Abstract
A keyswitch structure includes a base plate, a keycap, a lift mechanism connecting the keycap and the base plate, a movable part movably disposed relative to the base plate, a linking support, and a magnetic part on the base plate. The linking support has a pivotal connection portion, a magnetic portion, and a driving portion. The magnetic part and the magnetic portion produce a magnetic attraction force therebetween. When the movable part is located at a first position, the pivotal connection portion is rotatably disposed on a protruding portion of the movable part, and the magnetic attraction force drives the keycap through the linking support to move away relative to the keycap. When the movable part moves from the first position to a second position, the protruding portion moves away, so that the pivotal connection portion falls down and the keycap moves toward the base plate.
