Abstract
A keyswitch includes a board having a first magnetic portion and a pivot portion, a cap, a switch, and a support device including a first support member having first and second bodies connected to each other via an elastic connection arm. The first body has first and second end portions connected to the cap and the pivot portion respectively. The second body has a second magnetic portion and a triggering portion. A U-shaped slot is formed around the triggering portion to make the triggering portion form an elastic cantilever arm extending from the second body. When the cap is pressed to make the second magnetic portion away from the first magnetic portion at a specific distance, the triggering portion triggers the switch. When the cap is released, a magnetic force between the first and second magnetic portions drives the second magnetic portion to approach the first magnetic portion.
