Abstract
An apparatus (10) comprises a manually rotatable knob (14) and a source (18) of light. The knob (14) has an axis (15) of rotation, and has a discrete light-transmitting portion (40) which is spaced from the axis (15). A hollow part (36) of the knob (14) defines a chamber (39) extending from the axis (15) to the light-transmitting portion (40). A rotor (22) extends along the axis (15) from the chamber (39) to the source (18) of light. The rotor (22) is formed of material which is translucent sufficiently to transmit light from the source (18) to the chamber (39) to flood the chamber (39) with light, and thereby to illuminate the light-transmitting portion (40) of the knob (14).
