Square D 9007DA11 Limit Switch Lever Arm Assembly

Square D 9007DA11 Limit Switch Lever Arm Assembly is a 2.5-inch (63.50 mm) long cast‑zinc lever arm designed for Square D 9007C heavy‑duty limit switches. The accompanying steel roller measures 0.75 inches (19.05 mm) in diameter with a 0.25-inch (6.35 mm) width, and the lever itself is about 0.31 inches (7.9 mm) wide, with the roller mounted in a front‑roller position to optimize actuation. This AW+C lever arm actuates a rotary operating head and is driven by a 30° cam, enabling precise triggering in compact installations. It weighs roughly 0.05 kg and is rated for operation from -29°C to 85°C, making it suitable for demanding industrial environments. The assembly translates mechanical movement into switch actuation, serving as a robust, metal‑to‑metal interface in applications such as machine guards, access doors, and safety interlocks where a durable lever and steel roller are required. Compatible with Square D 9007 series limit switches, particularly the 9007C configuration, this lever arm provides a proven solution for maintaining accurate actuation along the articulation path in control panels and equipment where reliable limit switching is essential.
