Rheem-Ruud 42-101955-08 Pressure Switch Assembly SPST Water Column 25"

The Rheem-Ruud 42-101955-08 Pressure Switch Assembly is a part intended to monitor and control the operations of HVAC systems to guarantee their safe function. This type of pressure switch has SPST configuration and it has a pressure rating of up to 25-inch water column. This pressure switch monitors the amount of air pressure inside the HVAC system, and according to the chosen pressure parameters, it manipulates electrical circuits. The switch activates or deactivates system parts such as the burner and blower when the system pressure is high or low namely 25 WC. This avoids possible problems such as improper combustion, or the airflow problem by ensuring the right pressure of the HVAC system.
