Abstract
The disclosure provides a key structure, including a first electrode, a key cap, and a restoration member. The key cap is disposed on the first electrode. The restoration member is disposed between the key cap and the first electrode. The key cap or the restoration member has a second electrode. A sensing signal is generated by the second electrode with the key cap or the restoration member moving relative to the first electrode.
Claims28
A key structure, comprising:
- a first electrode;
- a key cap, disposed on the first electrode;
- and
- a restoration member, disposed between the key cap and the first electrode, wherein the key cap or the restoration member has a second electrode, and a sensing signal is generated by the second electrode with a movement of the key cap or the restoration member relative to the first electrode.
A key structure, comprising:
- an electrode layer;
- a key cap, disposed on the electrode layer, wherein the key cap comprises a conductive material;
- an insulative base plate, disposed on the electrode layer and located between the key cap and the electrode layer;
- an elastic member, disposed between the key cap and the insulative base plate;
- and
- a connection assembly, disposed between the key cap and the electrode layer.
A key structure, comprising:
- an electrode layer;
- a key cap, disposed on the electrode layer;
