the position is not pressed between two parties, and carbon point 231 switches on the back with the contact of circuit board 30, and button body 22 needs the slope to bounce, and the bounce route is longer, leads to silica gel key structure bounce sensitivity poor, seriously influences work efficiency and product use experience.
