Abstract
A keyswitch structure includes a switch and a multilayer structure above the switch. The multilayer structure includes an inner flexible layer, a rigid light-transmissive cover sheet, and a flexible light-transmissive layer. The inner flexible layer has a keycap portion and a connection portion extending outward from the keycap portion. The keycap portion is located above the switch and forms a spatial character structure. The rigid light-transmissive cover sheet is disposed on the keycap portion and covers the spatial character structure. The flexible light-transmissive layer covers the inner flexible layer and the rigid light-transmissive cover sheet. A keyboard includes the keyswitch structure and a device casing carrying the keyswitch structure. The multilayer structure is fixed to the device casing. The rigid light-transmissive cover sheet is harder than the flexible light-transmissive layer and structurally protects the spatial character structure from being damaged when the keyswitch structure is pressed.
