Water Leak Detection

[John.N.]

I'm looking for a small switch that is sensitive to water, that can rest on a concrete floor raft, below foor boards which when in contact with a trace of water (water leak)will 'close' and allow me to connect to an alarm circuit.

Any help appreciated.

Don't know whether these US sources will help.

Check with local security/alarm dealers; they sell this sort of stuff.

Perhaps build a switch out of a spr> I'm looking for a small switch that is sensitive to water, that can rest on
