Abstract
A controlled bi-directional electric motor is energized for armature rotation in respective opposite directions in response to the operation of an electrical control switching arrangement electrically open and electrically closed. A mechanically operable electrical switching device arranged to be operated by a mechanical movable member that is driven between first and second travel limits by the controlled motor is effective, when the movable member is driven by the motor to either travel limit, to interrupt motor energization and to condition the circuit for effecting motor energization for armature rotation in the direction to drive the movable member toward the other travel limit.
