Abstract
A pushbutton tuner comprising button slides disposed within a plane in parallel with a baseplate and link members operable by setting pins provided on the respective button slides also disposed within a plane in parallel with the baseplate. A memory slide is displaced by rotation of a free end of each link member when the setting pin moves rearwardly. Each of the link members is so disposed that a line drawn between its portion where it is pivotally connected to the basetable and its portion where it is pivotally engaged with the memory slide is parallel with the rearward movement of the setting pin. The link members each have symmetrically convexed engaging edges at opposite sides thereof. In the position where the link members are disposed on the baseplate so as to be close each other, the setting pins are adapted to act on the adjacent engaging edges of the link members.
