Claim Text:
1. A keyswitch comprising: a base plate having a first magnetic area; a key cap; and a support device disposed between the base plate and the key cap, the support device comprising a first support member and a second support member, the first support member and the second support member being rotatably connected to the key cap and the base plate such that the key cap moves with the support device between a non-pressed position and a pressed position, the first support member having a receiving opening and a second magnetic area corresponding to the first magnetic area, the second magnetic area being disposed within the receiving opening; wherein 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 with rotation of the first support member, 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.
