Reefkeeper DIY float switch.

[Ls7corvete]

See the link below, I simply put a microfit 3.0 connector on these, I figured someone without the crimping tool might want one. From what I read on Amazon, you can change NO/NC by flipping the float. Please see amazon for reviews, I cannot take responsibility for the reliability of the float.

I made three like this, be warned, the leads are 16"
