Industrial 642GEM2 Pressure Switch

Industrial CCS 642GEM2 pressure switch is a dual-snap, diaphragm-type device that monitors process pressure and closes or opens an electrical circuit at its preset point. It is rated for three common AC voltages—120 V, 250 V and 480 V AC—allowing compatibility with a wide range of industrial power systems. The unit features flange-mount construction and flying leads for straightforward installation and wiring in panels or on equipment housings. The 642GEM2 is specified up to 250 PSIG and is typically configured for a setpoint range from about 25 to 250 PSIG with DECR (decreasing) action, suitable for applications that respond to pressure drops. With Custom Control Sensors as the manufacturer, this model uses a dual-snap contact arrangement to provide reliable, repeatable switching across cycles in demanding environments. Common applications include sensing compressor or pump pressure, triggering control relays in hydraulic or pneumatic circuits, and protecting equipment by switching controls when the system pressure reaches the configured threshold. This model is cataloged under CCS 642GEM2 and is widely listed by distributors under the same designation, making it recognizable to buyers seeking a 120/250/480 VAC, dual-snap, flange-mount pressure switch for mid- to high-pressure monitoring tasks.
