Trane SWT1106 SPST Pressure Switch Overview
The Trane SWT1106 is a precision-engineered Single-Pole, Single-Throw (SPST) pressure switch designed for reliable pressure sensing and safety control in HVAC systems. With a setpoint of 0.28″ water column (w.c.) and a 1/4″ compression connection, this switch delivers accurate, repeatable performance in demanding residential and commercial applications.
Key Features
- Setpoint: 0.28″ w.c. (water column) for precise low-pressure detection
- Connection Type: 1/4″ compression fitting for secure, leak-free installation
- Switch Configuration: SPST (Single-Pole, Single-Throw) for straightforward circuit control
- OEM Trane replacement part — engineered to meet original equipment specifications
- Designed for integration into furnace, air handler, and other HVAC control circuits
- Durable construction for long service life in residential and light commercial environments
Application
The SWT1106 pressure switch is commonly used in gas furnaces and air handling units to monitor inducer draft pressure, ensuring the system operates safely within designed pressure parameters. When the required pressure is not achieved — indicating a blocked flue, failed inducer, or other fault — the switch opens the control circuit to prevent unsafe operation.
Why Choose the Trane SWT1106?
As a genuine Trane OEM component, the SWT1106 ensures compatibility and reliability when replacing a failed or suspect pressure switch in Trane equipment. Its 1/4″ compression connection simplifies field installation, and the SPST design integrates cleanly into standard furnace control board wiring.
