Square D 7A1N Limit Switch Lever Roller Cast Zinc

Product Description

The SQUARE D 7A1N is a replacement lever roller designed for use with industrial limit switches. 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.

This 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.

Key Features

• Cast zinc body provides durable, lightweight construction
• Nylon roller reduces friction and wear during repeated actuation cycles
• 1.5-inch overall length with 0.25-inch diameter for precise fitment
• 0.25-inch face width for consistent contact geometry
• OEM-style replacement for compatible SQUARE D limit switch assemblies

Compatibility

Designed as an OEM-style replacement lever roller for use with compatible SQUARE D limit switches.

Installation Notes

Installation 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.
