Abstract: A keyboard for a computer includes a bottom board arranged to contain keys, and a sealing layer adhered to the lower surface of the bottom board; wherein the sealing layer is installed with a dividing structure consisted of at least one or more grooves, slits or apertures. The dividing structure is used for breaking up the totality of the sealing layer, so that when the bottom board and the sealing layer are to be adhered integrally via the baking procedure, the condition of distortion therebetween caused by the different thermal expansion coefficients of the two materials due to temperature change is to be prevented, so as to maintain the smoothness of the keyboard, and expedite the assembly process.

Abstract: The thin section data display control panel of the present invention includes a graphic overlay, a diffuser block affixed to the graphic overlay and light emitting diodes surface mounted on a printed circuit board for providing localized sources of light to be transmitted through the diffuser block to the overlay. The graphic overlay is generally opaque, but has translucent areas through which the illumination shines. An overlay reflective portion on a diffuser side of the overlay reflects light back into the diffuser, except in areas adjacent to the translucent areas of the overlay. The diffuser block is affixed to the graphic overlay and is generally transparent for transmitting the light from the light emitting diodes. Block reflective surfaces on the perimeter edges of the diffuser block prevent light from exiting through the edges. Matte surfaces of the diffuser block adjacent the graphic overlay and adjacent the printed circuit board scatter the light transmitted from the light emitting diodes. The light emitting diodes provide a plurality of localized sources of light which is scattered within the diffuser block and thereby provide relatively uniform back lighted illumination to the translucent portions of the graphic overlay. The light emitting diodes are partially received within a recessed portion of the diffuser block. An electrostatic discharge shield, adjacent the printed circuit board, having a reflective metallic surface reflects light not transmitted through the translucent portions back into the diffuser block.

Abstract: A switch designed to be activated by touch contact has a switching chamberith contact surfaces on opposite sides thereof. A flexible switching film carries one of the contact surfaces and is arched over one side of the chamber. In order to prevent an increase in length of the switching film due to climatic effects from leading to incorrect switching, the switching film has at least one punctiform or linear deformation placed so as to cause the film to arch away from the opposite side of the chamber.

Abstract: Disclosed is a data entry keyboard which has a multitude of depressible keys which are selectively depressed for the entry of predetermined data. In the keyboard, an insulating member is sandwiched between a first substrate having stationary electrodes and a flexible second substrate having movable electrodes. The stationary and movable electrodes face one another through apertures formed in the insulating member. Upper and lower marginal surface portions of the insulating member, including the respective peripheral edges of the apertures, are kept parallel to the first and second substrates corresponding thereto by a plurality of protuberances on the substrates so that voids with a predetermined width are left between the marginal surface portions and the individual substrates. The movable electrodes of the second substrate are electrically fixed, in the form of a cantilever each, to the extreme end portions of branch conductor strips which diverge from a main conductor strip at right angles thereto. When one of the keys is depressed, the second substrate is deformed to narrow the corresponding void, thus bringing the corresponding movable and stationary electrodes into contact with each other.

Abstract: A custom prototype membrane switch panel, kit, and method for construction. Two membranes, an insulative spacer for use therebetween, and a plurality of conductive elements disposable between each membrane and spacer are provided. Spacer apertures in registry with the elements permit electrical contact therebetween upon displacement of one membrane toward the other. The elements are comprised of conductive ink bonded to an insulated backing in any desired geometric shape or shapes, and may be provided individually or plurally in sheet form separable therefrom for disposition between the spacer and membranes. Elements of different colors facilitate tracing different conductive paths created thereby in the resultant switch panel, and the backing automatically electrically insulates crossovers between the elements. One or more of the membranes or spacer has features, alone or in combination, of transparency, having a graphic grid network superimposed thereon, or being hingable to one or more remaining membrane or spacer, facilitating aforementioned registration.
