The slip ring defines a circumference and an electrical contact groove extending around the circumference of the slip ring. The electrical contact assembly preferably includes a plurality of electrical contacts spaced around the circumference of the slip ring for engaging the electrical contact groove. In addition, an urging mechanism is preferably associated with each of the electrical contacts for urging the electrical contacts toward engagement with the electrical contact groove. Finally, a wiper is preferably associated with each of the electrical contacts for extending within the electrical contact groove to inhibit a fluid from passing through the electrical contact groove.
