Abstract
A key assembly for receiving devices employed in communication engineering, particularly for broadcasting and television receivers, comprises a casing provided with mutually releasable keys in the form of press buttons adapted to switch on storable, selectively adjustable electrical values supplied by channel memories including a plurality of voltage dividers for capacitance diode tuning and including, in association with the individual press buttons, rotatable and slidable knobs for channel tuning and, if desired, for selecting a given frequency range, said frequency range being adjustable by rotating the depressible and rotatable knob into any of a plurality of detented angular positions, with said depressible and rotatable knob being in a position, preferably a depressed position, different from the tuning position. Said depressible and rotatable knobs (5) are disposed in a recess (6) of said casing (3, 18) and are covered by a cover member (7; 8; 9; 34) which is slidably guided in a longitudinal direction in said casing.
