Trane SWT3541 Pressure Switch Open 2.15" WC Close 2.4" WC

The Trane SWT3541 is a Pressure Switch that is an essential part of HVAC systems and is responsible for safety and stability. This switch is designed to open at -2.15” WC and close at -2.4” WC and therefore controls the pressure in the system. It is a single pole of 4.9” in length, and the terminal is quick connect type, 1/4 x 0.032”. They avoid situations where the airflow is limited or where the venting problems are more severe from having an impact on the system. Since it helps maintain the efficiency and longevity of the HVAC system, this switch enables the detection of pressure changes.
