Schneider Electric XB4BD21 Selector Switch

The Schneider Electric Harmony XB4BD21 is a 22 mm metal selector switch in black that provides two maintained positions and a single normally open contact, with the two positions separated by 90° of rotation for clear on/off or mode-selection signaling. Built for rugged industrial environments, the metal housing measures about 46.5 mm high by 70 mm long by 30 mm deep and weighs around 90.7 g, making it compact enough for dense control panels. The 22 mm diameter actuator accepts multiple operator profiles, including long-handled or standard-handled variants, and supports versatile wiring with termination options such as screw clamp, connector, Faston, or spring-terminal connections. This stay-put selector is designed for panel-mount use in control circuits and machinery, delivering reliable manual control in applications like start/stop or mode selection. Electrical ratings for this XB4BD21 model are listed up to 600 VAC and about 1.2 A, reflecting Schneider Electric’s typical specifications for 22 mm metal XB4 selectors. The XB4 family combines robust construction with a compact footprint, enabling straightforward integration into a wide range of industrial control panels and equipment.
