ABSTRACT:
The pushbutton tuner comprises a plurality of pushbutton assemblies arranged side by side and parallel to each other. Each pushbutton assembly is movable in its longitudinal direction towards and away from a control bar slidably arranged transversely with respect to the pushbutton assemblies and operatively connected with the tuner group of the radio set. The improvement resides in the fact that the transverse control bar carries an abutment pin for each pushbutton assembly, while each pushbutton assembly carries a V-shaped notch presenting two inclined edges which are intended to cooperate with the respective abutment pin provided on the transverse control bar. In this manner, whenever a pushbutton assembly is pushed for the selection of the desired frequency associated thereto, one of the inclined edges of the V-shaped notch will abut against the respective abutment pin on the transverse control bar, and promote its shifting in longitudinal direction, until the other one of the inclined edges of the V-shaped notch also abuts against the abutment pin.
