what you need:
1. a micro switch with level arm. like this one
2. some 316 grade stainless sheet 1mm thick or thread bar etc.
3. something that floates like ping pong balls or somthing. i like using the modern toilet cistern floats, the really tiny ones.and thats all.
then do this
the red is the added stainless steel strips or bar. i just cut stainless sheet into thin strips and bent it like that
iv used these in many projects of mine and the work great. the micro switches have a normally open and normally closed and can control 250v 4A. i personally wouldnt put 220v near my tank like that. let it rather switch 12v to control a relay to switch 220v.need any help on that, just ask
i used them on my scrubbers sump before a went electronic. i relied on these things to make sure my lounge stayed dry they worked great!
