Tiny ball of mercury that moved inside a glass bubble. The glass has tiny contacts on the inside and the mercury would short circuit at least two at a time. It would detect sudden moves.
This is one type of tech that worked like that but maybe not exactlly like yours.
- function_seven 9y agoProbably similar to your description, but it was a solid ball that rattled. The enclosure was metal as well I think, though maybe some sort of laminated shell with alternating contacts? I'm really trying to find a diagram of it, but my searches aren't yielding much.
- K0balt 9y agoBall motion detectors (or shake/tilt switches) work as you describe. They typically have several metal rods on which the ball will rest on two at any given time. The impossible combinations (too far away to span with the ball) are often bridged together for simplicity. Detection is done by monitoring for changes in the connectivity between 3 or more contacts.
