Duct Pressure Switches

Use these duct pressure switches to provide automatic starting and stopping for air-moving devices such as exhaust fans, humidifiers, air cleaners, duct heaters, and duct booster fans. These switches are activated by detecting positive, negative, or differential air pressure.

General Purpose

These general purpose duct pressure switches are commonly used in light-duty HVAC and residential applications.

Gold Contact

With gold contacts to help prevent corrosion and tarnishing, these switches are best for use in computer environments, direct digital control, or in low current and voltage applications.

Pneumatic Signal Output

Use these switches in settings where a pneumatic output signal is needed for actuation. They are commonly used in intrinsically safe applications where electricity cannot be used.
