Description
The York S1-024-39706-000 Pressure Switch monitors pressure changes and produces an electrical response when airflow drops to the specified threshold during operation. Featuring a 0.10 on-fall pressure setting with a single-pole normally open SPNO configuration, this switch reacts to draft or pressure variation by completing circuit action only under required conditions. Found near inducer assemblies, combustion sections, furnaces, and HVAC systems, integration allows airflow verification before heating sequences continue. An accurate pressure response improves equipment safety and reduces operating interruptions linked to insufficient airflow.
