Abstract
A keyswitch structure includes a baseplate, a keycap disposed over the baseplate and configured to be movable relative to the baseplate, a membrane switch disposed between the keycap and the baseplate and configured to have one or more buffer portions with two open edges opposite to each other, and a first linking bar connected to the keycap and disposed between the keycap and the membrane switch. The first linking bar has a first long side and a first short side connected to each other. When the keycap moves relative to the baseplate, the one or more buffer portions provide buffer to the first short side and/or an end section of the first long side.

A keyswitch structure, comprising:
- a baseplate;
- a keycap disposed over the baseplate and configured to be movable relative to the baseplate;
- a membrane switch disposed between the keycap and the baseplate and configured to have a first buffer portion with two first open edges opposite to each other;
- and
- a first linking bar only connected to the keycap and disposed between the keycap and the membrane switch, the first linking bar having a first long side and a first short side connected to each other,
- wherein when the keycap moves relative to the baseplate, the first buffer portion deforms in response to a pressing of the first short side.
