Source1 2435286000 Air Pressure Switch -0.90 on Fall Spno

Product Description

The SOURCE1 2435286000 is an air pressure switch designed for use in HVAC systems where reliable pressure sensing and circuit control are required. This switch is configured as a Single Pole Normally Open (SPNO) contact type, meaning the electrical circuit remains open under normal conditions and closes when the monitored air pressure reaches the set trip point. The set point for this switch is -0.90 inches of water column, activating on a pressure fall. This means the switch closes its contacts when the sensed negative pressure drops to or below -0.90 inches water column, signaling the control system to respond accordingly.

Air pressure switches like the SOURCE1 2435286000 are critical safety and operational components in gas furnaces, air handlers, and other forced-air HVAC equipment. They are commonly used to verify that the inducer motor or draft blower is operating correctly before allowing ignition to proceed. If the inducer fails to generate the required negative pressure, the switch remains open, preventing the furnace from firing and protecting against unsafe operation. HVAC technicians, service professionals, and equipment installers rely on pressure switches during routine maintenance, system diagnostics, and component replacement to keep heating systems running safely and efficiently.

This replacement air pressure switch is compatible with systems that require a -0.90 inches water column fall-activated SPNO switch, making it a go-to part for furnace pressure switch replacement jobs. The SOURCE1 brand is a recognized supplier of OEM-quality HVAC parts trusted by trade professionals across residential and light commercial applications.

• SPNO (Single Pole Normally Open) contact configuration for standard HVAC control circuit integration
• Set point of -0.90 inches water column, activating on pressure fall for accurate draft sensing
