Aeromotive NS2-3086-00 SPDT Air Pressure Sensing Switch 0.27" W.C. Fixed Set Point

The Aeromotive NS2-3086-00 is a factory-calibrated, single-pole double-throw (SPDT) air pressure sensing switch with a fixed set point of 0.27" w.c. (inches water column). Built on the proven Cleveland Controls NS2 platform, this compact switch is engineered for OEM and HVAC applications requiring precise, repeatable pressure actuation at low pressure differentials.

Key Features:

• Fixed Set Point: Factory-calibrated at 0.27" w.c. — no field adjustment required
• SPDT Snap-Acting Switch: Single-pole double-throw contact arrangement for reliable switching at the set point
• Glass-Filled Polycarbonate Housing: Sturdy, contaminant-free construction for high accuracy and long-term reliability
• Integral Sensing Diaphragm: Housed within the compact body for responsive, accurate pressure detection
• Three-Terminal Quick-Connect: Features three male 90° spade terminals (1/4" x .032") for easy electrical connection
• Versatile Pressure Sensing: Capable of sensing positive, negative, or differential air pressure
• Color-Coded Ports: High and low pressure ports are color-coded for quick, error-free installation
• Compact Footprint: Integral foot bracket and optional metal mounting brackets included for flexible installation

The NS2-3086-00 is well-suited for use in furnaces, air handlers, heat pumps, and other HVAC or OEM equipment where airflow verification or pressure-based safety switching is required at a low, precise threshold. The snap-acting mechanism provides a narrow switching differential and low set point tolerance across a wide operating temperature range.
