Supco SLP3560 Low Pressure Switch 35 PSI Open 60 PSI Close

The Supco SLP3560 is a reliable low pressure switch designed for HVAC and refrigeration applications. This automatic pressure control device monitors system pressure and actuates electrical contacts based on preset thresholds to protect compressors and system components.

Key Specifications:

• Opening pressure: 35 PSI - switch opens (breaks circuit) when pressure drops to this point
• Closing pressure: 60 PSI - switch closes (completes circuit) when pressure rises to this point
• Differential: 25 PSI between cut-in and cut-out points
• Designed for low-side refrigeration and air conditioning systems
• Factory preset and calibrated for accurate, consistent operation
• Durable construction for long service life in demanding environments

This pressure switch provides essential system protection by shutting down the compressor when refrigerant pressure drops too low, preventing damage from loss of charge or restricted flow. When pressure returns to normal levels, the switch automatically resets to resume operation. Commonly used in commercial refrigeration, air conditioning systems, and heat pumps.
