The F262 series airflow switches detect airflow or the absence of airflow by responding only to the velocity of air movement within a duct . The single-pole , doublethrow ( SPDT ) switch can be wired to open one circuit and close a second circuit for either signaling or interlock purposes .
Airflow failure during the normal operation of air handling systems may cause overheating , coil icing , or other conditions that may be detrimental to the equipment .
