| 3 | Membrane switch with means for preventing silver migration | US447129 | 1982-12-06 | US4458969A | 1984-07-10 | Gregory Demeo |
| In a membrane switch having at least one silver conductive lead terminating at a termination point for connection to an electrical connector, the improvement comprising a strip of non-migrating, conductive material applied over said conductive lead at least in a region adjacent to said termination point and extending a distance beyond the termination point of said conductive lead for receipt of said electrical connector affixed to and in electrical contact with said strip of non-migrating, conductive material at the extended portion thereof. | ||||||
| 4 | Encoded keyboard switch | US502369 | 1983-06-08 | US4450324A | 1984-05-22 | Kazutoyo Fukukura; Richard A. Martinez |
| Encoded keyboard switch comprises a single sheet of flexible film which has switch electrodes and circuit conductors applied to one surface. The sheet of film is folded to form four sections. After folding, the switch electrodes of the two upper sections are opposed to each other and the electrodes of the remaining two sections are opposed to each other so that when the folded film is pressed at a switch site, the two switches formed by the opposed electrodes are sequentially closed. The switch electrodes are interconnected in accordance with an improved encoding scheme which results in a reduced requirement in the number of circuit conductors, the elimination of some switch electrodes, and other advantages. | ||||||
| 5 | Key-operated switch and an assemblage of such switches for electronic desk calculators or the like | US932326 | 1978-08-09 | US4207443A | 1980-06-10 | Yasuo Matsuura |
| An assemblage of hand-operated switches includes a plurality of printed fixed contact sets on an insulating base. A spacer sheet overlying the insulating base has openings therein in register with the fixed contact sets. Further overlying the spacer sheet is a plastic film having printed movable contacts formed thereon in register with the spacer sheet openings. Each switch is equipped with a key or button, upon depression of which the corresponding movable contact is moved into engagement with the corresponding fixed contact set through the corresponding spacer sheet opening. The plastic film together with the printed movable contacts thereon can be replaced by a single piece of resilient sheet metal. | ||||||
| 6 | Keyboard switch covering pads | US96513 | 1979-11-21 | US4289940A | 1981-09-15 | Ryoichi Sado; Yoshitusgu Morikawa |
| A novel keyboard switch covering pad suitable for use in, for example, a pocketable electronic calculator is proposed which is safe from the danger of failure or erroneous operation of the LSI or other electronic devices built in the instrument when two or more of the key switches are pushed simultaneously.The keyboard switch covering pad of the invention comprises an electrically conductive rubber sheet divided into a desired number of sections and an electrically insulating sheet which serves as a common lining for the divided sections of the rubber sheet, on which the divided sections are bonded keeping an electrically insulating air gap space between each other. | ||||||
| 7 | High density programming means for programmable sewing machine | US879338 | 1978-02-21 | US4154178A | 1979-05-15 | Jack Brown; John A. Herr; Nicholas A. Tarquinio |
| An operator manipulating means for a programable electronically controlled sewing machine. The operator manipulating means provides an array of switch points, each related in a row, to discrete needle positions attainable by the electronically controlled sewing machine; and in a column, to the least feed increment attainable thereby. The switch array is fabricated using a pair of printed circuits, one of which must be flexible and each having spaced, parallel conductors, and arranged with respect to each other so that the conductors of one are substantially perpendicular to the conductors of the other and are in facing relationship. The printed circuits are separated in a first embodiment by a pair of insulating sheets, each having an array of apertures in spaced registry with each other and aligned in rows and columns with the conductors on the printed circuits. The pair of insulating sheets are separated by a flexible conducting sheets which may be used as a common conductor. Depression of a conductor on the flexible printed circuit through an aperture of an insulating sheet will establish a connection to the flexible conducting sheet, which conducting sheet will be deflected through the aperture in spaced registry to establish a connection with a conductor of the other printed circuit. | ||||||

| A universal printed circuit pattern of conductors for use in connection with diaphragm-type push button electrical switch panels which allows the printed circuit board to be physically sheared along plural axes to accommodate switch panels of varying sizes without destroying electrical continuity of the ground or common conductor thereon. | ||||||
| 9 | Pressure sensitive switch structure | US107970 | 1979-12-28 | US4296406A | 1981-10-20 | Billy J. Pearson |
| The present invention switch comprises a pair of electrodes separated by resilient resistive material which changes resistance several orders of magnitude in response to light pressure. Sensing and amplifying means are provided to detect a predetermined change in resistance. An array of a plurality of such switches may be arranged in a switching matrix to provide any desired form of switch controls or a keyboard for numerous electronic applications. | ||||||
| 10 | Keyboard membrane switch having threshold force structure | US613254 | 1975-09-15 | US4017697A | 1977-04-12 | Willis August Larson |
| 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. | ||||||
