Description
The Supco SHF140 is a precision-engineered snap disc fan switch designed for reliable temperature-activated fan control in HVAC and appliance applications. Featuring a fixed 140°F cut-in temperature and a fixed 120°F cut-out temperature, this switch uses a close-on-rise switching action to automatically energize the fan circuit when the set temperature is reached and de-energize it as temperatures fall — ensuring efficient, consistent airflow management.
Built with an auto-reset mechanism, the SHF140 eliminates the need for manual intervention after a temperature event, making it ideal for installations where continuous, unattended operation is required. The snap disc design provides fast, positive switching action with minimal contact bounce, delivering long service life and dependable performance cycle after cycle.
