Abstract: Various exemplary embodiments relate to a light transmission device for transmitting light from at least one light source to an illuminated surface. The device may include at least one light entrance surface that allows entrance of light from the at least one light source; a light emitting surface with an area greater than the total area of the at least one light entrance surface; at least one light pipe portion extending from the at least one light entrance surface toward the illuminated surface wherein the light pipe portion internally reflects the light toward the illuminated surface; and a flared diffusion portion between the at least one light pipe portion and the light emitting surface wherein the diffusion portion internally reflects the light towards the light emitting surface. The device may be a solid piece of plastic. The light pipe portions may be curved to bend light toward the illuminated surface.

Abstract: A latching device is provided for a circuit pack having a cable retainer carried upon the front of the operating lever of the device. The cable retainer is oriented for positional and directional control of cable by directing cable longitudinally of the faceplate of the circuit pack and away from the fronts of other circuit packs within a shelf.

Abstract: A latching device is provided for a circuit pack having a cable retainer carried upon the front of the operating lever of the device. The cable retainer is oriented for positional and directional control of cable by directing cable longitudinally of the faceplate of the circuit pack and away from the fronts of other circuit packs within a shelf. Also provided is a combination of a latching device and two groups of covers. The combination enables a single latching device to be used upon circuit packs requiring security and non security conditions within a shelf. It also enables removal of a faceplate held to a faceplate mounting with the circuit pack in the shelf. An orifice in an operating lever of the device is accessible with a cover of the first group mounted upon the operating lever, as orifices in these covers align themselves with the orifice in the operating lever.
