ABSTRACT:
Apparatus for providing an electrical conduction path between a first contact location rotatable a plurality of rotations, in either direction, about a longitudinal axis, and a stationary contact location positioned radially from the rotatable contact location. Such apparatus is comprised of a bifilar spiral spring formed of a length of ribbon cable having at least two electrical conductors. The bifilar spiral coil spring is secured only by connections at its opposite ends to the two contact locations; whereby it uncoils and slidably moves in response to the direction of rotation of the rotatable contact location, and upon reversal of such rotation, recovers its original shape and position between the two contact locations.
