Hi Dale,

: I think I bought the same thing a while back, but haven't gotten far enough
: to hook it up yet.

: I think they are just made to be water resistant. I think you might have to
: put it on with sealant on the threads to make it waterproof. Another way
: might be to use the white teflon tape that plumbers use on the threads.

The ones I bought have a gasket under the threads to seal to the switch mounting surface. This should eliminate thread leakage but when I build it permanent I will use a semi permanent thread locking compound which will seal them furthe and stop the switch from coming loose.

: The water won't be under too much pressure to get in (unless you sink your
: kayak ) so it probably isn't that critical.

: I'll be interested to see how your test works out.

Yes, I will too. This seems too easy but I have all the pieces and can't see a problem anywhere. The proof is in the pudding as they say so I will know for sure tomorrow when I get the pudding, oops! I mean switch, together.

I'll let you know,

Ian
