Through the setting of the separation mechanism, under the driving action of the driving mechanism, the vibration plate is driven to reciprocate and collide with the side wall of the lower pressing frame, so that the membrane switch on the lower pressing platform is vibrated by force, and under the action of the vibration force, the edge of the membrane switch is lifted, so that the edge of the membrane switch is separated from the lower pressing platform without direct contact with the membrane switch.
