ABSTRACT:
The selector switch has two operating positions, indicated by different colors of light. An operator knob having two spaced translucent portions of different colors is drivingly connected to a tubular switch operator rotor. A lamp shield is received within the rotor around a lamp. The lamp shield has an aperture which directs light only through the translucent portion of the selector switch knob directly over the aperture so that the color of the visible light corresponds to a particular operating position of the selector switch knob.
