Abstract: The present invention relates to a membrane switch which is not subject to stress relaxation at contacts and is resistant to the reduction in actuating force even if the ambient temperature of the switch becomes high. A first flexible insulating substrate having a first contact pattern and a second flexible insulating substrate having a second contact pattern are disposed in facing relation via a spacer member having an opening at an area in which the first contact patterns face each other; wiring patterns conductive-connected to corresponding contact patterns are provided on at least one of the first flexible insulating substrate and the second flexible insulating substrate; and the first and second contact patterns are conductive-connected by pressure applied to a contact comprising the first and second contact patterns. The wiring patterns are conductive layers containing resin made of a mixture of conductive powder and binder resin, and a part of the second contact pattern includes a layer containing resin that is more rigid than the binder resin.

Abstract: A membrane switch assembly for mounting on a cathode ray tube is disclosed. The assembly is comprised of two layers of transparent film having spaced-apart parallel double hairline conductors deposited on the internal surfaces of both layers. The internal surfaces are separated by an insulating ultraviolet curable polymer spacer applied in parallel strips over the conductors, the spacer being discontinuous at the switch sites. The conductors cross and are normally spaced from each other at the switch sites so that when the switch is closed by applying force to bring the two layers of conductors together, the electrical circuit can be completed at any one of four locations. This ensures completion of the electrical circuit even if force has been applied at the outer edge of the switch site.

Abstract: An electronic desk-top calculator includes a bottom casing for the calculator on the inner surface of which bottom casing there are provided fixed contacts, and a flexible plate having thereon pairs of contacts provided with wiring conductors therefor. These pairs of contacts are so arranged at the positions in registry with the fixed contacts as to form a matrix. The fixed contacts act as bridging contacts and comprise electrically conductive material containing carbon particles. The pairs of contacts and wiring conductors have a first electrically conductive layer. An insulative layer of moisture-resistive material overlies the first conductive layer except those terminal ends of the wiring conductor which serve as contacts or electrical connectors. The exposed portions of the first conductive layer which function as switch contacts have an additional layer of electrically conductive material containing carbon particles.

Abstract: Membrane switch assembly comprises a transparent laminate comprised of three sheets of cellulose acetate material. The intermediate sheet has an opening therein which defines a switch site. Hairline conductors on the internal surfaces of the outer sheets cross each other at the switch site so that the switch is closed when one of the outer sheets is pressed at the switch site. The conductors are produced on the surfaces of the outer sheets by a process including electroless deposition of blanket coatings of conductive metal, selective deposition along lines which define the conductors and selective etching of the blanket coating to leave the hairline conductors.

Abstract: A switching device having a movable contact that is an integral part of a metallic support substrate and is supported above the support substrate by a plurality of spring-like support legs that are also an integral part of the support substrate. The support legs extend radially outward from the movable contact and contact the substrate and the movable contact at equally spaced points. The movable contact is aligned with either a stationary contact or another movable contact and a stationary contact to provide either single or multiple switching. The switching device can be used for contact switching or capacitive switching. A plurality of the switching devices can be formed on the support substrate making the switching device particularly well suited for use in a keyboard. A portion of each support leg may be thinned to provide a negative force-displacement characteristic which provides a good tactile feedback signal indicating switching.One or more of the switching devices are produced by forming one or more groups of curved, unconnected, radially extending slots in a metallic substrate, deforming the legs defined by the slots past their elastic limit, and then, if desired, precipitation hardening the completed structure. To assure movement of the central area of the movable contact past the plane of the support substrate, a portion of each of the legs is thinned prior to the legs being plastically deformed.

Abstract: Relates generally to the production of electrical signals from a keyboard, each key of which is individually operatively associated with a switching device whose activation to electrical conductive condition is controlled by the displacement of the key. These switches are hermetically sealed from the atmosphere and are electrically scanned in succession at relatively high speeds and at a repetitious rate such that several scanning cycles occur during the normal activation of a selected key. The keyboard mechanism also includes a shift register having one more bit position than the number of switch devices and into which a bit is introduced into the ''''one'''' position at the instant the scan encounters a closed switch of the keyboard. This bit is then shifted through the register in timed relation to the scan of the remaining key switches and unloaded into the last bit position of the register. A detector senses the presence of a bit in both the ''''one'''' position and the last position of the shift register and upon detection of a bit solely in the one position it delivers a signal indicative of the character represented by the actuated key and upon detecting bits in the two extreme positions of the shift register it nullifies the delivery of such a signal.
