Schneider Electric Square D 9012-GCW1 Pressure Switch

Schneider Electric Square D 9012-GCW1 pressure switch is a rugged industrial control device that automatically toggles electrical circuits as system pressure crosses setpoints. The 9012GCW1 variant features SPDT (single-pole, double-throw) contacts for reliable switching of pumps, compressors, or other pneumatic and hydraulic equipment, with adjustable differential to fine-tune response. Rated for up to 480 VAC and 10 A, it handles motor loads typical of industrial environments. The unit operates over a pressure range from 20 to 1000 PSIG, suitable for a wide variety of fluid, gas, and steam applications, with a 1/4-18 UNF internal-thread pressure connection for a compact interface. Its enclosure is designed for challenging environments, NEMA 4/4X/13, enabling installation in wet or dirty locations. Inside, a 440 stainless steel piston works with a Viton fluorocarbon diaphragm to resist wear and provide stable switching across temperature and time. The GCW1 designation identifies this specific configuration within the 9012G pressure-switch family, and the device is UL, CSA, and CE listed for broad electrical compatibility.
