摘要： 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.

摘要： A key structure includes a base plate, an illumination module, a switch circuit board, a metallic elastic element, a supporting element, a metallic pressing plate and a covering member. The metallic elastic element is disposed on the switch circuit board. The supporting element is located beside the metallic elastic element. An edge of the metallic pressing plate is fixed on the supporting element. As the metallic pressing plate is swung relative to the base plate to push the metallic elastic element, the switch circuit board is triggered by the metallic elastic element. The covering member covers the base plate and the metallic pressing plate. The covering member has a light-transmissible region. A light beam from the illumination module passes through the light-transmissible region. Consequently, the key structure is illuminated.

摘要： A luminous keyboard includes a membrane wiring board, a key structure and a light-emitting element. The membrane wiring board includes a membrane switch. The membrane switch is electrically conducted through the key structure. The key structure includes a keycap, a connecting element and a soft light-shading element. The connecting element is arranged between the membrane wiring board and the keycap. The keycap is movable upwardly or downwardly relative to the membrane wiring board through the connecting element. The soft light-shading element is connected with the keycap and arranged around the connecting element. The at least one light-emitting element provides plural light beams. After first portions of the plural light beams are transmitted through the membrane wiring board, at least portions of the plural light beams are outputted from at least one light-transmissible region of the keycap. Consequently, the light utilization efficiency is enhanced.

摘要： This application relates to illuminated dome switches and a dome switch assembly having a first contact carried by a switch base and a dome shaped structure coupled to and supported by the switch base, the dome shaped structure comprising a material that is flexible and capable of internally transmitting visible light. The switch assembly can include a second contact coupled to the dome shaped structure and arranged opposite the first contact, and a light source configured to emit visible light, the light source in optical communication with the dome shaped structure such that at least some of the visible light emitted by the light source passes into the material and is subsequently emitted by the material in a generally uniform manner.

摘要： A keyboard includes a base plate, a pressure sensing layer, a first key structure and a second key structure. The pressure sensing layer includes plural pressure sensing regions. Each of the first key structure and the second key structure corresponds to a pressure sensing region. Moreover, the first key structure and the second key structure are located over the corresponding pressure sensing regions. In response to different magnitudes of the depressing force, the corresponding pressure sensing regions are pushed by the first key structure and the second key structure. Consequently, the corresponding pressure sensing regions generate different pressure sensing signals. The pressure sensing layer can replace plural pressure sensing element. Consequently, the assembling process is simplified, and the assembling cost is reduced.

摘要： The invention proposes a key module for a key of a keyboard. The key module includes a module base, a module cover that can be coupled with the module base and a key tappet for coupling a keycap that is translucent in at least one symbol section. The module base includes at least one through-hole between a bottom section of the key module and the module cover. The module cover includes a section that is translucent for the light from a light source. The light source is a color-changeable light source for backlighting the symbol section of the keycap. The translucent section of the module cover is aligned with the at least one through-hole when the module cover is coupled to the module base.

摘要： An illuminated keyboard device includes plural keys, plural light-emitting elements and a membrane switch circuit module. Each key includes a keycap and an elastic element. Each elastic element has a protrusion. The plural elastic elements are located over plural contacts of the membrane switch circuit module and connected with the plural keycaps. The plural light-emitting elements are located under the corresponding elastic elements. Moreover, the protrusions within the elastic elements and the contacts of the membrane switch circuit module are all ring-shaped structures, and each light-emitting element is aligned with the center region of the corresponding contact of the membrane switch circuit module. Consequently, while the protrusion is moved downwardly to push the corresponding contact, a corresponding key signal is generated.
