By failing in the "On" position do you mean that the shaft is seized or that it is free but the magnetic tuning will not turn off? If it is seized I would squirt some penetrating oil on the shaft bushing letting it soak for a while, and maybe apply a little heat too like from a soldering iron, and see if that frees it up.
If it is really bad I would think about removing the switch and taking it apart to clean the hardened grease or rust out of it. Usually these have a "C" clip on the shaft just in front of the bushing which holds the shaft in place, if you remove that then you can get the shaft assembly out through the rear, that is if it's a normal rotary switch.
