Allen-Bradley 800H-JR2KB7B Selector Switch Maintained

Allen-Bradley 800H-JR2KB7B is a 30.5 mm, three-position selector switch with maintained action designed for panel mounting in industrial control panels. The unit features four standard contacts arranged as two normally open and two normally closed (2NO/2NC), and ships with a KB7 cam and a white standard knob for clear indication. The maintained operation holds a selected position until it is rotated to another position, making it suitable for mode or status selection in automation equipment. Rated for use in harsh environments, this 800H selector switch carries a NEMA 4/4X/13 rating when installed in a properly sealed enclosure. The JR2KB7B suffix identifies the 800H body, the KB7 cam, and the white knob variant in this 30.5 mm class; this configuration is widely cataloged by Rockwell Automation and distributors under the 800H-JR2B/800H-JR2KB7B family. Typical applications include control panels for conveyors, packaging lines, and other industrial automation where compact, reliable multi-throw switching is required.
