Rheem-Ruud 42-102056-25 Dual Pressure Switch

The Rheem-Ruud 42-102056-25 Dual Pressure Switch is a functional and safety part of the HVAC systems that maintains their proper work and prevents pressure problems. This dual pressure switch measures both high and low pressure in your heating or cooling equipment. The switch functions by monitoring the pressure in the system at all times. If pressure levels go beyond the set ranges or are lower than, the switch turns on, thus disconnecting the power that may cause harm or breakdown of the device from the source. After the pressure is back to normal the switch enables the system to resume normal functioning. Therefore when pressure is well maintained it helps in enhancing the operations of the system and the longevity of your equipment.
