PROBLEM TO BE SOLVED: To provide a key switch which can be constituted thin, and can improve operation feeling by ensuring operation stroke of a key top, and to provide a keyboard device.SOLUTION: A key top 11 is supported by two link bars 21, 22. The coupling shafts 21a, 22a of the link bars 21, 22 are coupled rotatably with the lower surface of the key top 11. Two support shafts 21b, 21b of the link bar 21 and two support shafts 22b, 22b of the link bar 22 are located on the outside of a projection region on the plane of the key top 11, and supported rotatably in the bearing groove of the cover. Since the support shafts 21b, 21b are arranged on the outside of a projection region, a downward movement key top and the support shafts 21b, 21b do not interfere when the key switch is constituted thin. |
