Ranco O10-1831 Low Pressure Control Switch 10-100 PSI SPST

The Ranco O10-1831 is a low pressure control switch designed for HVAC and refrigeration applications requiring reliable pressure monitoring and control. This single-pole single-throw (SPST) switch operates with close-on-rise (high) and open-on-fall (low) functionality, making it ideal for low-side pressure safety and control circuits.

Key Features:

• Pressure range: 10 inches vacuum to 100 PSIG
• Differential pressure setting: 10 PSI to 40 PSI adjustable
• 1/4 inch male flare connector for easy installation
• SPST switch configuration: closes on high pressure, opens on low pressure
• Durable construction for commercial and industrial refrigeration systems
• Factory calibrated for accurate pressure control

This pressure control is commonly used in air conditioning, refrigeration, and heat pump systems to protect compressors from low-pressure conditions. The adjustable differential allows for precise tuning to match specific application requirements, while the male flare connection ensures leak-free installation in standard refrigeration piping.
