My testing has shown them repeatable within half a thou or better.
I also tried some magnetic reed switches and the small (approx 1/8" dia)
rare earth magnets Radio Shack sells, and found them repeatable to
.0002! However I got enough feedback regarding bounce and other issues I
decided not to pursue any further.
