Trane SWT03410 Differential Pressure Switch

Product Description

The TRANE SWT03410 is a Style B differential pressure switch designed for use in HVAC systems where monitoring pressure differentials is essential to safe and reliable equipment operation. Differential pressure switches sense the difference in pressure between two points in a system and trigger a circuit open or closed when that differential crosses a set threshold. This type of switch is a standard-duty component used in furnaces, air handlers, and related HVAC equipment. Installation is typically performed by licensed HVAC technicians as part of routine service or system repair.

The SWT03410 is suited for residential and light commercial HVAC applications where a Style B form-factor differential pressure switch is required. It functions as an OEM-specification part within Trane-manufactured systems and is the type of component replaced during diagnostic service calls when pressure switch failure or lockout conditions are confirmed.

Key Features

• Style B differential pressure switch configuration for OEM-spec fitment
• Standard-duty construction appropriate for residential and light commercial HVAC systems
• Monitors pressure differential to protect equipment from unsafe operating conditions
• Direct Trane OEM replacement part

Compatibility

Designed as an OEM-style replacement differential pressure switch for Trane HVAC systems requiring a Style B differential standard configuration.

Installation Notes

Differential pressure switches are installed by licensed HVAC technicians. Before servicing, shut down the unit at the disconnect switch and allow system pressure to normalize. Verify electrical connections are de-energized before handling the switch or its wiring. Confirm the replacement switch matches the pressure differential rating of the original to avoid nuisance lockouts or unsafe operation.
