York S1-2940-3151 Pressure Switch 0.3" WC

The York S1-2940-3151 Pressure Switch is a high accuracy switch that is used in the measurement and control of pressure in HVAC systems. This type of pressure switch works with a range of 0.30” of WC and is ideal for use in applications where low pressure is needed to be detected. It has a normally open contact that closes when the pressure gets to the set level and the single pole design to guarantee durability. It is widely applied in furnaces, air handlers, and other equipment of HVAC systems in which pressure control is critical for operation safety and efficiency. It assists in avoiding system failure since pressure variations are corrected by sounding alarms or stopping parts that are potentially hazardous to the system.
