Keyswitch having a slidable translation mechanism

Abstract

A keyswitch structure includes a keycap having a vertical connection member and a vertical-horizontal-translation mechanism, a baseplate having a vertical connection member, a slidable part having a vertical-horizontal-translation mechanism, and a restoring member. The vertical connection members are engaged for constraining the keycap to move relative to the baseplate substantially along a Z axis. The vertical-horizontal-translation mechanisms are engaged, so that the slidable part can perform a motion in response to a movement of the keycap toward the baseplate along the Z axis upon a pressing operation. The motion includes a displacement in a first direction. When the pressing operation is discontinued, a horizontal restoring force by the restoring member enables the slidable part to perform a motion that includes a displacement in a second direction to move the keycap away from the baseplate along the Z axis. The second direction is opposite to the first direction.
