    摘要： Eine Eingabetastenanordnung für ein elektronisches oder elektrisches Gerät (12) umfaßt wenigstens eine Taste (2,3,4,6,7,8,11), die zwischen einer Ruhestellung und einer Betätigungsstellung bewegbar ist, einen durch Bewegen der Taste zwischen einem geschlossenen und einem offenen Zustand umschaltbaren Schaltkontakt und eine Verwaltungsschaltung (13,14,15) zum Überwachen von Bewegungen der Taste und zum Ausgeben eines die Ergebnisse der Überwachung anzeigenden Ergebnissignals an das elektronische oder elektrische Gerät (12). Die Verwaltungsschaltung liefert kein solches Ergebnissignal, solange der Zustand des Schaltkontakts unverändert bleibt oder von seinem der betätigten Taste zugeordneten Zustand in den der unbetätigten Taste zugeordneten Zustand übergeht. Ein solches Signal wird nur geliefert, wenn der Schaltkontakt von seinein der unbetätigten Taste zugeordneten Zustand in den der betätigten Taste zugeordneten Zustand übergeht.

    摘要： In a keyboard arrangement and method for identifying a pressed key according to the present invention, conductor lines (4', 6') at each key (B), which may be connected together, are connected to a ground plane (24, 23, 27) as a response to a pressing (P) of a key. The pressed key (B) is identified by detecting the conductor lines that are connected to the ground plane. All the conductor lines may be connected as pulled-up inputs of a detector circuit, and any conductor line or combination of conductor lines may be used to identify a key. A noticeably greater number of keys may be simply identified with the same number of conductor lines than is possible in a solution according to the prior art. In an advantageous embodiment of the present invention, the means for connecting the conductor lines (4', 5', 6', 7') to the ground plane (27) is a conductive plate (23), which essentially covers the whole keyboard. This also provides a good shield against electrostatic discharges and other interference.

    摘要： A switch arrangement is disclosed. The arrangement comprises a number of switches arranged on a substrate, each switch having a resiliently deformable conductive dome for making an electrical connection with a corresponding contact on the substrate; and a number of signal lines for connection to a microprocessor for signalling an operation of a switch. The switches are arranged such that operation of any given switch creates a unique electrical connection between two of the signal lines and each of the signal lines is electrically connected to a conductive surface of a respective dome. Also disclosed is a cover for a portable electronic apparatus, having a number of user operable keys. The keys are connectable to a microprocessor in the apparatus via electrical connections made using the conductive domes.

    摘要： A membrane switch assembly (10) is comprised of spaced apart layers (12, 16) having corresponding patterns of conductive switch contacts (28, 28') arranged in series thereon, the layers (12, 16) being separated by spacing means (20) having openings therein. The switch contacts (28, 28') on each layer are spaced along a single conductive path (24, 24') so that a regular unit value of impedance means exists between the switch contacts (28,28'). When the electrical circuit is completed by closing a switch site, the resulting total impedance is essentially equal to the sum of the unit values of the impedance means along the circuit path formed by the closed switch.
