Bradford White 415-45867-02 Pressure Switch 1.25" WC N/O

The Bradford White 415-45867-02 is a normally open (N/O) pressure switch designed for use in Bradford White water heaters and hydronic heating systems. This safety component monitors air pressure in the combustion chamber and venting system, ensuring proper draft conditions before allowing the burner to operate.

Key Specifications:

• Pressure rating: 1.25 inches water column (WC)
• Switch configuration: Normally open (N/O)
• Direct OEM replacement part for Bradford White equipment
• Ensures safe operation by verifying proper draft and venting
• Prevents burner ignition without adequate combustion air pressure

This pressure switch is a critical safety component that helps prevent dangerous combustion conditions. When proper air pressure is achieved in the venting system, the switch closes to complete the electrical circuit and allow the ignition sequence to proceed. If inadequate draft or blocked venting is detected, the switch remains open, preventing burner operation.
