If I had a switch like that one and I felt it was gummed up, I think I'd try spraying it with a penetrant like WD-40 and letting it sit for just a few minutes, maybe five, and then I'd try the throwbars. It may only need to have organic crud thinned. After it seemed to be freed, I would then rinse it thoroughly in warm water and soap. In fact, you might consider trying TSP in fairly hot water, and swish it around every 15 or thirty seconds, trying the throwbars every minute or so. Sudsy ammonia might do the trick, too.
