Adapter for dual circuit track lighting system

Abstract

A track adapter (10) is disclosed for electrically connecting a light fixture to either of two electrical circuits (42, 43) of a track (22). The track adapter (10) includes a housing (14) and a housing base (12) having a slot (72) formed therein. An electrical contact (20, 220) has an elongated leg (120, 240) which is received through the slot (72) such that a first end (154) of the contact (20, 220) terminates within the housing (14). The electrical contact (20, 220) is movable within the slot (72) between a lower position in which the electrical contact (20, 220) contacts the voltage bus (42) of a first electrical circuit within the track (22) when the adapter (10) is mounted to the track, and an upper position in which the electrical contact (20, 220) contacts the voltage bus (43) of a second electrical circuit within the track. The electrical contact (20, 220) has a lateral protrusion (150, 250) which creates an interference fit with the slot (72) so as to inhibit the electrical contact (20, 220) from moving between the upper and lower positions. The protrusion (150, 250) is disposed above an upper end of the slot (72) when the electrical contact is in its upper position, and the protrusion (150, 250) is disposed below a lower end of the slot (72) when the electrical contact (20, 220) is in its lower position.
