  • a gondola;

    a horizontal bus disposed along the length of the gondola, said bus having a plurality of wires;

    a plurality of vertical rails, each vertical rail of an insulating material, each vertical rail being of substantially constant cross section along its extent, each vertical rail having a front face and a back, each vertical rail having first and second edges along its extent and a ridge along each edge, each vertical rail having a channel in the front face and a plurality of exposed conductors within the channel corresponding in number with the wires of the horizontal bus, the first and second edges further comprising first keying means rendering the first and second edges nonsymmetrical with respect to reflection in the plane lying therebetween;

    connection means connecting the conductors of each vertical rail with corresponding wires of the horizontal bus; and

    a multiplicity of snap-on connectors with a plurality of the snap-on connectors mated to each vertical rail, each connector having first and second members engaged with the ridges of the first and second edges of its vertical rail, each connector further comprising springy contacts corresponding in number with the plurality of exposed conductors and disposed in tensioned mechanical contact therewith, each connector having a cable with wires corresponding in number with the springy contacts and electrically bonded therewith, each connector shaped between its first and second members so as to define second keying means mating with the first keying means.
