Series NS2™ is a family of reliable, economical switches with field-adjustable or factory-calibrated set points between 0.05″wc and 10″wc. They can sense positive, negative, or differential air pressure. These switches have a compact, glass-filled polycarbonate switch body with an integral snap switch. The narrow switching differential allows set point tolerance over a broad range of operating temperature and set point ranges. These low cost switches are especially sturdy and contaminant free for high accuracy and maximum reliability. NS2™ switches are the ideal solution for most high volume OEM applications.
