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