Presumably the moving contact moves away from the fixed contact at some point. Assuming that it is contact pressure, rather than oxidation, that is causing the fault, can you push the offending contact beyond its normal limit when the moving contact is out of the way? This might help increase the contact pressure sufficiently.
On the other hand, might the answer be to fix an arm on the switch shaft so that it presses on a small switch to by-pass the contact? Can you identify exactly which contact is the cause of the problem? Obviously stray capacity could make this option a no-no but it might be worth a try.
