| 1 | Keyswitch with telescoping plunger | US418674 | 1982-09-15 | US4454562A | 1984-06-12 | Robert D. Bush; Dean S. Cowles |
| A low profile keyswitch utilizes a telescoping plunger assembly. A linear feel and overtravel are achieved. The telescoping plunger assembly includes an outer plunger shaft and an inner plunger shaft slideably mounted therewithin for telescopic extension therefrom. A retaining member locks one end of the inner plunger shaft within the outer plunger shaft, thereby defining the maximum extension of the inner plunger. A spring biases the inner plunger into its fully extended position. | ||||||
| 2 | Flexible diaphragm keypad and method of manufacture | US683892 | 1984-12-20 | US4609791A | 1986-09-02 | Jean-Pierre Abbat |
| A keypad is formed of a set of transparent buttons slidably located within apertures of a grid. The grid has sidewalls for engagement with the base of a printed circuit board. Switch assemblies are provided by conductive elastomeric domes formed of a single sheet of elastomeric material disposed between the printed circuit board and the buttons. Integrally formed within a concave side of each dome is a contact region driven by a displacement of a button towards the printed cirucit board. An insulating layer above strip conductors of the circuit board is perforated at sites of the switches to allow the contact region to touch the exposed portions of the conductors to complete an electrical circuit. A dome deforms with springiness which urges the dome back to its original shape upon release of a button by a user of the keypad. Manufacture of the keypad is facilitated by construction of a set of the butons on a webbing which maintains alignment of the buttons as they are secured to the respective domes. The webbing is later removed to permit insertion of the buttons into apertures of the grid. | ||||||
| 3 | Keyboard design | US599801 | 1984-04-13 | US4536625A | 1985-08-20 | Alain M. Bebie |
| Electrical switch keyboards comprise a one-piece mat made of resilient material laid in sealing engagement upon a frame within which switching elements are positioned to operate in conjunction with key portions of the mat. The mat is the uppermost layer of the keyboard and comprises the key portions connected by integral spring portions to frame positioning portions. Operation elements carried on integral extensions depending from the key portions of the mat function with the switching elements in the frame to produce switching currents upon actuation of the key portions. | ||||||

Um Tastaturfelder mit einer einteiligen gummielastischen Matte, auf einer Trägeranordnung mit tastenbetätigten Schaltorganen verschmutzungsunanfällig und bequem reinigbar, auszugestalten, umfasst die Anordnung als abschliessende Abdeckung derTrägeranordnung (14,16) die gummielastische Matte. Dabei umfasst die Matte Tastenbereiche und Auflagebereiche (11, 15), die durch Federbrükken-Mattenpartien verbunden sind, derart dass zum Rückholen der Tasten keine zusätzlichen Federorgane vorgesehen werden müssen und/oder es sind trägeranordnungsseitig Bewegungsführungen (16) für Tastenbereiche (11) der Matte vorgesehen, um eindeutige Schaltbewegungsbahnen für die Tastenbereiche (11) festzulegen. |
