ABSTRACT:
A lamp and support housing are adapted for movement along the length of a power supply track. The housing supports movable contacts each adapted to be electrically coupled to a discrete conductor bus in the track. An actuator on the housing moves the contacts between an inoperative retracted position and an operative extented position. Access to the conductor buses is attained by way of slots on opposite faces of the track.
