Rheem-Ruud 42-102072-25 Dual Pressure Switch

The Rheem-Ruud 42-102072-25 Dual Pressure Switch is safety device that controls pressure in heating and cooling systems. It is intended to cope with high and low pressure which enable your heating or cooling equipment to work properly and without wastage of power. The switch works in a way that it measures pressure within the system at all given times. If the pressure goes up or down and hits the limit of the safe operating range the switch turns off the power hence eliminating any possible harm or other complications. The switch allows normal functionality to be resumed once pressure levels have been brought back to their normal ranges. This is compatible with many Rheem and Ruud HVAC models and offers significant advantages that include increased system safeguard, compressor harm prevention, and better operational dependability.
