ABSTRACT:
A three-position electrical driving mechanism having a jump-drive sub-assembly, a pivotable actuator and associated spring arrangement for storing energy, a detent arrangement and associated latches for holding the detents in place, a release arrangement for disengaging the detents from the latches, and a storage drive sub-assembly which is operable in response to a blown fuse or an open circuit trip. This switch requires the operator to perform the same switching operation each time the switch is utilized, and therefore errors that occur when an operator must perform several different operations are avoided.
