Square D 9001 C-46 Selector Switch Pushbutton Station

Square D Harmony 9001C-46 Off-On selector switch pushbutton station is a 30 mm, panel-mount control that combines a two-position OFF/ON selector with a built‑in pushbutton in a single 9001-series operator. In this configuration, the device provides a 1 normally open / 1 normally closed contact arrangement, enabling straightforward start/stop or mode-selection functions in industrial equipment. Some listings identify this model as a NEMA 1 enclosure unit, suitable for indoor panel installations. As part of the Harmony 9001 family, the 9001C-46 is designed to align with other 30 mm Square D components for custom control stations, allowing integration with compatible pushbuttons and selector heads. Typical applications include machine start/stop control, manual/automatic mode selection, and compact control stations on conveyors, packaging lines, and processing equipment where a dedicated OFF position aids clear shutdown states.
