| 1430399 Retractive switches BOWMAR INSTRUMENT CORP 20 Dec 1973 [2 Jan 1973] 59172/73 Heading H1N A keyboard switch assembly comprises pushbuttons 22 each of which actuates a resilient, conductive switch device 14 from a rest position to a deflected position in which it interconnects co-planar conductors such as 30-3, 32, Fig. 5, carried by, for example by being printed on, an insulating board 12, at least one other conductor being provided on the board spaced from and co-planar with the first-mentioned conductors and extending under the switch device but having no electrical connection therewith in either of its positions. As shown, the switch device is a snap-acting dome of, for example, square, triangular or circular shape and formed with dimples or projections 64, 66 on its periphery and at the centre thereof respectively, which form contact portions for engaging the conductors. The switching devices are located in apertures 74 in an insulating sheet 16 superimposed on the board 12 and over which is laid a flexible insulating cover sheet 18. The assembly is completed by a cover member 20 which is apertured at 76 for retention and location of the push-buttons. The latter have X-shaped projections 78 which act through the sheet 18 on the switching devices. The conductors and parts thereof which are not engaged by a particular switching device may be covered with an insulating layer (56), Fig. 7 (not shown), and the contact portions of the conductors may be plated with gold on nickel. Fig. 11 shows a modification in which an insulating sheet 82 extends between the sheet 16 and board 12 and has apertures such as 86, 88 which expose the contact portions of the conductors for engagement by the dimples 64 |

| 80 | Touch selection pad and method of manufacture | US40239 | 1987-04-20 | US4731694A | 1988-03-15 | Gunther Grabner; Dietrich Stephani |
| A touch selection pad contains a matrix of tactile sensors each of which contains a composite material with a pressure and direction-dependent electric conductivity and a dielectric material forming a capacitor. These are provided with column electrodes and row electrodes. When touched, each of the sensors creates a series circuit comprising a resistor formed of the composite material and a capacitor formed from the dielectric having a capacitance of preferably at least 50 pF. In this matrix of tactile sensors, the pressure-dependent resistance together with the associated fixed capacity serves as the measuring variable. The touch pad due to the small spacing between the sensors has a high resolution. It can be produced in a simple manner by sequentially depositing layers on a metalized carrier by means of a thin-film technique. The row and column electrodes can be etched out of a metalized plastic cover layer and a metalized carrier, respectively, by micro structuring techniques. | ||||||
