Abstract

A keyswitch structure includes a base, a keycap, a lift mechanism, and a magnetic member. The keycap is capable of moving up and down relative to the base through the lift mechanism. The lift mechanism includes a support that has a side edge portion, abutting against the base through a sharp edge, and a magnetic portion at the side edge portion. The magnetic portion extends outward from the side edge portion. The support is movably connected to the keycap through another side edge portion of the support. The magnetic member is disposed on the base corresponding to the magnetic portion. The magnetic portion and the magnetic member produce a magnetic attraction force therebetween. When an external force applied to the keycap is eliminated, the magnetic attraction force drives the support to rotate about the sharp edge relative to the base, so that the keycap moves away from the base.
