Abstract
A keyswitch includes a key cap, a base, a first support member, a second support member and a link member. The base has a first restraining portion and a third restraining portion. The first support member is disposed between the key cap and the base. The first support member has a second restraining portion. The first restraining portion restrains the second restraining portion from moving in a direction perpendicular to the base. The second support member is disposed between the key cap and the base and opposite to the first support member. The second support member has a fourth restraining portion. The third restraining portion restrains the fourth restraining portion from moving in the direction perpendicular to the base. When the key cap is pressed to a bottom of the base, the second and fourth restraining portions are located under the first and third restraining portions respectively.
