It serves as the mechanical actuator component that makes physical contact with a target or cam, triggering the switch to open or close a circuit. The body is cast zinc construction measuring 1.5 inches in overall length and 0.25 inches in diameter, with a nylon roller and a 0.25-inch face width. This part is installed by electricians and industrial maintenance technicians in control panel, conveyor, or machinery applications where limit switch actuation is required.\u003c\/p\u003e\n\u003cp\u003eThis lever roller is intended for limit switch assemblies in industrial and commercial control systems. It is commonly found in applications involving conveyor lines, machine tool positioning, automated door systems, and similar electromechanical setups where a physical actuator is needed to trigger switching action. The compact profile and nylon roller material make it suited for moderate-duty actuation across a range of equipment environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCast zinc body provides durable, lightweight construction\u003c\/li\u003e\n  \u003cli\u003eNylon roller reduces friction and wear during repeated actuation cycles\u003c\/li\u003e\n  \u003cli\u003e1.5-inch overall length with 0.25-inch diameter for precise fitment\u003c\/li\u003e\n  \u003cli\u003e0.25-inch face width for consistent contact geometry\u003c\/li\u003e\n  \u003cli\u003eOEM-style replacement for compatible SQUARE D limit switch assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement lever roller for use with compatible SQUARE D limit switches.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed electrician or qualified maintenance technician. De-energize and lock out the control circuit before removing or installing any limit switch component in accordance with applicable NFPA 70E lockout\/tagout procedures. Verify the replacement roller dimensions match the existing hardware before installation. Inspect the mounting arm and pivot hardware for wear before reassembling the limit switch actuator.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFace Width\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Cast Zinc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRoller Material\u003c\/strong\u003e: Nylon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SQUARE D\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7A1N\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51538356371762,"sku":"7A1N","price":23.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d0fcfc2f03da6b95a4e3262bae7c5430.jpg?v=1785823713","url":"https:\/\/voomisupply.com\/products\/square-d-7a1n-limit-switch-lever-roller-cast-zinc","provider":"Voomi Supply","version":"1.0","type":"link"}
