Square D 9007HA1 is an adjustable lever-arm accessory for 9007C heavy-duty limit switches, designed to tailor actuator travel for safety guards and automation interfaces. It uses an AW+C lever configuration with an arm length adjustable from 0.88 inches to 4 inches, and a steel roller with a 0.63-inch outside diameter and 0.25-inch width to provide smooth actuation. The lever delivers rotary head movement actuated by a 30-degree cam and is intended for standard-environment installations, expanding reach and compatibility when mounting 9007 limit switches.
