Trane SWT4049 High Pressure Switch

The Trane SWT4049 is a high pressure switch, this is safety device that is used in many HVAC applications. It plays the role of pressure controlling element of the system, checking the pressure of refrigerant inside it. When the pressure rises beyond a specified safe level, the switch acts by breaking the electrical circuit. This helps protect the system from running at high pressure to avoid development of faults within the system. The Trane has several advantages for your HVAC equipment. Therefore, besides protection from pressure-related issues, it improves the level of protection and the system reliability.
