Cleveland Controls NS2-1199-00 Pressure Switch

The Cleveland Controls NS2-1199-00 Pressure Switch is reliable and can be used in different HVAC systems. This switch measures system pressure and sends an electrical signal when the pressure in the system goes up to certain level. This signal can then be used to switch on or off other parts of the HVAC system, for instance, compressors, fans, or valves. It has a diaphragm which is capable of being affected by pressure. When the system pressure goes high than the set value, the diaphragm moves and opens a microswitch within the unit. This closure of the micro switch breaks an electrical circuit and the signal is then relayed to the correct control system.
