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.
Claims12
A button structure, comprising:
- a base comprising a slot;
- a sensing element inserted into said slot;
- a pressure concentration element fixedly connected by bonding to said sensing element;
- and
- a key cap mounted to said base, said key cap comprising a core member fixedly connected to a lower surface of a top plate of said key cap;
- wherein:
- said core member comprises a lower surface configured to be brought into contact with said pressure concentration element on application of a pressure to an upper surface of said top plate, such that said applied pressure is transmitted to said sensing element through said core member and said pressure concentration element;
- said sensing element comprises a piezoresistive film sensor;
- said slot comprises an opening and a groove for receiving said sensing element, and an opening direction of said opening is substantially perpendicular to said applied pressure to said key cap;
- and
- said opening direction extends in a direction extending perpendicular to a surface of said base defining said slot.
