| A keyboard assembly includes an insulative substrate upon which are carried a plurality of conductive paths. Respective portions of the paths are selectively bridged upon depression of a dome-shaped conductive resilient contact element. A pair of space-opposed regions of the dome's marginal portion are deformed downwardly away from its apex so as to constitute a pair of space-opposed feet. The feet have a complex shape which leads to high lifetime of the dome. Preferably, the feet rest on corresponding conductive pads, and the pad pairs for adjacent domes may be differently oriented so as better to accommodate the passage of leads between those domes. Leads on the substrate passing beneath dome edges desirably are depressed into the substrate. Overlying the domes in a completed assembly is a layer of deflectable insulating material that is adhesively affixed to the substrate and to the domes; the latter includes an aperture in registry with each dome but of a diameter smaller than the width of such dome. Advantageously, the adhesively-coated layer also is utilized for the purpose of picking up individual domes from a magazine and transferring them to their assigned positions on the substrate. | ||||||

| 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 pluralities 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. The height differential members formed in the membrane member have a first, actuated position where the conductive layer provides a conductive path between 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 electrode members to electrically insulate the first electrode members and the second electrode members. | ||||||
| 173 | Keyboard switch assembly having raised contacts supported by helicline legs on a common conductive sheet | US508482 | 1974-09-23 | US3979568A | 1976-09-07 | Wendell C. Johnson |
| A switching device having a movable contact that is an integral part of a metallic support substrate and is supported above the support substrate by a plurality of spring-like support legs that are also an integral part of the support substrate. The support legs extend radially outward from the movable contact and contact the substrate and the movable contact at equally spaced points. The movable contact is aligned with either a stationary contact or another movable contact and a stationary contact to provide either single or multiple switching. The switching device can be used for contact switching or capacitive switching. A plurality of the switching devices can be formed on the support substrate making the switching device particularly well suited for use in a keyboard. A portion of each support leg may be thinned to provide a negative force-displacement characteristic which provides a good tactile feedback signal indicating switching.One or more of the switching devices are produced by forming one or more groups of curved, unconnected, radially extending slots in a metallic substrate, deforming the legs defined by the slots past their elastic limit, and then, if desired, precipitation hardening the completed structure. To assure movement of the central area of the movable contact past the plane of the support substrate, a portion of each of the legs is thinned prior to the legs being plastically deformed. | ||||||
