Abstract
A keyboard device includes a base plate and a plurality of keyswitches disposed on the base plate. At least one of the keyswitches includes a keycap, two linkages, and two magnetic attraction members. The linkages are connected between the base plate and the keycap and configured to guide the movements of the keycap toward and away from the base plate. The magnetic attraction members are rotatably connected to the linkages, respectively, and are configured to attract each other. When the magnetic attraction members abut against each other, the keycap is at a highest position relative to the base plate. When the keycap moves toward the base plate from the highest position, the magnetic attraction members are separated from each other.
