Description
The Trane SWT02954 Low Pressure Switch Loss of Charge 1/4″ 8Amp is designed to monitor refrigerant pressure and protect equipment when pressure levels fall below the required operating range. The switch operates through a pressure-sensitive diaphragm that responds to reduced suction pressure and opens the electrical circuit when a refrigerant loss condition is detected. Applied in HVAC systems such as packaged units and air conditioning equipment, it is connected to the refrigerant circuit through a 1/4-inch fitting for pressure monitoring. This control action prevents compressor damage, limits operation during abnormal conditions, and supports safe system operation during refrigerant-related issues.
