Abstract: A switch for electrically connecting a first terminal with a plurality of other terminals. A contact movable into and out of electrical engagement with a plurality of base contacts is employed. The movable contact may comprise physically parallel wires affixed to a flexible plate, as well as wires which radiate radially outwardly from a point. The physically parallel wires may be inclined to the base contacts or the base contacts may be of different thicknesses to achieve sequential contacting of the base contacts by the movable contact. The base contacts may be any convenient shape, or in the form of concentric spirals or interspersed parallel segments or adjacent triangular-shaped segments.

Abstract: A faceplate is provided with a plurality of openings therein, each representing a digit to be used in a keyboard; a metal switch plate is positioned immediately beneath the faceplate and includes a plurality of dome-shaped resilient deformable dimples forming keys therein, each registering with and extending into a different one of said openings. An insulating plate, with holes therein registering with the dimples, separates the switch plate from a contact board that includes a plurality of contact buttons, each registering with one of the holes in the insulating plate. The dimples may be depressed by the fingertip of an operator to ''''snap'''' into contact with a corresponding contact button and will ''''snap'''' back to their original position when fingertip pressure is released.

Abstract: A signal-actuating device having its major component parts molded as a single piece. The actuating device includes a single body composed of an elastomeric material which is a glycol cured isocyanate terminated polyester formulated to be virtually a true gel, character symbols bonded on the body representing key positions and Mylar circuitry strips of etched copper wires bonded to raised projections located on the underside of the body. Contact made by depressing a key gives a binary-coded output, as well as providing a signal for activating distant devices.

Abstract: An electrically conductive membrane pressure switch, such as a graphene membrane pressure switch. The electrically conductive membrane pressure switch includes an electrically conductive membrane, source, drain plane, actuator, and movable element (such as a piston element). The actuator drives the movable element to create a pressure differential that moves the suspended section of the electrically conductive membrane between its on, off, and neutral states.
