Operator mechanism for control enclosure

An operator mechanism for a control enclosure, the operator mechanism comprising:

• a mechanical user interface configured to be physically moved by a user to actuate the operator mechanism;
• a shaft assembly coupled to the mechanical user interface such that movement of the mechanical user interface imparts movement to the shaft assembly, the shaft assembly having a length, wherein the shaft assembly includes:
• an elongate operator shaft having a longitudinal axis extending distally outward from the mechanical user interface, and
• a shaft extender coupled to the operator shaft and having an axis extending along the operator shaft, wherein the shaft extender is selectively movable along the operator shaft to selectively adjust the length of the shaft assembly;
• and
• a mount sleeve to facilitate mounting of the operator mechanism on a wall of the control enclosure, wherein the mount sleeve defines a longitudinal passage extending therethrough,
• wherein the shaft extender is received in the longitudinal passage of the mount sleeve and extends distally outward from the mount sleeve, the shaft extender being selectively movable longitudinally within the longitudinal passage of the mount sleeve relative to the shaft operator to selectively adjust the length of the shaft assembly.
