Same idea as the one on your console, but instread of a finger toggle it has a float - when the float rises, the switch is switched.
"Electronic" ones have a couple of metal studs that are at a couple of volts dfference. When "shorted" by water the circuits inside use the small current between the studs to recognise the water is there & electronically switch the big current. Problem with these types in a rib is its usually wet on a good day!
