ABSTRACT:
A dual band pushbutton tuner is disclosed having a pair of tuning slide assemblies disposed on the opposite sides of a pushbutton slide and which can be selectively actuated in conjunction with an operation of the pushbutton slide, without using a shuttle. Each of the tuning slide assemblies is normally connected with the pushbutton slide through connection means, which is constructed such that when one of the tuning slide assemblies is constrained by constraining means, the other tuning slide assembly is permitted to move in response to an operation of the pushbutton slide. The pair of tuning slide assemblies alternately assume this manner of operation as the constraining means is switched.
