Abstract
A keyswitch structure includes a lift mechanism and a keycap. Two supports of the lift mechanism support the keycap. There can be a spring structure connecting the two supports for driving the two supports to lift the keycap. The lift mechanism defines a central space extending through the whole lift mechanism in a vertical direction. The spring structure does not enter the central space. The two supports abut against and constrain each other through corresponding structures, to mutually rotate with respect to a rotation axis. The keyswitch structure can include a switch. The switch includes an intermediate support, detachably abutting downward against the lift mechanism or the keycap, and a resilient part, detachably abutting downward against the intermediate support. In the process of pressing the keycap, the intermediate support is separated from the lift mechanism or the keycap, so that the contact force of the switch can be maintained constant.
