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.
