Rheem 42-101233-81 SPST Pressure Switch 0.35" PF

The Rheem-Ruud 42-101233-81 Pressure Switch plays an essential role in the HVAC systems in that it prevents pressure build-up and monitors the pressure. This single-pole single-throw switch has a pressure range of 0. 35” of water column, and is constructed from robust silicone rubber tubing in order to provide reliability. This pressure switch is normally found in Rheem heating and cooling systems to prevent the pressure from rising beyond the standard limit. In other words, it functions based on the idea of switching On or Off the HVAC system if the pressure becomes a problem to the system or if the system becomes inefficient.
