Low-Pressure SPST Switch, 25 PSI Open / 65 PSI Close

This low-pressure SPST switch is for HVAC technicians and service professionals who need to control equipment response to changing system pressure. It opens at 25 PSI on a pressure fall and closes at 65 PSI on a pressure rise for condenser fan cycling applications.

The switch has 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 operates across a 0 to 650 PSI pressure range, with 5,000 PSI burst pressure. Rated voltage is 24, 120, or 240 V at 50/60 Hz, with a 6 RLA and 36 LRA rating. Ambient operating temperature is 20°F to 176°F, and fluid temperature is 60°F to 250°F.

Key Features:

• 25 PSI open point: Opens the SPST circuit when pressure falls to 25 PSI.
• 65 PSI close point: Closes the circuit when pressure rises to 65 PSI for pressure-based cycling.
• Snap-acting sealed sensor: Provides a sealed sensing design with repeatable, stable set points.
• 1/4-inch SAE flare connection: Supports direct mounting with a female flare fitting and valve core depressor.
• 0–650 PSI operating range: Accommodates pressure monitoring within the stated operating range.

Choose this compact low-pressure switch when your HVAC control setup requires an SPST pressure switch with 25 PSI opening and 65 PSI closing points, a direct-mount flare connection, and a sealed sensor design.
