摘要:
A silica gel key met in light guide effect and applied keypad thereof are provided. The silica gel key comprises a high transmittance silica gel body (1). Pressing projections (12) are set on the undersurface (11) of the silica gel body (1), and patterns (13) enhancing the transmittance are set on the undersurface (11) of the silica gel body (1). The keypad using the silica gel key can be applied to the electronic and communicating product such as a mobile telephone keypad and a household electric appliances keypad.

Apparatus for operating a conventional film camera (10), defining an image plane, in an electronic mode of operation including a video module (12) insertable in a camera in the place of a conventional film and comprising a detector array (22) disposed in the image plane and electronic circuitry associated with the detector array for still video image acquisition.
摘要:
An ultra-thin self-balancing flexible key switch for use in portable and or mobile low profile keyboards and or keypads. The key switch disclosed uses a minimal amount of components by utilizing a thin flexible polymer strip for each row of a keyboard as opposed to using separate individual keys.
摘要:
Household electrical appliance control panel (6) comprising a membrane (7) with blisters (70) defining the keys of the control panel (6) and a backing piece (8) to which the membrane (7) is attached, the backing piece (8) having openings (80) opposite said blisters (70), characterized in that the membrane (7) and the backing piece (8) are respectively made of a first and a second chemically non-metallizable material and in that the backing piece (8) comprises at least one part that is not covered by the membrane (7) and onto which a decorative piece (9) of chemically metallizable material is overmoulded, the decorative piece (9) having an external surface which is chemically metallized.
摘要:
A keypad includes a light guide panel, the interior of which light propagates through; at least one key button positioned on the upper surface of the light guide panel; and at least one reflective pattern fixedly positioned with respect to the light guide panel to reflect a part of the light, which propagates through the interior of the light guide panel, towards the key button.
摘要:
A keypad with both elevated (11) and non-elevated (22) key regions, and key switches (12) disposed beneath both types of key regions. The non-elevated key regions each provide corresponding character output based on an operation algorithm that considers activation of at least one adjacent elevated key region as well as activation of the switch below the non-elevated key region. The keypad includes a keymat (41) that is rigidly held at its perimeter in a stretched condition across a switch substrate (23). The key switches include metal snap domes (12) that have an elevated central region (212) forming a downwardly facing cavity (13) defined at its edge by a ridge (214) disposed above the switch contacts (21) that electrically engages multiple switch contacts in an annular contact zone (230).
摘要:
There is provided a switch having a flexible upper member, that is substantially electrically non-conductive, having an inner surface with an upper contact area that is electrically conductive and connected to a circuit, and a lower member that is substantially electrically non-conductive, having an inner surface with a lower contact area that is electrically conductive and connected to the circuit, wherein the upper member and the lower member are sealingly connected to form a chamber therebetween, the upper contact area and the lower contact area are separated by at least a portion of the chamber and a force applied to the upper member causes the upper contact area and the lower contact area to make contact and close the switch of the circuit.
摘要:
A push-button switch comprising a molded resin member(3), a layer (2) of plating (or a layer of evaporation) of a golden color formed on a surface of the molded resin member (3), and a colored transparent film (1a) molded on a surface of the layer (2) of plating (or a layer of evaporation) and having a desired designed color, the colored film (1a) being formed out of a moldable material, such as a resin, for example, a high molecular compound, such as PET, PC and urethane, or a complex thereof, whereby a push-button switch capable of presenting an impression of high quality owing to the metallic design, being high in a degree of freedom of designing, and preventing the occurrence of the unevenness of the color of a key top is obtained.
