Source1 2435776000 Air Pressure Switch 0.40 Inches Wc on Fall Spno

Product Description

The SOURCE1 2435776000 is an OEM air pressure switch designed to monitor and respond to changes in air pressure within HVAC systems. It activates on a pressure fall of 0.40 inches WC and features a Single Pole Normally Open (SPNO) configuration. This switch plays a critical role in protecting heating and cooling equipment from operating under unsafe or inefficient pressure conditions. When the system pressure drops to the set point, the switch closes the circuit and signals the unit to respond accordingly. This built-in safety mechanism helps prevent equipment damage, improves system reliability, and supports consistent performance across a wide range of operating conditions. HVAC technicians rely on pressure switches like the 2435776000 to maintain proper draft pressure in gas furnaces, air handlers, and other forced-air systems. A faulty or failed pressure switch is one of the most common causes of furnace lockout or no-heat calls, making a reliable OEM replacement essential for fast, accurate service. This SOURCE1 part is engineered to match original manufacturer specifications, ensuring a direct fit and proper calibration right out of the box. It is compatible with a range of popular York and related equipment models, including units in the 1NP0807 and 2EE04701024 series. The switch measures 5.85 inches in length, 3.5 inches in width, and 3.2 inches in height, with a shipping weight of 0.7 pounds. Its compact form factor fits standard HVAC cabinet configurations without modification. Whether you are replacing a failed switch or stocking up for the heating season, the SOURCE1 2435776000 delivers the OEM quality and exact specifications HVAC professionals need to complete the job right the first time.
