Abstract
A button structure has a base having a slot and a sensing element inserted into the slot. A pressure concentration element is fixedly connected by bonding to the sensing element and a key cap is mounted to the base. The key cap has a core member fixedly connected to a lower surface of a top plate of the key cap. The lower surface of the core member can be brought into contact with the pressure concentration element on application of a pressure to an upper surface of the top plate, such that the applied pressure is transmitted to the sensing element through the core member and the pressure concentration part. The sensing element is a piezoresistive film sensor.
