Abstract: A membrane switch has a first silver conductor formed on a flexible membrane and a second silver conductor formed on a substrate, which may also be a flexible membrane. A spacer is positioned between and adhesively secured to the substrate and membrane in such a way that there is an opening in the spacer in register with the first and second conductors. Pressure applied to the membrane moves it toward the substrate through the opening in the spacer to cause electrical contact between the first and second conductors. There are means for impeding migration of the silver between the first and second conductors which essentially consists of orienting the conductors so as to provide the longest possible path between portions thereof.

Abstract: A switch assembly includes an array of switches arranged on a substrate having a conductive pattern on a surface thereof defining a plurality of switch contacts. An apertured spacer is disposed adjacent the surface with an aperture being positioned in opposed relationship to each switch contact. A multi-conductive contact material is disposed to provide switch closure when forced through an aperture in the separator into engagement with a switch contact at a large number of separate conductive engagement regions. In one arrangement the multi-conductive contact material is a fine mesh woven wire screen stretched taut adjacent the separator while in another arrangement it is a uniaxially conducting material having a high density of parallel, spaced conductors extending perpendicular to the surface.

Abstract: In an electronic calculator essentially comprising a multidigit display, a keyboard and a data processor unit, a multidigit liquid crystal display is deposited together with integral key actuators of the keyboard on a flexible circuit film which carries electrical conductor leaves in a desired pattern. The conductor leaves to be in contact with terminals of the liquid crystal display are formed to extend in the direction of length of the liquid crystal display to thereby establish room for a battery compartment.

Abstract: A data entry pad for the entry of two-dimensional graphical data to a communication system includes a resistive grid area to which a conductive layer may be selectively contacted so that graphical data can be generated by external resistance measuring electronic circuitry. The resistive grid area is formed by a pattern of resistive inking on a base and is separated from the conductive layer by a foamed thermoplastic insulating separator. High resistance bands surround the grid area so as to linearize its output values.

Abstract: A keyboard switch assembly including a printed circuit board having four switch terminals on one side of the board, three of the terminals being arranged in a triangle and the fourth disposed within the triangle. Conductors on the one side of the board are respectively joined to the interior terminal and at least one of the three terminals. A conductive, generally triangular, snap-acting dome switch member is provided having arcuate apices, projections being respectively formed from the apices and respectively engaging the three terminals thereby spacing the periphery of the switch element from the one surface of the printed circuit board and the conductors thereon, at least the conductor connected to the interior terminal extending under the dome. The switch element has a fourth projection formed from the interior of the dome adjacent the center thereof which is in registry with the interior terminal and engages that terminal when the dome is deflected thereby completing an electrical circuit between the three terminals and the interior terminal. A layer of insulating material covers the conductors exclusive of the terminals. A sheet of insulating material covers the insulating layer and has an opening therein which receives and locates the switch member. Another sheet of insulating material covers the first sheet and the switch member. A plate covers the second insulating sheet and has an opening therein which receives a push button in registry with the switch element, depression of the push button actuating the dome of the switch member to a non-overcenter, deflected position in which the interior projection on the dome engages the interior switch terminal.

Abstract: A mechanically operated keyboard with key stations having a multiplicity of electrical switch contacts for providing an encoded electrical data output signal corresponding to and uniquely identifying individual key stations includes an array of movable contacts each corresponding to an individual key station and which are formed in a sheet of conducting material mounted above a corresponding array of fixed contacts to form multiple contact electrical switches for each key station of the keyboard. Each movable contact has a central member suspended to the sheet of conducting material in cantilevered fashion and includes a plurality of peripherally spaced contact fingers joined to the central member such that the contact fingers adjacent the junction of the central member to the conducting sheet will contact associated fixed contacts of a key station only after the remaining contact fingers have come into contact with their associated fixed contacts. An electrical circuit coupled to the contact fingers provides a strobe output signal only when all of the electrical switch contacts associated with a given key station have been actuated as indicated by the closure between the contact finger adjacent the junction of the central member to the conducting sheet and its associated fixed contact.

Abstract: A monolithic keyboard constructed in layers with inexpensive materials and which has no conventional moving parts is disclosed. In one embodiment, the layers include a bottom or first layer of conductive material, a second layer of spongy material with holes cut therein, and a third layer of flexible printed circuit. This flexible printed circuit includes a sheet of insulating material with conductive pads placed thereunder in registration with the holes in the spongy material. Key symbols are etched on or printed over the conductive pads thereby indicating the placement of the keys. Depressing the key causes contact to be made between the respective pad and the first layer of conductive material. The spongy material gives the operator the ''''touch'''' of a standard typewriter keyboard.
