• 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 15-90 degree or shakes.
  When the OFF end of the switch is lower than the horizontal angle by 15 degrees, it is difficult to trigger conduction when shaking.
  This switch is suitable for triggering small current circuits and is not suitable for power switches.
