High-Pressure SPST Switch, 350 PSI Open / 250 PSI Close

This high-pressure SPST switch is for HVAC professionals who need to cycle condenser fans in response to system pressure. It opens on a pressure rise at 350 PSI and closes at 250 PSI to support pressure-based fan control.

The switch uses a snap-acting, hermetically sealed stainless steel sensor and a 1/4 in. SAE female flare fitting with 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. Electrical ratings are 24, 120, or 240 V at 50/60 Hz, with 6 RLA and 36 LRA. Ambient operating temperature is 20°F to 176°F, and fluid temperature is 60°F to 250°F.

Key Features:

• 350 PSI open point: Opens the circuit on a pressure rise at 350 PSI for defined fan-cycling control.
• 250 PSI close point: Closes the circuit at 250 PSI to restore operation as pressure drops.
• SPST snap action: Provides a direct open-on-pressure-rise switching function.
• Sealed stainless steel sensor: Combines a hermetically sealed sensor design with stainless steel construction.
• 1/4 in. SAE flare connection: Supports direct mounting with a female flare fitting and valve core depressor.
• 0 to 650 PSI range: Accommodates applications operating within the stated pressure range.

Choose this switch for pressure-based condenser fan cycling where a 350 PSI open point, 250 PSI close point, SPST operation, and 1/4 in. SAE female flare connection match the system requirements.
