    Abstract: Relates generally to the production of electricial signals from a keyboard, each key of which is individually operatively associated with a switching device whose activation to electrical conductive condition is controlled by the displacement of the key. These switches are hermetically sealed from the atmosphere and are electrically scanned in succession at relatively high speeds and at a repetitious rate such that several scanning cycles occur during the normal activation of a selected key. The keyboard mechanism also includes a shift register having one more bit position than the number of switch devices and into which a bit is introduced into the ''''one'''' position at the instant the scan encounters a closed switch of the keyboard. This bit is then shifted through the register in timed relation to the scan of the remaining key switches and unloaded into the last bit position of the register. A detector senses the presence of a bit in both the ''''one'''' position and the last position of the shift register and upon detection of a bit solely in the one position it delivers a signal indicative of the character represented by the actuated key and upon detecting bits in the two extreme positions of the shift register it nullifies the delivery of such a signal.

    Abstract: Rechteckförmiger Kontaktträger (1) für Tastaturen mit den einzelnen Tasten zugeordneten, aus einander gegenüberliegenden Kontaktbahnen (3, 4) aufgebauten Kontaktfeldern (2).
    Die die Kontaktstellen bildenden Kontaktbahnen (3, 4) sollen so gestaltet werden, daß bei der Herstellung des Kontaktträgers (1) im Siebdruckverfahren auch bei Auftreten von Fertigungstoleranzen die Ausschußrate gering gehalten wird.
    Dies wird dadurch erreicht, daß - bezogen auf einen Randbereich des Kontaktträgers (1) die Kontaktbahnen (3, 4) im Kontaktbereich parallel und unter einem Winkel von 45° zueinander angeordnet sind. Dadurch wird der Abstand der Kontaktbahnen (3, 4) im Kontaktbereich erheblich vergrößert, ohne daß die Abmessungen des Kontaktfeldes (2) geändert werden.

    Abstract: @ A membrane switch panel has a printed circuit base board (20) carrying bare copper electrical circuitry (26) and contacts (26 & 28). A flexible, non-elastomer, laminar membrane (22) overlays the board (20) and also carries a bare-copper contact (24). An electrically insulating spacer (3) is provided between the board (20) and the membrane, but it is provided with an opening to allow the contact (24) upon local depression of the membrane to bridge the contacts (26 & 28) in the base board (20).
    The membrane (22) is adhesively sealed to the base board (20) enclosing an atmosphere of limited tarnishing ability for the contacts (20, 26 & 28) to maintain a low contact resistance and allow non-precious metals to be used for contacts.
