F262 Airflow Switch Description The F262 Airflow Switch detects airflow or the absence of airflow by responding only to the velocity of air movement within a duct. You can wire the single-pole, double-throw (SPDT) control 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. Refer to the F262 Airflow Switch Product Bulletin (LIT-12011988) for important product application information. Application Typical applications include: • Make-up air systems • Air cooling or heating processes • Exhaust systems The control includes a Type 3R (NEMA) enclosure with an integral mounting plate.
