摘要:
A keyboard switch includes a lower-electrode insulating sheet provided with an electrode pattern formed by arranging lower electrodes at given distances, each of the lower electrodes being composed of a pair of electrodes having interfitted teeth; and an upper-electrode insulating sheet provided with an electrode pattern formed by arranging a plurality of lines of rectangular upper electrodes so that each of the rectangular upper electrodes crosses the corresponding pair of teeth of the electrodes of the lower electrodes at right angles.

A multidirectional control switch which comprises at least a control means (1) arranged to be movable, a base (2), and first and second contact means in connection with the control means (1) and/or the base (2), one of the contact means being a coupling means (4). One of said contact means is a contact surface (2) comprising several contact areas (3), and the first contact means (2, 4) is arranged in connection with the control means (1), and the second contact means is arranged in connection with the base (2), and at least one of said contact means (2, 4) is flexible, and the coupling means (4) is arranged to touch the contact surface (2) in one or more contact areas (3) to generate a control signal, wherein a contact area is arranged to be formed at the point of contact between the base and the coupling means. The invention also relates to a method for forming a control signal by a multidirectional control switch, as well as to a program implementing the method, and a software product.

A programmable electrical switch having a housing and a plurality of single-switch-position conducting leads which are positioned in two substantially aligned rows is disclosed. Each of the leads has a proximal end that is disposed within the housing and a distal end that extends outwardly from the housing. The leads are disposed in the housing so that they are electrically independent of one another. The switch may also have a conducting bridge electrically interconnecting the leads in each of the rows. The switch also includes a moveable conductive contact that is positioned between a pair of opposing leads to electrically bridge a gap between the opposing leads.

摘要:
A method and apparatus for constructing assemblies for keypads with different key layouts using substrates each having the same pattern of electrical-contact regions formed thereon and domed contact elements. In the invention, a first design of key layouts is selected, a first insulating layer having a plurality of apertures dependent on the first design are provided, and the domed contact elements are mounted to confront corresponding electrical-contact regions of a first of the substrates with the first insulating layer disposed therebetween. Each of the apertures are in register with the domed contact element to thereby produce an assembly having the first design of a key layout. Further, in the invention a second design of a key layout is selected, where the second design of a key layout is different from the first design of a key layout, a second insulating layer having a plurality of apertures dependent on the second design of a key layout is provided; and the domed contact elements are mounted to confront corresponding electrical-contact regions of a second of the substrates with the second insulating layer disposed therebetween. Each of the apertures are in register with a domed contact element to thereby produce an assembly having the second design of a key layout.
摘要:
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.
