Abstract: A light panel for the electrical mounting of components of airborne equipment is disclosed and comprises a first rigid plate having a plurality of holes for allowing component operating knobs to pass therethrough, a plurality of rings for individually guiding the knobs as well as holding components associated with the knobs in a fixed position, a printed circuit board having holes corresponding to like holes in the rigid plate and including conducting tracks for supplying electric power to microlamps which illuminate the knobs, and an insulating support plate for supporting component housings and electrically connecting the components to electrical conductors.

Abstract: In a system including an electrical power center for producing and distributing electrical energy for vehicles, particularly aircraft, primary circuit breakers and contactors are distributed between a D.C. electrical power center, relay boxes, electronic bays and control panels and the electrical power center forms a central unit grouping together different protection or safety devices. The system permits the electrical network on board an aircraft to be simplified and lightened.
