Abstract: A keyswitch structure includes a base plate, a keycap, and a support mechanism. The support mechanism supports the keycap above the base plate. An outer support of the support mechanism includes a reinforcing body and a connecting structure fixed on the reinforcing body. The outer support is connected to the base plate and the keycap through the connecting structure. In an embodiment, the reinforcing body has two openings. Two inner supports of the support mechanism are pivotally connected to the connecting structure and are located in the two openings, respectively. In another embodiment, the reinforcing body as a whole extends along a plane. The reinforcing body has a bent fringe, which is inserted into the connecting structure and is not perpendicular to the plane.

Abstract: A showing system and a showing method for product materials are provided. In this showing method, a material module database is created and stored, which includes a number of three-dimensional material modules corresponding to a number of material information and a number of module class information corresponding to the material information. A preview database is created, which includes the material information, a number of preview modules and a number of preview class information corresponding to the material information. The preview modules and preview class information in the preview database are timingly adjusted according to the three-dimensional material modules and the class information in the material module database. A user interface receives the material information to display the corresponding preview modules and the preview class.
