Abstract

A keyswitch includes a casing having a first magnetic area, a key cap, and a support device including first and second support members rotatably connected to the key cap and the base plate. The first support member has a receiving opening and a second magnetic area disposed within the receiving opening. When the key cap is not pressed, a magnetic attraction force between the first and second magnetic areas keeps the key cap at a non-pressed position. When the key cap is pressed by an external force, the key cap moves with the support device toward a pressed position. When the external force is removed, the second magnetic area moves toward the first magnetic area due to the magnetic attraction force such that the key cap moves with the support device from the pressed position toward the non-pressed position.
