Allen-Bradley 800MR-JX2B 3 Position Selector Switch

Allen-Bradley 800MR-JX2B is a three-position selector switch from Rockwell Automation’s 800MR family, designed for panel-mounted control in industrial equipment. The JX2B variant provides a maintained, non-illuminated selector action with a B cam configuration and supports standard-key or no-key options depending on the kit. This switch is typically used to select among three discrete circuit states—common in start/stop, mode selection, or sequencing in automation panels—and is commonly paired with corresponding contact cartridges and mounting hardware to suit left- or right-hand installations. The 800MR family is known for robust mechanical quality and reliable actuation in factory environments, with accessories such as knobs, bezels, and mounting rings available to tailor the fit to your control enclosure. Ideal for applications where a durable, tactile control element is required to indicate clear, physical selection of machine operating modes or process steps.
