Trane SWT2281 SPST Pressure Switch 650 Open / 500 Close PSI

Description

Trane SWT2281 SPST Pressure Switch Overview

The Trane SWT2281 is a Single-Pole, Single-Throw (SPST) pressure switch engineered for reliable high-pressure circuit protection in HVAC and refrigeration systems. Designed to OEM Trane specifications, this switch provides accurate and repeatable pressure-activated switching to safeguard compressors and system components from damaging overpressure conditions.

Key Specifications

• Part Number: SWT2281
• Switch Type: SPST (Single-Pole, Single-Throw)
• Open Set Point: 650 PSI
• Close Set Point: 500 PSI
• Function: Opens circuit on pressure rise at 650 PSI; closes circuit on pressure drop at 500 PSI
• OEM Trane replacement part

How It Works

The SWT2281 monitors system refrigerant or fluid pressure and interrupts the circuit when pressure reaches the 650 PSI open threshold. Once pressure drops back to 500 PSI, the switch closes and restores the circuit. This differential action prevents short-cycling and provides stable, dependable protection for compressors and associated equipment.

Application

• High-pressure cutout protection for HVAC and refrigeration systems
• Direct OEM replacement for compatible Trane equipment
• Suitable for use in commercial and light industrial HVAC applications

Why Choose the Trane SWT2281

As a genuine Trane OEM component, the SWT2281 ensures fit, form, and function that aftermarket alternatives may not match. Proper pressure switching helps extend compressor life, maintain system efficiency, and reduce costly service calls. Trust Jackson Systems to deliver the OEM parts your Trane equipment demands.
