Abstract
A spring ring circuit assembly is provided for transmitting electricity between a first structure and a second structure which rotates relative to the first structure. The spring ring circuit assembly includes a spring ring which is affixed to and concentrically positioned around a spindle. The spring ring circuit assembly further includes a circular band concentrically positioned around the spring ring so as to create an annular space between the spring ring and circular band. The spring ring circuit assembly further includes an inner set of rollers positioned around and engaging the spring ring, and an outer set of rollers positioned within and engaging the circular band. The spring ring, rollers and circular band are made of electrically conductive materials so as to allow electricity to transmit between the spring ring and the circular band which is capable of rotating around the spring ring.
