the key cotton is arranged between the key switch and the clamping column, and one surface of the key cotton is abutted against the key switch; and

and the key penetrates through the first via hole and the second via hole, abuts against the other surface of the key cotton, and correspondingly applies pressure or removes pressure to the key switch according to stress.

Preferably, the key switch includes a bottom plate formed on the key control board, and a first protruding column protruding from the bottom plate and extending toward the key.

Preferably, the key comprises a key bottom plate and a second protruding column formed on one surface of the key bottom plate and extending towards the key switch direction.

Preferably, the first protruding column and the second protruding column are respectively abutted against the key cotton, and the first protruding column and the second protruding column are coaxial.

Preferably, the height of the second protruding pillar is greater than the sum of the heights of the first via and the engaging pillar.

Preferably, the area of the surface of the key cotton, which is abutted against the shell, is larger than the area of the surface of the shell, which is abutted against the key cotton.

Preferably, the key cotton is square or round.

The utility model has the beneficial effects that: the button switch with set up between the second block post the button is cotton, press the button compression it is right after the button is cotton the button switch exerts pressure, at this moment the button switch switches on, removes external force the cotton elastic recovery of button will the button jack-up, the switch conducting state is closed, this structural arrangement has improved the rocking phenomenon that needs the reservation clearance to lead to because of button up-and-down motion, has the characteristics that the structural arrangement is simple, manufacturing cost is lower.
