Old thread now, maybe, and I have not followed it. But - depending on = the application, it could be possible to simply hinge a small "flag" in = an "optosensor". I refer to the "fork" arrangemant with a LED in one leg = and a photodiode in the other. Should be 2 USD or so. If a flag intrruptor is suspended to not possibly be caught by the fork, = you have a tilt switch, don't you ?
