York S1-024-25006-701 SPST Pressure Switch 1.50"-WC

The York S1-024-25006-701 is a low-pressure switch suitable for use in heating, ventilation, and air conditioning systems. It is an essential element that controls the airflow management of the system. The pressure switch functions on the simplest principle; it turns on or off electrical circuits depending on fluctuations in static pressure. When the static pressure in the HVAC system falls to a predetermined low level 1.50” water column in this case, the pressure switch sends a signal, which under normal circumstances turns on or off a blower motor. This assists the system and avoids the destruction of the equipment. This pressure switch is mostly used in HVAC equipment including furnace-induced draft fans, air handlers, and blower systems.
