A push-button switch and a transportation vehicle in which the disclosed push-button switch is inserted. The push-button switch has a keycap, a base plate, a switching element, a first lever and a second lever. The first lever and the second lever are each mounted for rotation on the base plate by a pivot bearing and are each movably connected to the keycap at a first lever end. The first lever and the second lever are movably connected to one another at a second lever end. The switching element is arranged on the keycap so the switching element is actuated by the second lever end of the first lever or by the second lever end of the second lever.

An illuminated glass keycap having a glyph diffuser layer that may diffuse light through a glyph window opened in a background layer. The background layer may be opaque and the glyph window may be transparent. The keycap is adhered to a scissor mechanism positioned above electrical switch circuitry. Included within, below, or adjacent to the scissor mechanism may be one or more light sources positioned to emit light through the keycap, around the perimeter of the keycap, and/or through the background layer.

An input device, such as a keyboard, includes one or more keys that each includes a keycap operable to move within an aperture of a frame to activate a switch and fabric disposed over the frame and keycap. A first region of the fabric is bonded to the keycap and a second region of the fabric is bonded to the frame. The first region may be an embossed region and the second region may be an unembossed region. The fabric may dampen sound from within the keyboard, such as noise related to movement of the keycap, activation of the switch, and so on. The fabric may also form a barrier that restricts passage of contaminants into the aperture and/or other portions of the input device.

In some embodiments, a keyboard key structure includes: a substrate; a key switch, which includes a top housing, a bottom housing. and a key stem. The top housing covers the key stem and is coupled to the bottom housing to form a cavity. The bottom housing is coupled to the substrate. The keyboard key structure further include a keycap including a light transmissive region, the keycap being configured to be coupled to the top housing of the key switch; and a light guide coupled to one side of the cavity of the key switch, the light guide comprising: a flat bottom surface; and a flat top surface wider than and parallel to the bottom surface. The top surface includes uncontinuous, trapezoidal-shaped Fresnel structures at end portions at both ends thereof. A light emitting element is coupled to the substrate and disposed under the bottom surface.

A light-emitting keyswitch includes a board, a lifting mechanism and a cap structure. The cap structure is assembled with the lifting mechanism to be movable upward and downward relative to the board and includes a cap and a light-emitting layer. The light-emitting layer includes first and second pad layers disposed on a lateral contour surface of the cap and spaced from each other, a lower electrode layer, a dielectric layer, an electroluminescent layer, an upper electrode layer and a transparent pattern layer stacked on a top surface of the cap, and an external trace structure. The lower and upper electrode layers are connected to the first and second pad layers respectively. The external trace structure is connected to the first and second pad layers for transmitting power to the upper and lower electrode layers, so as to drive the electroluminescent layer to emit light to the transparent pattern layer.

Touch sensitive mechanical keyboards and processes for detecting touch events and key depressions on the touch sensitive mechanical keyboard are provided. The touch sensitive mechanical keyboard can include a set of individually depressible mechanical keys having a touch sensitive surface. A touch sensor layer can be disposed on top of a key mechanism and flexible interconnections provided between key segments of the touch sensor layer can allow for depression of the key mechanism of individual keys. In some examples, the flexible interconnections can be formed by patterning a spring-like structure into the touch sensor layer. In some examples, the touch sensor layer can be transparent or include openings to allow a backlight to shine through. In some examples, addressable LED backlighting with buckling interconnects can also be provided to illuminate keycaps of the mechanical keyboard.

The input component includes a molding that forms an external frame, a sensor sheet formed by providing a sensor electrode on a base sheet formed of a resin film, the sensor sheet being installed inside the molding, a display element capable of being illuminated by an internal light source, a light shielding portion that shields a light from the internal light source, the display element being illuminated when the internal light source is on, a contact with the display element enabling an input operation, a colored transparent layer formed so as to have a color tone that creates a blackout in which the display element becomes integrated with the light shielding portion surrounding the display element when the internal light source is off so as to become difficult to perceive, the colored transparent layer being provided so as to be layered on the display element, and a light diffusing layer.

The mechanical keyboard includes a base plate having multiple through openings, a circuit board disposed to a side of the base plate, multiple mechanical keys disposed at the through openings and connected to the circuit board. Each mechanical key includes a keyswitch, a keycap, and at least a transparent piece. The keyswitch is connected to the circuit board. The keycap is mounted on the keyswitch, and the transparent piece is configured to a top side of the keycap. There are multiple display assemblies, each disposed inside a mechanical key between the keycap and the keyswitch. Each display assembly is data-linked to the circuit board through a signal transmission element. The display assemblies may be installed on conventional mechanical keys and may be viewed from different angles. The mechanical keyboard also has longer operation life.
