1. A surgical instrument, comprising:

  • a rotary motion generator;

    a shifting assembly, comprising;

    a first output selectively drivable by said rotary motion generator, wherein said first output is configured to transmit a first rotary motion;

    a second output selectively drivable by said rotary motion generator, wherein said second output is configured to transmit a second rotary motion;

    a switch configured to switch between the selective drivability of said first output and the selective drivability of said second output, wherein said second output is operably demeshed with said rotary motion generator when said first output is driven by said rotary motion generator, and wherein said first output is operably demeshed with said rotary motion generator when said second output is driven by said rotary motion generator; and

    a biasing mechanism configured to motivate and maintain an operative meshment between said rotary motion generator and one of said first output and said second output;

    a rotatable shaft, wherein said first output is configured to transmit the first rotary motion to said rotatable shaft;

    an end effector comprising a first jaw and a second jaw, wherein said first jaw is moveable relative to said second jaw during a closing motion; and

    a firing member moveable relative to said end effector during a firing motion, wherein the closing motion is separate and distinct from the firing motion.
