International Comfort Products WC SPST Pressure Switch

The International Comfort Products WC SPST pressure switch line offers OEM replacement vent pressure switches (also called air pressure switches or draft inducer pressure switches) for residential heating and HVAC equipment. Each switch is a single-pole, single-throw (SPST) device that reacts to pressure measured in inches of water column (WC).

Key Features:

• SPST switch design that opens or closes the control circuit when pressure reaches its set point
• Calibrated to a specific water column (WC) pressure rating, with several ratings available in the line
• Helps confirm proper venting and airflow before the system operates
• Turns the system on or off when pressure is outside the set range, which helps prevent unsafe operating conditions
• Genuine OEM replacement part from International Comfort Products, a Carrier Global subsidiary

Pressure switches like these are commonly used in furnaces and other heating equipment to protect the system and support efficient, reliable operation. Choose the variant whose pressure rating matches your original part.
