Abstract:
A low travel switch assembly and systems and methods for using the same are disclosed. The low travel dome may include a domed surface having upper and lower portions, and a set of tuning members integrated within the domed surface between the upper and lower portions. The tuning members may be operative to control a force-displacement curve characteristic of the low travel dome.
Abstract:
A bonded keyboard and method for making the same are disclosed. The bonded keyboard uses adhesive as the primary agent, and in some embodiments, as the sole agent for coupling various components of the keyboard stackup together. The keyboard stackup uses a skeletal adhesive to couple a top case to a backcase assembly. In one embodiment, the skeletal adhesive is an interconnected matrix of ribs dimensioned to fit within the spacing existing between adjacent keys, which are mounted on the backcase assembly. The skeletal adhesive is fixed to the backcase assembly, occupies a portion of the spacing that exists between keys, and the top case is fixed to the top of the skeletal adhesive.
Abstract:
A key (202) and a switch housing (400) for a keyboard assembly is disclosed. A switch housing for the keyboard assembly may include a body (410) having a switch opening (402) and a light source recess (404) formed adjacent the switch opening. The switch opening may house or receive a dome switch for the keyboard assembly and the light source recess may house or receive a light source assembly (900) configured to illuminate a keycap (300) of the keyboard assembly. The switch housing also can include a top panel (412) integrally formed and molded to a portion of the body. The top panel covers the switch opening formed in the body and the top panel is a light guide.
Abstract:
An illuminated metal keycap having a legend diffuser material that may diffuse light through a legend opened in a background layer. The background layer may be opaque and the legend may be transparent. The metal 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 metal keycap, around the perimeter of the metal keycap, and/or through the background layer.
