Schneider Electric XB2MG21 Selector Switch Without Key

The Schneider Electric XB2MG21 (MPN XB2MG21) is a 30 mm panel-mounted selector switch from the Telemecanique XB2-M family, offering two maintained positions for secure machine control and operating mode selection in industrial automation systems. This key-operated device features left and right key withdrawal positions and a single changeover contact (1 C/O), enabling authorized personnel to enable or disable specific functions on control panels, conveyors, pumps, or machinery. It mounts on a panel through a 30 mm opening and uses screw terminals, a chromium-plated metal bezel, and a black operator for durable, visible operation in harsh environments, with an operating range of -25 °C to +70 °C. The XB2MG21 complies with IEC 60947-1, IEC 60947-5-1, and IEC 60947-5-4, making it suitable for industrial control panels, manufacturing lines, packaging equipment, and other automation systems requiring keyed mode selection and secure enable/disable control.
