The airflow switch senses static differential pressure and the diaphragm operated snap switches actuate electrical circuits. This 141-0518 provides automatic reset. Auto reset switches should be used for applications requiring positive proof of airflow (or Fan operation) or to detect high differential pressures associated with dirty air filters or similar maintenance alarms not requiring safety lock-out (shut down) of the Fan.
