ABSTRACT:
A knob assembly for the switch of a radio is provided which prevents the switch from being rotated to certain positions except when the knob is moved in an axial direction after contact with a stop. The knob may be returned to a location where other switch positions may be selected without requiring further axial motion of the knob on the part of the radio operator.
