Abstract: A change-over mechanism for a pushbutton radio tuner is disclosed. The mechanism has a tuning shaft which transmits rotational movement to a pinion shaft in engagement with a crown gear. The tuning shaft is slidably and rotatably mounted on a frame body. The sliding movement of the tuning shaft enables a switch to be changed-over while the rotational movement enables a tuning operation to be effected.
