Schneider Electric 9001KA1 Push Button Switch

Schneider Electric’s 9001KA1 is a 30 mm push-button contact block that serves as an accessory to Harmony 30 mm push-button operators in the 9001K family (Types K, SK or KX). It provides a second contact set—one normally open (NO) and one normally closed (NC)—to support signaling, interlock, or status-feedback circuits alongside the main operator. Wiring is standardized: NC terminals are labeled 1 and 2, while NO terminals are labeled 3 and 4. The block includes cable clamps and is finger-safe, designed for secure termination and safer field replacement in control panels. As an auxiliary contact block, 9001KA1 is intended to be paired with compatible 30 mm push-button units to expand control logic in industrial equipment such as machines, conveyors, and safety systems, without replacing the primary switch. The part number 9001KA1 uniquely identifies this two-contact accessory within Schneider Electric’s Harmony 30 mm push-button ecosystem.
