Telemecanique ZB2-BD2 2-Position Maintained Selector Switch

The Telemecanique ZB2-BD2 2-position maintained selector switch provides reliable manual control for start/stop and mode selection in industrial automation panels. As part of the Harmony XB2 family, it features a 22 mm mounting diameter, a metal bezel, a black selector switch head, a black operator color, and IP65 protection, with a maintained left/right mechanical function. This two-position device is designed for use in packaging machines, conveyor systems, motor control centers, and automated production equipment where operator input must hold a chosen state until it is intentionally changed. It is commonly employed in operator panels, machine tools, material handling systems, and process control equipment for maintained position switching. Common replacements within Telemecanique's modular range include ZB2BJ2, ZB4BD2, and XB4BD21, reflecting compatibility with the Harmony XB4/ZB4 series for retrofit or expansion.
