ABSTRACT:
The invention includes in a unitary piece a circuit board guide and a light conduit. This unitary piece includes a guide surface defining a longitudinal channel operable to receive an edge of a circuit board which is easily guided to a connector on a backplane or motherboard. Concurrently, the light conduit is operable to transmit light from a light source to a display area. Relevant information about the system is hence transmitted from the backplane to a viewing area accessible to a user. The unitary piece is typically made of optically transmissive plastics such as polycarbonates.
