A dual band pushbutton tuner comprises a frame, a plurality of actuating members each having a pushbutton, the actuating members being capable of sliding with respect to the frame, a pair of follow-up members arranged on both sides of each actuating member, a toggle lever articulately mounted to each actuating member at a position adjacent to the pushbutton, and shift means for pivotally moving all of the toggle levers at the same time to insert the toggle levers into notches in the follow-up members on either side to couple the actuating members to the follow-up members. Means are provided for positionally fixing and maintaining the toggle lever of any actuating member in its inserted state comprising holding means constructed so that the toggle lever of each actuating member slides on the associated and uncoupled follow-up member as the actuating member is operated.
