Abstract

  • 2.1 Diese Tasten werden häufig von den unbeweglich angeordneten Tastenteilen abgehoben und so wieder aufgesetzt, daß ein anderer Kontakt betätigt wird. Hierbei kann durch Fehlbedienung der Eintrittsbereich der Führungsschlitze verformt und die gesamte Einrichtung unbrauchbar werden.
  • 2.2 Hiergegen sieht die neue Einrichtung vor, daß die Scherenarme 7, deren Führungszapfen 8 in den Führungsschlitzen 10 der festen unbeweglichen Tastenteile 6 gelagert sind, federnd ausgeführt sind und durch schräge Flächen 11 an den Führungszapfenstirnwänden, die sich beim Einsetzen an Führungsschlitzwänden 12 abstützen, einfedern, bis die Zapfen 8 in die Schlitze 10 einrasten.
  • 2.3 Mit der neuen Einrichtung wird eine Verformung des Führungsschlitzes vermieden und zusätzlich eine erleichterte Montage möglich.
