Can't post pics cause problems on your end. Probably my phone takes too large images.
They are little metal cubical boxes with a black ball inside. the ball is not loose but held behind a metal cage. there are 3 pins eminating from them. the number 3 is stamped on the front. No other markings. Box is well under a centimeter. I took these off of somethiing about 10 years ago, cause they looked neat.
