5. An indication system comprising:
an enclosure;
a lever arranged to magnetically couple with
a mechanism within the enclosure;
an indicator mounted to an outer surface of the enclosure; and
a magnet coupling the indicator to a component of the mechanism indicative of a state of the mechanism, the magnet forming a magnetic coupling extending between the indicator and the component across a shell of the enclosure such that the shell of the enclosure is between the lever and the mechanism to seal the mechanism from an outside environment and the lever, the indicator displaying a reading indicative of the state of the mechanism responsive to the magnetic coupling.
