SOURCE1 2435262000 Air Pressure Switch 1.20 on Fall Single Pole Normally Open

Product Description

The SOURCE1 2435262000 is an air pressure switch designed for use in residential and light commercial furnace systems. It monitors pressure changes inside the HVAC unit and triggers on/off control to manage safe and efficient operation. When the pressure drops to the activation threshold of 1.20 inches on fall, the switch responds to signal the system to proceed or shut down based on operating conditions. This type of pressure switch is a critical safety component in forced-air furnaces. It verifies that the inducer motor is creating proper draft before allowing the ignition sequence to begin. Without a functioning pressure switch, the furnace control board will not initiate the heating cycle, which helps prevent dangerous conditions such as incomplete combustion or flue gas backdraft. The SOURCE1 2435262000 uses a single pole normally open configuration. In the normal resting state, the circuit is open. When the correct negative pressure is sensed, the diaphragm inside the switch flexes and closes the circuit. This confirms to the furnace control board that safe draft conditions exist. HVAC technicians rely on this type of OEM-grade replacement switch when diagnosing furnace no-heat calls, pressure switch fault codes, or inducer-related lockouts. This part fits several popular York and compatible units including 2TP04523625, 2HN04601625, and 6MG10 models. Its compact dimensions of 4.5 inches in length, 4 inches in width, and 4 inches in height make it easy to install in tight furnace cavities. At just 0.202 pounds, it is lightweight and straightforward to handle during service calls. Using a genuine OEM-quality replacement ensures proper calibration and reliable long-term performance.
