The keyboard housing has a recess on the cover equipped in which differently strong keyboards as well Membrane keyboards with circuit board can be used and these differently strong keyboards by one in the Height of recessed positioning plate (cover bracket) be balanced.

In der Vertiefung sind als Rastmittel Einrastrillen vorgesehen, und die Positionierplatte hat randseitig jeweils mindestens eine Verzahnung als Rastmittel und greift höhenverstellbar in die Einrastrillen des Tastaturgehäuses ein. Dabei kann diese einen Abdeckträger bildende Positionierplatte einen Tastatureinsatz mit Drucktasten oder einen Einsatz mit Silikontastatur überdecken und dabei gibt sie durch ausbrechbare Plattenteile die Drucktasten zur Bedienung frei. Weiterhin kann auf den eingesetzten Abdeckträger eine Folientastatur aufgebracht werden.In the recess, snap-in grooves are provided as locking means, and the positioning plate has at least one on the edge Interlocking as a locking device and reaches into the adjustable height The keyboard housing. This can be one Positioning plate forming cover support with a keyboard insert Cover push buttons or an insert with a silicone keyboard and in doing so, it releases the pushbuttons through break-out plate parts Operation free. Furthermore, the cover carrier used a membrane keyboard can be applied.

Die jeweils in die Vertiefung eingesetzten Tastaturen werden durch die einfach aufgebaute und kostengünstig herstellbare sowie leicht zu handhabende Positionierplatte sicher lagefixiert gehalten. The keyboards used in the recess are shown by the simply constructed and inexpensive to manufacture as well as light Positioning plate to be handled held securely in position.
