The Trane SWT03277 and SWT03274 pressure switches are essential components in maintaining the optimal performance of your Trane HVAC system. These pressure switches are designed to ensure the safe and efficient operation of your air conditioner, heat pump, or furnace.
The SWT03277 is a 650 close/500 switch, which means it operates at a 650 psig (pounds per square inch gauge) close pressure and a 500 psig open pressure.

The SWT03274, on the other hand, is a 75 switch, operating at a 75 psig close pressure and a 0 psig open pressure. This switch is typically used in the drain line of an air conditioner or heat pump to monitor the pressure and prevent water backflow into the system.
Both the SWT03277 and SWT03274 pressure switches are characterized by their durability and reliability. They are constructed with high-quality materials, including a brass body and a stainless steel diaphragm, to withstand the harsh conditions found in HVAC systems.
