ABSTRACT:
An electronic instrument has a rotary switch with an extending shaft, a light source proximate to the shaft, and a knob attached to the shaft. The knob has a body with a rear face, an opposed front face, and side surfaces extending between the faces. The rear face defines a bore sized to receive a free end of the shaft. The body has a light-transmissive portion extending from a first surface portion of the rear face surrounding the bore, such that light from the light source enters the light transmissive portion regardless of the rotary position of the knob. The light-transmissive portion of the body extends to a window in the side surface or the front face.
