Schneider Electric 9001-C42 On Off Control Switch

Schneider Electric's Square D 9001-C42 On/Off Control Switch is a legacy ON/OFF selector switch in the 9001 control family, designed for use in electrical control panels and machine-control circuits. This particular model is listed as discontinued by the manufacturer, making it primarily relevant for retrofits or replacements in existing installations that originally used 9001-series devices. Typical applications include simple on/off control in industrial automation and panel-building projects where a 9001-compatible switch is appropriate, with field replacement options often turning to remaining stock or compatible 9001 components.
