SQ Adjustable Low-Pressure Switch
Perfect for first-round designs, the field-adjustable SQ low-pressure switch meets NEMA 4 & 13 standards, combining fingertip adjustability with visual calibration with a maximum operating pressure of 250 PSI. With three adjustment ranges 2–120 PSI, a brass base material, and a long-life elastomer diaphragm to prevent creeping, this snap-action pressure switch is ideal for testing and prototyping. Once the exact parameters for a particular application are determined, the next design iteration could be built with a factory-set version.
