The International Comfort Products 1191249 is a Single Pole Single Throw (SPST) vent pressure switch designed for use in residential and light commercial HVAC systems. This safety switch monitors pressure differentials in furnace venting systems to ensure proper combustion air flow and safe operation.

Key Specifications:

This pressure switch is a critical safety component that opens or closes an electrical circuit based on the pressure differential in the vent system. When proper venting pressure is detected, the switch allows the furnace to operate. If inadequate pressure is sensed, the switch prevents ignition to protect against unsafe operating conditions. The 1/4 inch barb connection provides a secure attachment point for pressure sensing tubes.
