Cleveland Controls NS2-0461-00 Pressure Switch

The Cleveland Controls NS2-0461-00 Pressure Switch is a mission-critical component engineered for precise differential air pressure monitoring in high-efficiency HVAC and refrigeration systems. Factory-calibrated at a 0.95" w.c. set point, this fixed-setting switch ensures proper airflow verification before allowing ignition or equipment operation. It serves as the direct replacement for RSS-495-461, providing a seamless drop-in solution for technicians servicing residential and commercial units. Built with a glass-filled polycarbonate housing, the NS2 series is designed for long-term stability in high-temperature environments. This model features a compression fitting for a leak-proof sample line connection and 90-degree male quick-connect terminals for fast electrical integration. Whether you are proving fan operation, monitoring filter pressure drops, or ensuring furnace draft, this switch provides the snap-action reliability required by OEM standards.

Key Benefits for Technicians

• OEM Compatibility: Engineered as the exact replacement for RSS-495-461, eliminating the need for field adjustments or bracket modifications.
• Superior Construction: The glass-filled polycarbonate body offers enhanced thermal stability and resistance to contaminants compared to standard plastic housings.
• Secure Connections: Equipped with a compression fitting to ensure a permanent, vibration-resistant seal on rigid or flexible sensing lines.
• Precise Calibration: Fixed 0.95" w.c. set point provides consistent pressure regulation and equipment safety without the drift common in adjustable models.
• Color-Coded Ports: Simplifies installation with clear identification of positive and negative pressure inlets to prevent vacuum/pressure plumbing errors.

Common Questions

Is the set point on the NS2-0461-00 adjustable?
No, this is a factory-calibrated fixed set point switch. It is set at 0.95" w.c. to meet specific OEM safety requirements and should not be tampered with in the field.

What is the proper mounting orientation for this switch?
For maximum accuracy and to prevent moisture buildup in the diaphragm, this switch should be mounted vertically with the sample line connections pointing downwards.

Can this switch be used for both positive and negative pressure sensing?
Yes, the Cleveland Controls NS2-0461-00 can sense positive, negative, or differential pressure. Connect the high-pressure side to the black port and the low-pressure/vacuum side to the gray port.
