Tilt Switch Ball Sensor (SW-520D)

SW-520D Ball Tilt & Angle Sensor Breakout

The SW-520D tilt sensor contains two gold-plated conductive balls inside a sealed cylinder. When tilted past 15-45 degrees, the balls roll away from the contact pins, changing the electrical circuit state. Ideal for rollover warnings, toy orientation, and power-saving sleep triggers.
