Tilt Sensor, Zero Power — SQ-SEN-815B

The SQ-SEN-815B series act like a position sensitive switch that is normally open when horizontal, and normally closed below the switch angle. They are designed to be non-sensitive to vibration in their horizontal positions. When at rest in a horizontal position, the sensor will settle in an open state. When tipped down from vertical to the "switch angle" it will produce continuous on/off contact closures while in motion. When at rest below the switch angle, it will settle normally open.
