The invention addresses the problem of providing a pushbutton switch which can give a clear operation feeling to a person who performs a push operation, and in which the sharpness, accuracy, and brightness of an image output from a display can be increased as compared with those in the related art. A button accepts a pressing operation. Lenses focus and project an image output from a display on a diffuser plate on the top surface of the button 1. A holding member holds the lenses. Further, the holding member is configured of a combination of a spacer having a rib fitted to a rib receiver of the lens arranged on the top surface side among the lenses 15a to 15d, a spacer having a rib receiver fitted to a part of the lens arranged on the external display side, and an aperture film sandwiched between the spacer and the spacer. As a result, the above problem is resolved.

A button deck assembly includes a button deck having at least one mechanical pushbutton, the pushbutton includes a lens cap, a liquid-crystal display (LCD) panel, and an optical block configured to transmit images from the LCD panel for display through the lens cap, a bottom surface of the optical block is positioned on the LCD panel, an air gap is defined between a top surface of the optical block and the lens cap. The assembly also includes a printed circuit board (PCB) assembly defining a PCB aperture, the PCB aperture is sized to receive the optical block, and an elastomeric membrane defining a membrane aperture sized to receive the optical block, the optical block extends from the LCD panel through the PCB and membrane apertures, the membrane channels fluid flow to outer edges of the membrane and around the PCB assembly and the LCD panel.

In some examples, a computing device may include a first housing coupled to a second housing. The first housing may include a first set of components including a display device. The second housing may include a second set of components including a keyboard and a light source that emits light. An individual key of the keyboard may include one or more lenses. The one or more lenses may focus the light towards an area below an individual keycap of the individual key. For example, the one or more lenses may be integrated into a scissor mechanism of the individual key. The keycap may include an opaque material into which is embedded a character or a symbol made of a transparent or translucent material through which the light is visible.

Methods for assembling low-profile, singulated keyboards by prefabricating key assemblies onto a chassis strip that is divided into individual key assemblies only after the substrate is affixed to a feature plate of keyboard. For example, a row of key assemblies is fabricated onto a chassis strip. The row corresponds to a partial or complete row of keys of the keyboard. The chassis strip is thereafter affixed to a feature plate in a specific location, thereby aligning each prefabricated key assembly to a precise location on the feature plate. While connected, each prefabricated key assembly is independently affixed to the feature plate. Thereafter, interconnecting portions of the chassis strip between the prefabricated key assemblies are removed, thereby singulating each key assembly.

An input device includes: a printing layer on which an image of a key including a character is printed; a 3D lens that three-dimensionally floats the image of the key printed on the printing layer; and an input detector that detects an input in accordance with the depression of the image of the key floating three-dimensionally.

A control device includes at least one button, a veneer secured to an outer surface of the button, and at least one light source configured to backlight the button.
