Description
The Trane SWT03876 Low Pressure Switch is a pressure sensing control component designed to monitor refrigerant or air pressure and respond by opening or closing an electrical circuit when defined limits are reached at 35 PSI open and 55 PSI close. In HVAC systems used in chillers, heat pumps, and refrigeration circuits, it supports system control by detecting low-pressure variations and triggering appropriate operational response. It is typically installed on low-pressure lines using standard connection points for accurate sensing. The switching action contributes to stable control behavior, helping equipment maintain consistent operation during fluctuating load conditions.
