"Unbeatable"
I use it as a bilge pump switch in our boat. It is connected to a homemade PVC air bell acting as a trash filter and the switch is mounted in a convenient place out side of the bilge. It won't corrode and is easily fine tuned to pump prime height requirments. No wires in the bilge and you can check switch operation on your feet instead of your knees.
