Those particular type of switches are pretty common in SW Florida. Anyone with a well has at least one. They are tywrapped to the pipe in the aierator tank so they open the circuit to the valve or pump when the tank is full. They come in NEMA 5-15 and 6-15. We don't need any more government "help" on the design. ;-)

They cord and plug connect. That is the disconnect
