  • Automatic reset restores operation without manual intervention
  • Closes at 150°F to activate fan when temperature rises

HVAC Fan Switch — Closes at 150 °F

This temperature limit controller manages fan operation in heating and cooling systems. It uses a single-pole single-throw contact that closes on temperature rise and resets automatically. The unit is rated for 120 V AC and 277 V AC supplies.

Voltage and Mounting Check

Verify that your control circuit operates at 120 V AC or 277 V AC before wiring. Confirm a surface-mount location with space for a 2 in by 1 5/8 in base. Ensure the application requires a switch that closes at 150 °F and opens at 130 °F.

Build and Daily Use

The housing is made from recycled plastic in a red finish. Automatic reset means the fan restarts without manual intervention once temperature falls. The 20 °F differential prevents rapid cycling during normal operation.

Questions about this item

Does the package include mounting hardware or do I need to buy screws separately?

The switch has a surface-mount base measuring 2 in by 1 5/8 in; mounting screws are not included and must be sourced separately

Is there a model with a different closing temperature than 150 degrees F?

This controller closes on rise at 150 degrees F and opens at 130 degrees F with a 20 degree differential; no alternative temperature versions are offered in this listing

What does the 150-degree closing point mean when the switch is installed in an HVAC unit?

When the sensed temperature rises to 150 degrees F the SPST contacts close automatically to energise the fan circuit, then reopen once the temperature falls back to 130 degrees F
