Cleveland Controls RFS-4001-058 Pressure Switch

The Cleveland Controls RFS-4001-058 Pressure Switch is essential for use in different HVAC systems. This switch measures the pressure of the system and sounds a signal when the pressure gets to a certain level. It works on the diaphragm deflection theory. When the system pressure rises, it pushes down on a diaphragm in the switch which causes it to bend. This deflection operates several electrical contacts, making or breaking the circuit to regulate related apparatus. They find extensive use in different types of HVAC systems such as air compressors, refrigeration equipment, and air dryers. It is essential to protect equipment against overpressure conditions that may cause equipment failure or damage.
