And just to confirm - this switch should only control the water heater, but nothing else like the refrigerator?
Correct. It's only for the 120V heating element on the water heater. I've never actually turned ours on in the 13 years we've had our camper. We're usually not on hookups and if we were I wouldn't want to use 12A before running anything else.
You also want to never have it on when the water is drained or the element will go poof. Some of those switches have a hole for a cotter pin to lock it "off" when drained.
