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.
