Rheem-Ruud 42-101956-10 Pressure Switch Assembly W/-1.20" Water Column

The Rheem-Ruud 42-101956-10 Pressure Switch Assembly is one of the pressure control elements employed in HVAC systems. Pressure Switch Assembly is rated at -1.20" water column (WC) to meet the required pressure correction and protection of the system. As a pressure switch assembly, which operates by monitoring the level of pressure in the HVAC system, it activates or deactivates electric contacts located inside the assembly depending on changes in pressure. If the system pressure is above or below the -1.20” WC preset switch condition, then the switch will make or break the circuit to turn on or off particular components of the system.
