Abstract: A pushbutton tuner has a plurality of presettable pushbutton actuator assemblies. Each of the pushbutton actuator assemblies comprises a slide mounted on a support so as to be movable between a forward inoperative position and a rearward operative position and normally biased into the inoperative position, a control member pivotally mounted on the slide and having an upstanding pin mounted thereon and being adjustable positionable relative to the slide, a preset member for releasably locking the control member to the slide, and a pushbutton carried by the preset member and having a forward end of the slide slidably received therein. The pushbutton actuator assemblies are disposed in a direction transverse to a movable part of a tuning element.

Abstract: An interconnecting member which operatively connects a pushbutton slide with either one of a pair of tuning slides selectively is carried by shift means which moves it from one of its operational positions to the other. When a selected tuning slide reciprocates within a stationary guide channel together with the pushbutton slide, the interconnecting member moves over the shift means concurrently.
