Technologies pertaining to a rotary electrical contact device are described herein. A rotary electrical contact device comprises a first sheave that is disposed about a first axis and a second sheave that rotates about the first axis or a second axis that is parallel to the first axis. The device further includes two planetary sheaves that revolve around the first and second sheaves, and a belt that makes contact with each of the sheaves, the belt comprising a co-wound inner helical coil and outer helical coil. As the first sheave rotates, the planetary sheaves revolve about the first and second sheaves and cause the belt to deform and roll along the second sheave. The belt makes rolling contact with the four sheaves. The belt is electrically conductive such that as the belt rolls along the sheaves, the belt maintains electrical contact between the first sheave and the second sheave.
