High-Pressure SPST Switch, 425 PSI Open / 325 PSI Close

This high-pressure SPST switch is for HVAC technicians and service professionals who need to cycle a condenser fan based on system pressure. It opens on a pressure rise at 425 PSI and closes at 325 PSI to support pressure-responsive fan control.

The switch uses a snap-acting, hermetically sealed stainless steel sensor and a 1/4-inch SAE female flare fitting with a valve core depressor for direct mounting. It has a 0 to 650 PSI pressure range, 5,000 PSI burst pressure, and a 100,000-cycle life rating. Rated operation is 24/120/240V at 50/60 Hz, 6 RLA, and 36 LRA. Ambient operating temperatures range from 20°F to 176°F, while fluid temperatures range from 60°F to 250°F.

Key Features:

• Pressure-responsive switching: Opens at 425 PSI and closes at 325 PSI for condenser fan cycling based on pressure changes.
• SPST open-on-rise action: Provides a straightforward switching response as pressure increases.
• Direct-mount flare fitting: The 1/4-inch SAE female flare connection with valve core depressor supports direct installation.
• Hermetically sealed sensor: The stainless steel sensing element is sealed for pressure-control operation.
• Stable set point performance: Designed for repeatable, consistent pressure switching.
• Wide electrical compatibility: Rated for 24, 120, or 240V operation at 50/60 Hz.

Choose this compact high-pressure switch for condenser fan cycling applications requiring SPST open-on-pressure-rise operation, a 1/4-inch SAE female flare connection, and 425 PSI open and 325 PSI close set points.
