An apparatus comprises a first plate having a first plurality of conductive segments on a surface of the first plate and a second plate having a second plurality of conductive segments on a surface of the second plate. The first and second plates have an axis of rotation. The first plurality of conductive segments and the second plurality of conductive segments each have a circular shape with centers through the axis of rotation. Each of the first plurality of conductive segments and the second plurality of conductive segments has a different diameter. Portions of the first plurality of conductive segments and the second plurality of conductive segments are offset from each other along the axis of rotation. Corresponding segments in the first plurality of conductive segments and the second plurality of conductive segments conduct signals during rotation of the first plate and the second plate relative to each other.
