Schneider Electric ZB4 BA73133 Push Button Switch

ZB4BA73133 is a head for a triple-headed push-button in Schneider Electric’s Harmony XB4 lineup, designed for Ø22 mm mounting and to be paired with XB4 bodies to form a compact three-head operator. The assembly presents two green flush push-buttons on the sides and a central red STOP push-button that projects, with distinct markings: a right-arrow on one green head, a left-arrow on the other, and STOP on the center. This three-head configuration provides clearly separated functions in a single panel footprint, ideal for applications requiring directional control alongside an explicit stop in industrial equipment, such as conveyors, hoists, and machine control panels. The head is designed to integrate with Harmony XB4 modular control systems, enabling consistent operator interfaces and straightforward replacement across compatible machines. Because it is part of Schneider Electric’s Harmony family, it benefits from standardized 22 mm mounting and easily paired accessories, making it simple to upgrade or retrofit existing panels without replacing entire switch assemblies.
