Abstract
A key structure includes a supporting plate, a keycap, a scissors-type connecting element, a movable element and a coupling structure. The keycap is disposed over the supporting plate. The coupling structure is connected with the scissors-type connecting element and the movable element. For operating the key structure, the cooperation of the movable element and the coupling structure allows the keycap to be at a higher first height. Consequently, the tactile feel of depressing the key structure is enhanced. Moreover, the cooperation of the movable element and the coupling structure can lower the height of the keycap. Consequently, the key structure has a slim appearance.
