{"product_id":"allen-bradley-800mr-jh2blas-small-round-3-position-selector-switch","title":"Allen-Bradley 800MR JH2BLAS Small Round 3 Position Selector Switch","description":"\u003cdiv\u003e\u003cp\u003eAllen-Bradley 800MR-JH2BLAS is a compact, round three-position selector switch in the 800MR family, engineered for rugged industrial control panels. The suffix S identifies a spring-return operator option, a variant that provides spring-back action after a selection. This 3-position unit is used to manually select among three discrete states in automation systems, enabling operators to switch between modes or control states on machinery, conveyors, and other equipment. The 800MR family is recognized for its durable round form factor and reliable operation in demanding environments, with configurations designed to fit standard panel cutouts and mounting interfaces. For exact compatibility, verify with Rockwell Automation catalogs or an authorized distributor to confirm the correct knob style, cam, and terminal arrangement for your installation; while the core function is simple, matching the proper operator type, position mapping, and mounting interface is essential to maintain safe, predictable control behavior. This model, as part of the 800MR line, is typically used in panel-mounted control circuits where a dedicated three-position manual selector is required to govern manual override, mode selection, or standby-to-run transitions in industrial equipment.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51657249259822,"sku":null,"price":65.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_4f7e6c76-a8e0-4ec2-a4e4-b869ddec1ea6.jpg?v=1769467166","url":"https:\/\/plgautomation.com\/products\/allen-bradley-800mr-jh2blas-small-round-3-position-selector-switch","provider":"PLG Automation ","version":"1.0","type":"link"}
