Abstract:
1. A keyswitch comprising: a casing; a key cap; and a support device disposed between the casing and the key cap and rotatably connected to the key cap and the casing respectively, the key cap moving with the support device between a non-pressed position and a pressed position; wherein one of the casing and the key cap has a first magnetic area and the support device has a second magnetic area corresponding to the first magnetic area; when the key cap is not pressed, a magnetic attraction force between the first magnetic area and the second magnetic area keeps the key cap at the non-pressed position; when the key cap is pressed by an external force such that the second magnetic area moves away from the first magnetic area, the key cap moves with the support device from the non-pressed position toward the 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; wherein the support device comprises a first support member and a second support member, the first support member has a first linking portion, the second support member has a second linking portion, the first linking portion abuts against the second support member, and the second linking portion abuts against the first support member such that the first support member and the second support member rotates simultaneously when the key cap is pressed or the external force is removed.
