I have successfully taken the switch itself apart and cleaned the internal working mechanism and the contacts as well. You have to pry off the plate that covers the top of the switch assembly, and then all the parts can be removed.

I think you can clean them better this way, using a Scotchbrite pad or similar, than with a shot of contact cleaner into the top. You also can remove all the lint and dust that has fallen down in there over the years. Besides, it's cool to see what a real German made switch looks like inside. I'd never disassembled a switch before, and these are heavy duty.

Just be careful to do the surgery on a well-lit kitchen table type area, because there are several small parts, including a couple springs, that will want to jump out as soon as you get the top plate off the thing. I cleaned the switch on my 1977 300D, and the fix worked until I sold the thing. If you clean yours properly, that switch should be good for another 16 years My 84 switch is getting intermittent, so maybe they only last 16 years before needing a cleaning.
