Rheem-Ruud 42-101104-09 Dual Pressure Switch

The Rheem-Ruud 42-101104-09 Dual Pressure Switch is one of the components of HVAC systems that are employed in the measurement of high pressure and low pressure. It is made of a rigid plastic and it serves to ensure the HVAC equipment is operating effectively and safely by switching between the two pressures. It turns the compressor on or off depending on specific pressure characteristics of the refrigerant gas; high and low. It works on the principle of pressure of the refrigerant in the circuit. The device increases the longevity of the HVAC system since pressure regulation damages the compressor and other parts of the system. This switch is used in refrigeration machines mainly because of the availability of the dual pressure control.
