High-Pressure SPST Switch, 450 PSI Open / 250 PSI Close

This high-pressure SPST pressure switch is for HVAC service professionals and technicians working with condenser fan cycling controls. It opens on a pressure rise at 450 PSI and closes at 250 PSI to support pressure-based fan cycling operation.

The switch has a 1/4 in. SAE female flare fitting with a valve core depressor for direct mounting. Its snap-acting, hermetically sealed stainless steel sensor operates across a 0 to 650 PSI pressure range and has a 5,000 PSI burst pressure. It is rated for 100,000 cycles and 24, 120, or 240 V at 50/60 Hz, with 6 RLA and 36 LRA ratings. Ambient operating temperature is 20°F to 176°F, and fluid temperature is 60°F to 250°F.

Key Features:

• 450/250 PSI switching: Opens at 450 PSI on pressure rise and closes at 250 PSI for defined pressure-based control action.
• SPST snap action: Provides a quick switching response as pressure rises.
• Direct-mount flare connection: The 1/4 in. SAE female flare fitting with valve core depressor supports direct installation.
• Hermetically sealed sensor: Uses a stainless steel sensor with set point repeatability and stability.
• Broad electrical compatibility: Rated for 24, 120, and 240 V operation at 50/60 Hz.
• 100,000-cycle rating: Rated for repeated switching operation over 100,000 cycles.

Choose this switch when your pressure-control setup requires an SPST device that opens on pressure rise at 450 PSI and closes at 250 PSI, with a direct-mount 1/4 in. SAE flare connection.
