The switch shouldn't ever gum up - it should always be dry if all is running properly
Then you can put an ATO system in the sump

Excellent point!! Thanks for the advice, I may have to go that route.

Running a pump dry is never a good idea, even as a method of preventing a flood. While many modern pumps have thermal protection to trip power when they run dry or overheat, you're still risking a fire. Your hardwood floors won't get warped, but the house could burn down. So good call on some sort of float switch to cut power as a safety measure.
