Abstract
A keyswitch structure includes a casing, a first support, a second support, and a pressing stem. The casing forms an accommodating space and an opening communicating with the accommodating space. The first and second supports are disposed in the accommodating space and are directly and rotatably connected with the casing; the supports are also pivotally connected with each other. The pressing stem extends into the accommodating space to be rotatably connected with the first and second supports and protrudes from the casing through the opening. The pressing stem is movable parallel to a vertical direction relative to the casing through the first and second supports. A motion of the pressing stem in the vertical direction has a top dead center and a bottom dead center. When the pressing stem is at the top dead center and the bottom dead center, it does not touch the casing in the vertical direction.
