Images are for illustration purposes only. E&OE Overview SW-520D Roller Ball Tilt Switch, brass case sealed in Shrink Tubing to avoid short circuits. When the sensor is oriented so the leads are downwards, the mass rolls onto the poles and shorts them, acting as a throw switch. While not as precise or flexible as a a full accelerometer, roller ball tilt switches can detect motion or orientation simply. Accelerometers, on the other hand, output digital or analog voltage that must then be analyzed with extra circuitry. Characteristics: Specifications Contact Rating:12V Contact Resistance: <10 ohm Insulation Resistance:>10M ohm Capacitance:5PF Max voltage: 20V Max Current: 30mA ON at 30-90 degrees from horizontal position Pins have no polarity - can be interchanged
