So there's no electrical switch in there? It's just a sealed plastic housing with a steel rod attached to the "switch"? Well, if the steel rod is rusted, submerge the whole thing in acid. Acid is usually harmless to plastic, and will dissolve the rust making the rod stick. Not for too long, mind you. Only long enough to free the rod and see some rust come out in the acid bath. Afterwards, rinse throughly, dry, then soak the whole thing in WD40. (The "WD" stands for "Water Displacement.") Allow that to dry, then lube the rod with white lithium grease.
Maybe test some muriatic acid on an inconspicuous part of the plastic. Hopefully there's nothing else in there. Granted, it's a radical idea, but what's the alternative? Attempting to lubricate it will work for a while, until the tight-fitting rust simply pushes all the lubricant away. | ||
