Mercury Tilt Switch - 3mm or 5mm - 100 Pack

Easily detect tilt or motion using these mercury tilt switches from PMD Way. 

They operate as a normally-open SPST switch - but when the device is tilted up and the ball of mercury falls to the bottom, the switch is closed. 

Maximum 12V DC 1A.

Please note that mercury is dangerous if exposed to the atmosphere, so don't break the glass.
