Default What is this component? No markings whatsoever.

Hi All,

Could anybody please recognize this component? It has no markings and there is no designator on the board. It has no continuity, diode test shows also OL both ways.

The part has no leads, it looks like it fits in a socket? Designed to be replaced.
I would guess a gas discharge tube or higher power RF TX capacitor.

Ok that would make it a vibration or roller ball tilt switch. It must tell the MCU the tool is up or running.
Hold it up to your ear and shake it, see if you can hear the ball/roller/spring inside. Or put a DMM on continuity and tilt/shake the sensor see if you get a closed switch reading.
