ABSTRACT:
An apparatus is provided for electrically indexing a rotary component. It includes a housing, a resilient, electrically conductive band contained within the housing and connected to the rotary component, at least two indexing electrical contacts located on the housing internal periphery and in slidable contact with the band, and a bridging electrical contact in connection with the band. The band exerts a biasing force on the housing, thereby maintaining band contact with the housing internal periphery, while also causing a point of separation of the band from the housing. Electrical circuitry is also provided so that once an indexing contact has been selected, the band and the rotary component can be rotated until the band disengages from the selected indexing contact, thus halting further movement of the band and the rotary component.
