Abstract
An operating mechanism that provides multiple operational output states at a first output and additional operational output states at a second output that are synchronized with the first output to provide a predetermined sequence of control. The operating mechanism includes an output lever that is pivoted by the stored energy in a spring and latch levers that are selectively operated to release the output lever. When the output lever is moved between operational positions, the output lever is stopped in its pivoting movement via the latch levers.
