If you ever come across an electronic component that looks like this (a small electrolytic capacitor or radial inductor) with simply the letters “HDX” and rattles if you shake it (even a little bit) then I’ll save you some trouble. It’s called a “vibration switch”! And, as you might guess, it’s a SPST switch that closes it’s contacts when it senses vibration. These are not as sensitive as a G-Force sensor but they can do the trick in telling something when it’s being picked up or moved around.

Well thank you sir!
I should have looked here first. Thanks!
Thanks for this info
