ABSTRACT:
An illuminated rocker switch having a transparent actuator in the form of a light pipe pivoted on the switch housing. The light pipe has a set of generally parallel spaced arms each transmitting light to a separate projection surface on each arm from the common edge of an aperture illuminated by a lamp. A separate arm receives light from a separate lamp at a second light receiving surface and transmits light to a projection surface on the end of the separate arm. An opaque actuator cover is attached to the light pipe and has transparent regions adjacent each projection surface for illumination. The cover has an opaque shroud tube received on the separate arm and shields it from illumination other than from its own lamp. The light pipe carries a shorting bar which, upon user movement of the actuator switches between stationary contacts on the housing.
