Worthington SWT309 Pressure Switch

The Worthington SWT309 Pressure Switch is a heavy-duty mechanical device that automatically monitors and switches pressure in industrial air and fluid systems within an adjustable 10–250 PSI range. Designed for industrial panel or equipment mounting, it supports air compressors, pumps, pneumatic control systems, hydraulic systems, and manufacturing process machinery that require automatic pressure regulation and equipment protection. Made in the United States, the SWT309 serves as a replacement maintenance and pressure-control upgrade for industrial systems and is commonly used in compressed air systems, industrial compressors, fluid transfer equipment, pneumatic automation machinery, and process control applications; it is compatible with air compressors, pumps, and pneumatic systems and has common replacements such as Square D 9013 Pressure Switch, Furnas Industrial Pressure Switch, and Ashcroft Adjustable Pressure Switch.
