Safety Float Switches - Help Finding Please

[Brent Thomann]

anyone know of any inexpensive float switches?

looking to install on the top of my tanks some how so if the water gets to high (from drain being plugged) it shuts off a return pump.

need one that isn't too bulky as my one tank has no top, just hanging pendants.

I'm pretty sure that's the one I use. You just turn the float upside-down to switch from normally closed to normally open or vice-versa.

Oh, and personally, I wouldn't run any serious amperage through any float switch. Use DC (12V, 5V, etc...) and isolate the pump with a relay.

That switch won't take more than 0.25 amps, anyway.

ShapeGSX, thank you very much. I am not very familiar with relays and such, I'm sure its easy, just never messed with them before.

looking for something a little more easier I guess.

Possible, just a little bulky will have to have it above and out of the water so when the water raises, it then turns pump off.

any others guys?
