Product Description
The Dwyer 1640-2 Floating Contact Null Switch is designed for precise control of air and non-combustible, compatible gases within HVAC systems. This SPDT switch features a unique floating contact mechanism that is activated at two preset points, avoiding any switching action between these set points.
Efficient for managing air velocity and volume in duct systems.
Equipped with a visible set point indicator for easy operation and troubleshooting.
Robust design with a diaphragm in vertical placement ensures durability and performance reliability.
Product Highlights
This switch is ideal for damper positioning and duct air control, providing accurate responses to pressure changes. It is engineered to operate within temperature limits of -30 to 110 degrees Fahrenheit and pressure limits up to 25 psig.
