Hopefully this is a pic of my idea for a float switch. This is just a basic concept. The box and lever is a small switch from radio shack. I wish I could remember the name for it, but it just has a lever on it. Anyway, if you attach an arm (probably bent) to it and put a styrofoam ball on the end it could be used in a bong reservoir to protect your pump and computer. All you would have to do is use a normally open switch and mount it the way it is in the pic. The raising water would close the switch and let your pump start pumping. You could use a second one with an LED (normally closed) for a warning that a shutdown is about to occur.
Just a thought.
