York S1-024-36052-014 SPNO Fall Pressure Switch Close On 1.7" WC

The York S1-024-36052-014 Fall Pressure Switch is a safety part used to protect systems from the hazards associated with low pressure. It is an SPNO switch, which is open when it is not pressed and closes when the pressure drops below 1.7 inches of the water column. A diaphragm within the switch reacts to pressure variations. When the pressure is below the setpoint, the diaphragm if moves and closes the switch that sends a shutdown signal. This avoids damage to equipment resulting from low pressure situations in applications like HVAC systems, Plumbing & Industrial Processes.
