摘要： The present invention provides low cost electrical switch assemblies and methods for manufacturing same. The switch assembly comprises an array of resiliently flexible metallic conductors arranged in predetermined circuit pathways on a dielectric carrier panel. A plurality of apertures or cavities are provided at predetermined locations in the carrier panel. The switch contacts comprise a pair of generally L-shaped fingers which are integral extensions of the flexible conductors. The fingers extend from opposite edge surfaces of the carrier panel defining an associated aperture or cavity, to pass one another over or within their associated aperture or cavity, with the free ends of the fingers terminating adjacent one another. The free ends of the L-shaped fingers extend in part above or below the plane of the carrier panel, and are positioned in spaced relationship to one another so that the conductors they connect are normally open, but are sufficiently close to one another so that slight deflection of the fingers from their normal orientation moves the free ends in contact with each other to thereby close the switch. Alternatively, the free ends of the L-shaped fingers are positioned in contact with one another so that slight deflection of the fingers from their normal orientation breaks their contact. The metallic conductors and integral switch contacts may be formed by photoimaging and either chemical milling or additive techniques such as plating up or solder doming, and/or mechanical milling and/or precision die stamping techniques.

摘要： 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.

摘要： A pressure responsive, variable resistance, analog switch has first and second conductors interleaved in spaced-apart relationship and disposed on a base member. An insulative spacer ring is positioned around and rises above the first and second conductors. A resilient cover sheet is attached to the top of the insulative spacer ring in spaced relationship over the conductors to define an enclosure between the resilient cover sheet and the base member. A pressure sensitive resistive conductor composition is disposed on the resilient cover sheet or on the conductors in the enclosure to interconnect a resistance between the first and second conductors when the resilient cover sheet is depressed against the conductors. The amount of resistance so interconnected varies inversely to the amount of pressure exerted.
