Abstract

A low voltage power assembly may comprise a track that includes one or more conductive plates and one or more metal plates, wherein the track is powered from a low voltage power source; and a power connector assembly that connects to the track, wherein the one or more conductive plates connect to the power assembly providing a low voltage power connection, and further wherein the one or more metal plates connect to the power assembly providing a magnetic connection. The power connector assembly may be configured to provide low voltage power through the track to a low voltage power device. The low voltage power assembly may include a configuration of ferrous material, conductive material, and nonconductive materials arranged in such a way as to provide a method for power and/or signal distribution to a mating device, such as to a set of magnetic LED modules.
