Trane SWT4155 Low Pressure Switch

The Trane SWT4155 Low-Pressure Switch is an essentialpart of HVAC systems, which is aimed at controlling pressure in the system. This switch is 4.7” in length and is usually applied to air conditioners and heat pump equipment. It works by sensing the pressure and gives an output when the pressure level falls below a certain minimum pressure required to ensure the proper functioning of the system and avoid any catastrophic failure of the compressor. The advantages of the Trane include increased dependability of the system, higher efficiency, and longer equipment durability. By keeping pressure under control it maintains constant climate conditions and prolongs the time between necessary repairs.
