Abstract
The combination of a light pipe and a face plate having an opening to receive the light pipe. The light pipe and the face plate opening are formed with complementary polarizing features so that the light pipe can only be inserted into the opening with a predetermined angular orientation about its axis. After insertion into the opening, the light pipe is rotated about its axis to lock it in place. The face plate may then be secured to the edge of a circuit board with the light pipe in alignment to receive light emitted from an indicator light source mounted to the circuit board.
