International Comfort Products 1193107 WC SPST Pressure Switch - 0.35

The International Comfort Products 1193107 is a Single Pole Single Throw (SPST) pressure switch designed for HVAC furnace applications. This safety component monitors air pressure in the furnace draft inducer system to ensure proper venting before allowing the burner to ignite.

Key Features:

• Pressure activation set point: 0.35 inches water column (WC)
• SPST (Single Pole Single Throw) switching configuration
• Ensures safe furnace operation by verifying proper draft inducer pressure
• Direct replacement OEM part for International Comfort Products furnaces
• Safety interlock prevents furnace ignition without proper venting

This pressure switch is a critical safety component that prevents furnace operation when adequate combustion air pressure is not present. When the draft inducer motor creates sufficient negative pressure (0.35" WC), the switch closes to complete the control circuit and allow the ignition sequence to proceed. Compatible with various ICP brand furnaces including Heil, Tempstar, Arcoaire, and Comfortmaker models.
