Common industries include packaging, food processing, and manufacturing plants where it is essential to prevent access to moving parts during operation. This tongue interlock switch is typically installed in safety circuits to ensure machines cannot start unless all guards are properly closed, or to stop operation if a guard is unexpectedly opened. With its MBB contact scheme and reliable plastic enclosure, the 440K-T11146 is a trusted choice for both new installations and upgrades to existing safety systems, reducing the risk of operator injury and supporting compliance with global machinery safety standards.\n\n\u003ch2\u003eRelated Resources\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/\" target=\"_blank\"\u003eLeadTime.ca – Industrial Automation Components \u0026amp; Repair Services\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/collections\/allen-bradley\" target=\"_blank\"\u003eView All Allen Bradley Products\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/blogs\/learning-center\/examples-of-industrial-automation-control-systems\" target=\"_blank\"\u003eExamples of Industrial Automation and Control Systems\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/products\/allen-bradley-194e-sy\" target=\"_blank\"\u003eAllen Bradley 194E-SY Disconnect Switch\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/products\/allen-bradley-1609-d600n\" target=\"_blank\"\u003eAllen Bradley 1609-D600N UPS Backup Power Supply\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Allen Bradley","offers":[{"title":"Default Title","offer_id":47870768742699,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0837\/4671\/7995\/files\/Leadtime_b707a067-21fc-4b4a-87dd-639303ca21c5.png?v=1723532558","url":"https:\/\/leadtime.ca\/products\/allen-bradley-440k-t11146","provider":"LEADTIME","version":"1.0","type":"link"}
