White Rodgers 770-1 SPDT Air Pressure Switch 0.05-12.0 W.C.

The White Rodgers 770-1 is a versatile single pole double throw (SPDT) air pressure switch designed for HVAC and combustion control applications. This switch responds reliably to positive, negative, or differential air pressure changes within a range of 0.05 to 12.0 inches water column (W.C.).

Key Features:

• SPDT contact configuration for flexible control applications
• Wide pressure range: 0.05 to 12.0 inches W.C.
• Responds to positive, negative, or differential air pressure
• Reliable mechanical switching for safety and control circuits
• Suitable for furnaces, boilers, and ventilation systems
• Durable construction for long-lasting performance

This pressure switch is commonly used as a safety device to monitor air flow in combustion appliances, ensuring proper venting before allowing ignition. It can also be used in pressure sensing applications where SPDT contact switching is required based on air pressure changes.
