Schneider Electric's Square D GBR-2 pressure switch is a Class 9012 electro-mechanical diaphragm switch that provides two adjustable setpoints across a 20 to 675 psi range. It uses single-pole, double-throw (SPDT) contacts and is rated for 120–600 VAC, enabling reliable on/off control for pumps, compressors, and other pressure‑driven equipment. As part of the 9012G family, the GBR‑2 variant supports a maximum pressure rating up to 2000 psi and is designed for industrial environments requiring two switching thresholds and durable diaphragm sensing.
