Abstract:
A keyswitch assembly includes a movable keycap having a space provided in a bottom of the keycap; a metal support plate having an opening, the metal including a cantilever bridge; a switch located under the opening of the metal support plate; a magnet disposed within the space of the keycap; wherein as the keycap is undepressed, the keycap is in an initial state and the keyswitch assembly is OFF, and the magnet draws in the cantilever bridge, and as the keycap is depressed downward, the magnet is forced to depart from the cantilever bridge and actuates the switch making the keyswitch assembly to turn ON. As the forced is released, the magnetic force between the cantilever bridge and the magnet forces the keycap to return its initial state.
