Abstract: Multiple resistance elements are mounted in parallel pairs around the inside curved wall of the assembly housing. Multiple cylindrical contacts in a planetary arrangement are rotated by a friction drive surface mounted on the control shaft. Each cylindrical contact rolls on one pair of resistance elements. The cylindrical contacts, by being movable shunts between the parallel strips, provide ganged multiple potentiometer or rheostat capability. No terminal is connected to any moving part. The diameter of the drive surface and the diameter of the cylindrical contacts determine the possible number of resistance elements per assembly. Shaft rotation for full range variation, thus vernier capability, is determined by the ratio of the drive surface diameter to the inside diameter of the housing.
