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. The
single-pole, double-throw (SPDT) control 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.
Refer to the F262 Airflow Switch Product
Bulletin (LIT-12011988) for important product
application information.
Application
