It features a white standard knob and KF4 cam, and integrates two contact blocks: the first block provides 1 normally open (NO) and 1 normally closed (NC) contact, while the second block provides 2 NO and 2 NC contacts, enabling flexible wiring and signaling across the four selectable positions. This maintained selector switch is suitable for applications such as mode selection, start\/stop sequencing, and interlocks in machinery, conveyors, and automation systems where the operator must lock a chosen position. The 800H family is built for rugged industrial use and is commonly paired with compatible 30 mm modular accessories to tailor contact configurations, mounting, and actuation to specific control schemes. KF4 cam compatibility ensures consistent interaction with the associated contact blocks and allows straightforward integration into existing 800H KF4-based assemblies. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New Surplus No Box","offer_id":51657523036462,"sku":null,"price":471.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_36774693-2029-475f-9bb2-2a1291f58251.jpg?v=1769469829","url":"https:\/\/plgautomation.com\/products\/allen-bradley-800h-nr2kf4b-selector-switch-4-position-maintained","provider":"PLG Automation ","version":"1.0","type":"link"}
