Abstract: A keyboard membrane switch including the standard three layer resilient flexible diaphragm switch construction. Threshold pressure is applied to the membrane prior to engagement of the membrane contact with at least one fixed contact. This phenomenon is achieved by applying variable thicknesses of nonconductive threshold paint or glass to the substrate, flexible membrane, a first layer of threshold material or any combination thereof.

Abstract: A membrane switch in which a membrane layer is supported in a spaced relation from at least one contact of one or more pairs of electrically conductive switch contacts. The contacts are mounted on an insulated substrate. The membrane surface adjacent the contacts has an electrically conductive bridging surface supported thereon such that depression of the membrane will bridge the contacts to complete a circuit. The membrane is mounted on the substrate and is held in a normally spaced relationship with the contacts by a plurality of projections formed on the membrane surface adjacent the substrate or one or more of the contact surfaces. The projections may be integrally formed by puncturing the membrane surface with a sharp object or projections may be formed by permanently deforming the membrane without rupturing the membrane itself. Additionally, the projections may be formed by applying individual spacer elements to the membrane surface.

Abstract: Membrane keyboard apparatus is disclosed including an insulator having a conductive sheet thereon providing a plurality of first electrode members in the form of an array of apertures, and a plurality of second electrode members located concentrically within and spaced from the periphery of the apertures of the first electrodes to form an array of individual switching units. The height of the conductive sheet is greater than the height of the second electrode members whereby the level of the top surfaces of the plurality of first electrode members is vertically spaced above the level of the top surfaces of the second electrode members. A flexible, conductive member is disposed in a spaced relation above and adjacent to the level of the top surfaces of the pluralities of first and second electrode members. An identification member having an array of indicia corresponding to the array of individual switching units is disposed in a spaced relation above and adjacent to the flexible conductor. A threshold member is included in the form of an array of elastic bubble members corresponding to the array of individual switching units and including air escape means for the bubble members to avoid problems with trapped air. The bubble members are actuable by the touch which causes the selected bubble member to be deflected into the flexible conductive member to provide a conductive path between the associated first and second electrode members of the underlying switching units.
