ABSTRACT:
In a pushbutton tuner in which a tuning carriage is designed to be laterally positioned by a selected one of a plurality of carriage levers which are designed to slip with respect to the carriage as the carriage is moved, a reduced degree of force is required for moving the carriage by making the levers normally loosely associated with the carriage so that relative motion between them involves little or no friction, but in which the carriage lever operative at any given time to position the carriage is urged into snug engagement with the carriage thereby to eliminate backlash and achieve high accuracy tuning.
