Has anyone used these as replacements for key contacts, and what was your experience with them?

I've used Roman's modules and liked them a lot, but I am wondering how much of a problem interplay with neighboring magnets would be? Since I am already going to be using magnets for simulated tracker touch on my next project, it would be nice if I could use the same magnets to trigger the Hall-effect sensors (however I have no experience working with anything but mechanical switches). Any tips on what could go wrong with this scenario?
