It's just struck me, that it might be worth re-visiting your opening gambit: i.e. Testing the reliability/repeatability of tilt switches by means of a test rig.
The discussion has moved to overcoming imagined issues with the current tilt switches - that may or may not, actually be occurring...
If your test rig ran at a speed more akin to the actual clock implementation, all that would be required, is to detect that a 'tilt' hadn't been detected within a certain time (at which point, stop the test).
Running very slowly, but continuously, would still put the tilt switch through its paces at a far greater rate than the actual clock implementation. If it passes that test, then issues in the field must surely be to do with the implementation or environment.
(Between us, we can easily get that test rig working )
