Re: What is this component?

It came out of a GPS / Bluetooth reciever, I think it's a motion/
vibration sensor of some sort, to save battery, ie when it hasn't
moved for a certain amount of time the unit will shut off. It probably
generates a closed circuit when the ball(or whatever) inside moves and
touches off 2 different terminals.

You say "probably". If the device just consists of four terminals and
a rolling ball, then surely it wouldn't be too hard to confirm this
with a multimeter?

Can't seem to find any examples of them on the web though.

I searched for "rolling ball" and "motion sensor" and found this:

I find the references to "test circus" and "rang of pin" a bit of a
worry, though. :-)
