This small mechanical component serves as the actuating interface between a moving machine element and the limit switch body, converting physical contact into a switching action. The roller measures 1.5 inches in overall length with a 0.25 inch diameter and a 0.25 inch face width. The body is cast zinc and the roller itself is steel, providing durable performance in standard industrial control applications. Electricians and industrial maintenance technicians install this part during limit switch repair or actuator assembly replacement.\u003c\/p\u003e\n\u003cp\u003eThis lever roller is suited for use in residential and light commercial automation, conveyor systems, door position sensing, and general industrial machine control wherever a limit switch actuator must be replaced or upgraded. It is intended for use with compatible SQUARE D limit switch bodies as a service replacement or spare component. Its compact form factor allows installation in tight actuator mounting arrangements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCast zinc body construction for corrosion resistance in standard indoor industrial environments\u003c\/li\u003e\n  \u003cli\u003eSteel roller for wear resistance at the contact point\u003c\/li\u003e\n  \u003cli\u003e1.5 inch overall length fits standard lever-arm limit switch actuator positions\u003c\/li\u003e\n  \u003cli\u003e0.25 inch roller diameter with 0.25 inch face width for precise actuation\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.07 pounds, minimizing added load on the switch arm\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 SQUARE D limit switches requiring this actuator accessory type.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified electrician or industrial maintenance technician. De-energize and lock out the control circuit before removing or replacing any limit switch component per NFPA 70E lockout\/tagout procedures. Verify the roller diameter and face width match the original actuator specification before installation. Do not over-tighten the roller mounting hardware, as this can deform the zinc body and affect actuator travel.\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\u003eRoller Diameter\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: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions (H x W x L)\u003c\/strong\u003e: 0.6 x 1 x 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 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: 7A1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51542441197874,"sku":"7A1","price":38.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eef1d1275defa18caff619884ec5b0a3.jpg?v=1785900618","url":"https:\/\/voomisupply.com\/products\/square-d-7a1-limit-switch-lever-roller-cast-zinc","provider":"Voomi Supply","version":"1.0","type":"link"}
