SW-520D is a commonly available roller-ball type tilt sensor which consists of two conductive elements (poles) and a conductive free mass (rolling ball), encapsulated in the same case.
The switch would be in the “off position” in the horizontal positon, “on positon” when raised to 10-90 degree or shakes.
These tilt switches use a metal ball which creates the same outcome as a mercury tilt switch, without the use of mercury and are ROHS compliant.
