Abstract: A pushbutton system for a car radio receiver, comprising pairs of selector drive rods alternately engaged by a common button. A pawl drives a sequencing catch. The pivot point of the pawl is shifted when re-setting a drive rod so that sequencing is inhibited. The pivot point is restored to normal only upon full depression of the button.
