Rheem-Ruud 42-101956-09 SPST Pressure Switch Assembly W/-1.0" Water Column

The Rheem-Ruud 42-101956-09 SPST Pressure Switch Assembly is used to know the pressure level or to control the pressure within the Heater and AC systems. This switch assembly is designed to detect pressure change with a rating capability of -1. 0" water column (WC), to obtain well control and high repeatability. Their construction is compact and robust at the same time which allows their application in various heating and cooling processes. This pressure switch assembly works in a way that the pressure in the working system switches the electrical contacts depending on set pressure parameters. For instance, the 42-101956-09 is typically designed to respond to negative pressure changes in order that the system performs within safe and ideal condition.
