Abstract

A key structure includes a first movable plate, a second movable plate, a keycap, a first linkage lever and a second linkage lever. The second movable plate is disposed over the first movable plate. The keycap is disposed over the second movable plate. The first linkage lever is connected with the keycap and the first movable plate. The second linkage lever is connected with the keycap and the second movable plate. While the first movable plate is moved in a first direction and the second movable plate is moved in a second direction, the first linkage lever and the second linkage lever are moved in different directions, so that a height of the keycap is reduced.
