Rheem 42-101955-02 Pressure Switch Assembly SPST Water Column 0.40"

The Rheem 42-101955-02 Pressure Switch Assembly is a crucial component needed in HVAC systems to perform as they are supposed to. This pressure switch has a SPST arrangement or otherwise known as a switch that shorts the two terminals. Its design is such that it is intended to operate at a pressure of 0. 40 inches of water column still can be maintained in this type of reactor. This pressure switch operates with monitoring the air pressure of the HVAC system and controlling the electrical circuits depending on that pressure. It means that when the pressure goes high or low the circuit is opened or shut by the controller. It is at the 0.40 WC set point the integrity of the system is enhanced.
