Within the 800H family, JR4B variants support several contact configurations, including 1 NO 1 NC and 2 NO 2 NC, and they can be paired with a KB7 cam for standard detented action. This unit is commonly used on control panels to implement state selections such as Hand–Off–Auto or Start\/Stop logic in industrial equipment, and several catalogs list it as discontinued within the legacy 800H lineup. As a 30 mm operator, it is compatible with standard 30 mm compact control switch assemblies in Rockwell Automation's catalog ecosystem.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51657525002542,"sku":null,"price":167.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_ca75f607-6e6b-4f85-a728-1eb451defec5.jpg?v=1769469842","url":"https:\/\/plgautomation.com\/products\/allen-bradley-800h-jr4b-selector-switch-assembly","provider":"PLG Automation ","version":"1.0","type":"link"}
