Patent ID: 7416422

Claim:
A method comprising: providing a lighting track comprising a first pair of buss bars; positioning a portion of the lighting track in a flexed configuration coupling a transformer assembly comprising a housing, a rotatable cover, at least one contact, and a transformer to the lighting track, comprising: electrically coupling the transformer to the first pair of buss bars of the lighting track by coupling the contact to at least one of the buss bars toollessly coupling the transformer assembly to the lighting track comprising: positioning a portion of the lighting track adjacent to the housing and the cover, wherein the cover comprises a fixed and a free end; rotating the cover relative to the housing until the free end engages a portion of the housing, thereby positioning the portion of the lighting track between the housing and the cover; rotating the contact relative to the housing to accommodate the portion of the lighting track in the flexed configuration; and generating a biasing force on the contact in the direction of the buss bar to maintain the electrical coupling between the contact and the buss bar when the lighting track is in the flexed configuration.
