Abstract of the Disclosure Membrane keyboard apparatus is disclosed as including an insulator having a conductive sheet thereon providing a plurality of first electrode members and a plurality of second electrode members to form an array of individual switching units. A membrane member is disposed in a spaced relation above and adjacent to the level of the top surfaces of the plurali- ties of first and second electrode members. The membrane member is formed of a flexible, plastic, insulative sheet member, and includes: an array of indicia corresponding to the array of individual switching units formed on the first, bottom surface of the sheet member; a background color layer formed on the bottom surface of the sheet member and over the array of indicia; a very thin, conductive layer formed on the background color layer and applied to form patterned areas for providing a conductive path between the first and second electrode members of the individual switching units selected; and height differential members formed in the membrane member. e height differential members formed in the membrane member have a first, actuated position where the conductive layer provides a conductive path be- tween the associated first and second electrode members of the actuated individual switching unit and a second, nonactuated, normal position where the conductive layer is electrically spaced from at least the second elec- trode members to electrically insulate the first electrode members and the second electrode members.
