Cleveland Controls RFS-4001-030 Pressure Switch

The Cleveland Controls RFS-4001-030 Pressure Switch is a high quality that can be used in different HVAC systems. It serves as a protective and monitoring part, which controls system pressure and sounds an alarm or stops equipment when pressure levels are too high or low. This have found acts as a protection measure for the unit to avoid cases where damage is likely to occur to the HVAC system and therefore ensures its safety. The pressure switch works on a very simple mechanism. It has a diaphragm or bellows that is pressure-affected. In this case, the system pressure rises to a certain set point where the diaphragm or bellows changes its position to close a switch.
