Abstract: A rotatable electrical connector has a pair of wiring boards. Each wiring board supports two (or more) concentric conductors that have substantially smooth coplanar surfaces. The coplanar surfaces of the concentric conductors on each wiring board define a contact plane. To provide electrical contact between the two wiring boards, each wiring board is positioned perpendicular to an axis of rotation and is supported so that the respective contact planes of the first and second wiring boards are parallel. A resilient member, such as a spring, urges the wiring boards together to establish electrical contact between the respective surfaces of corresponding conductors on the two wiring boards.
