1. An electromechanical surgical system comprising:

  • a handle assembly;

    a drive motor supported in the handle assembly and extending to a drive gear;

    a selector cam defining a recess;

    a selector motor extending to a selector gear, the selector gear positioned to move the selector cam between a first position and a second position;

    a first output assembly including a first output shaft and a first output gear, the first output shaft selectively coupled to the first output gear by a first engagement key, the first output gear rotatable with the drive gear of the drive motor, the first engagement key positionable within the recess of the selector cam while the selector cam is in the first position to engage the first output gear with the first output shaft, the first output shaft rotatable with the first output gear in response to rotation of the drive gear of the drive motor while the first output gear is coupled to the first output shaft, the first output gear being rotatable relative to the first output shaft while the selector cam is in the second position; and

    a second output assembly including a second output shaft and a second output gear, the second output shaft selectively coupled to the second output gear by a second engagement key, the second output gear engaged with the first output gear of the first output assembly, the second engagement key positionable within the recess of the selector cam while the selector cam is in the second position to engage the second output gear with the second output shaft, the second output shaft rotatable with the second output gear in response to rotation of the drive gear of the drive motor while the second output gear is coupled to the second output shaft, the second output gear being rotatable relative to the second output shaft while the selector cam is in the first position.
