Abstract
A keyswitch structure includes a keycap, a base, and two supports that are pivotally connected to each other and connected to and between the keycap and the base. The keycap can move up and down relative to the base through the two supports. In an embodiment, the two supports are pivotally connected through an engagement of a shaft with a C-shaped shaft hole. In another embodiment, each support is provided in a form of an n-shaped structure and includes a semi-shaft hole and a shaft portion at two ends of the n-shaped structure respectively. The two supports are pivotally connected by the shaft portions rotatably abutting the corresponding semi-shaft holes.

A keyswitch structure, comprising:
- a keycap;
- a base, disposed under the keycap;
- a first support, connected to and between the keycap and the base, the first support having a first shaft;
- and
- a second support, connected to and between the keycap and the base, the second support having a second C-shaped shaft hole, the first support and the second support being pivotally connected relative to a rotation axis by the first shaft fitting in the second C-shaped shaft hole, the second C-shaped shaft hole having a second opening, an opening direction of the second opening being perpendicular to the rotation axis, the keycap being up and down movable relative to the base through the first support and the second support, wherein the second C-shaped shaft hole extends along the rotation axis and has a bottom in the rotation axis, an indentation is formed on the bottom and passes through the bottom in the rotation axis, and the second opening extends parallel to the rotation axis and connects with the indentation.
