ABSTRACT:
A deformable flat spring is disposed between a rotating selector knob and a stop to prevent unwanted rotation of the selector knob and wherein release of the stop requires displacement of the knob in an axial direction relative to the stop to deform the flat spring thereby permitting escape of the stop and selective rotation of the knob.
