| An operating switch panel, such as for an audio equipment tuner, utilizes a metal plate which is divided into a plurality of operating parts by simultaneous etching from both sides. Connecting parts remain between individual operating parts. Thin hinges are formed on the operating parts by etching from the back surface of the metal plate, dividing each operating part into two stationary and movable parts. The stationary parts are connected to each other through the connecting parts. Display parts in the form of recesses are formed on the surface of the metal plate respectively at each operating part. Projections are formed on the back surfaces of the movable parts for engaging associated switches. A number of operating parts can be arranged close to each other in a simplified and economical manufacturing process. | ||||||
| 83 | Click disc switch assembly | US564961 | 1983-12-23 | US4539445A | 1985-09-03 | Gary D. Jabben |
| There is disclosed a click disc switch assembly comprising a plate-like base having on it electroconductive ink paths including (a) "row" paths each including a respective row of contact pads in a row-and-column matrix of such pads on the base, and (b) "column" paths corresponding to the columns of the matrix and including respective junction pads. Overlying the columns of the matrix are click disc strips secured to the rest of the assembly solely by being adhered to an overlying sheet sealing the top of the assembly. Interposed between the strips and the "row" paths is an insulating layer deposited on the base to cover portions of the row paths while leaving uncovered their junction pads. Each click disc is electrically coupled to the corresponding "column" path on the base by the coming into contact of the disc when depressed to branch segments of a further electroconductive ink path (one for each click disc strip) deposited on the insulate layer and attached through an aperture therein to the junction pad of that "column" path. Variations in the thickness of the paths on the base and on the layer are cancelled out by depositing on the base, below the click discs, pairs of bars of the same thickness as the lead portions of the paths on the base, and by raising the contact pads by an amount equal to the thickness of the paths on the layer. The base is a laminar member comprising an overlying flexible plastic sheet adhered to an underlying stiffening board. The assembly may include a tail for connecting it to other circuitry. | ||||||

| 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 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. | ||||||

Improvement of the etched surface gloss and prevention of the side etching are realized with the sulfur-contained compounds. The dust- and oil stain-resistances of the switch contacts are improved by increasing the etching depth. The switch contacts made by this invention are featured with the advantages of good reliability, good resistance to dust and oil stain, short contact bounce time, long service life, low cost of raw materials and so on. | ||||||
