Lennox 11U70 Pressure Switch 322838-752 The contacts use yellow (common)The Lennox 11U70 Pressure Switch is a critical safety component engineered to monitor and regulate internal air pressure within high performance HVAC systems. This . 80 pressure switch (Catalog No. 11U70, Part No. 104371 07) is a single pole, single throw (SPST N. O.) contact rated for 5 Amp resistive at 24 VAC. Tasked with sensing the draft created by the inducer motor, it ensures the combustion process only initiates under safe airflow conditions.
