Abstract
A keyswitch structure includes a base plate, a keycap, a lift mechanism, and a balance link. The lift mechanism connects between the keycap and the base plate such that the keycap can move up and down relative to the base plate. The balance link is formed substantially in a U-shaped profile. The middle portion thereof is rotatably disposed on the base plate; the two ends thereof are respectively formed in an L-shaped profile and rotatably inserted into two slot structures on the keycap or the lift mechanism or both. Compared with a conventional balance link formed in an n-shaped profile connecting a keycap and a base plate, the invention provides more diverse structural connections, conducive to structural miniaturization. Furthermore, a support of the lift mechanism includes a protrusion capable of being blocked by a limitation structure disposed on the base plate for controlling the rotation angle of the support.
