Can anyone point me in the direction of a float switch that could be used to kill power to a underground pool vault that contains the pool pump and other pool associated electrical.Appears some kind of switch was originally installed from the manufacturer but was removed for whatever reason over the years.Looks like there was a bracket that sat about 2" off the bottom of the vault.Owner has no literature on the unit, appears to be foreign(possibly Italian). Thanks much.

Not knowing any of the details as to how it was set up originally could be fun but google "float switch" use your imagination take your pick. All sorts of different ways to do this. How does the room get it's power? via a contactor, a shunt trip breaker? The whole room or just shut down the pumps?

why would you want to shut it down anyway?
it may have been removed because it was deemed undesirable.

Maybe think of it as a back flow preventer. IE, Call for circulation, the stop and actively stop head pressure on system line and propellers, but maintain water in system.
A flow arrow is usually on cast
LOL, or its a sump pump...
You cou probably find a image using "diagram ..." in google to see the placement.

When you had pumping equipment in a "dry pit" that does not drain, it becomes a sump if anything leaks. So if there was no sump pump to keep it dry, they would have installed a float switch controlling a shunt or UV trip on a breaker feeding power to that equipment pit in the even of a build-up of water in it. Any kind of float switch would work if that's the case, but the level at which it activates would be critical. No point in even having it if the water builds up to where it can make electrical contact with anything anyway.
However, that was something that was used back when nobody had heard of a GFCI. I haven't seen one in 30 years. That may be why it was removed, a GFCI would accomplish the same net effect, protecting people from "hot" water.
