ABSTRACT:
Track lighting apparatus is disclosed which includes a track section, plug box and plug connector designed to incorporate two lighting circuits independently controllable within the same track section. The track section includes a neutral bus and a grounding bus on one lateral side and two independent voltage busses on its other lateral side. The head of the plug box inserted in a bottom slot running the longitudinal length of the track section, may be rotated into position in only one direction, thereby preventing inadvertent connection of neutral and grounding contacts to voltage busses and vice versa. The plug box head has a voltage contact which may be mechanically moved between two positions for alternative connection to either of the voltage busses of the track when the plug head is connected to the track. The plug connectors, one designed for insertion via the right hand end of the track section, the other via the left hand end, are provided to connect two or more track sections together in straight, "L", "T" , or "X" patterns, or to provide electrical feed from the wall or ceiling on which the track is installed or to provide track section termination. The plug connectors include a grounding finger to connect the track structure to the grounding bus and includes an inverse L shaped channel in which a connection member is disposed. The connection member includes a lateral contact, a vertical member and a lateral terminal member.
