Description

Built with a Single-Pole Single-Throw (SPST) switch action, this pressure switch monitors and confirms proper draft or airflow conditions before allowing burner ignition — a critical safety function in modern heating equipment.
Key Features
- SPST (Single-Pole Single-Throw) switch action for reliable open/close circuit control
- Factory-calibrated pressure setting of 0.30″ W.C. (inches water column)
- Rated for use from sea level up to 4,000 ft. elevation
- Genuine Weil McLain OEM replacement part — SKU 511-624-532
- Designed to verify adequate combustion air and venting before burner operation

Application
This differential pressure switch is a key safety component in Weil McLain boiler systems. It senses the pressure differential created by the inducer blower during operation. If the required pressure differential is not achieved — indicating a potential venting or airflow problem — the switch remains open, preventing ignition and protecting the system and occupants from hazardous conditions.
