The TRANE SWT3023 is a low pressure switch designed for HVAC systems. This device uses a single pole, single throw (SPST) configuration and operates within a pressure range of 25 psi to 45 psi. It monitors pressure levels. When pressure falls outside of the specified range, the switch will activate or deactivate attached equipment, helping to maintain system efficiency and protect against possible damage due to low pressure conditions.
