Abstract
A keyswitch structure includes a bottom plate, a keycap, a first support, a second support, and a magnetic member. The bottom plate has a magnetic portion. The keycap is disposed above the bottom plate. The first support and the second support are disposed between the bottom plate and the keycap. The keycap is capable of moving up and down relative to the bottom plate through the first support and the second support. The magnetic member is disposed between the bottom plate and the keycap corresponding to the magnetic portion. The magnetic member and the magnetic portion induce an attractive force therebetween. The attractive force makes the magnetic member contact and apply force to the first support and the second support so that the first support and the second support tend to move the keycap away from the bottom plate.
