THEORY OF OPERATION
The SQ-MIN-200 series sensor acts like a normally closed switch which chatters open and closed as it is tilted or vibrated.
Note that the SQ-MIN-200 is not guaranteed to be closed—even when the sensing mechanism is at rest. However, a good
rule of thumb is that 75% - 95% of the time (depending on orientation) when the sensor is at rest it will be closed. The
engineer should design his or her software to look for high-to-low and low-to-high edge transitions rather than an open of
closed state of the switch.
