Schneider Electric ZB4BG7 Push Button Switch 30mm

Schneider Electric ZB4BG7 is a metal, black XB4 head for a 22 mm Harmony key-selector switch, designed for panel mounting with a three-position, spring-return-to-center actuation. The head carries the key code 455 and is intended to be paired with the XB4 family’s actuators and contacts to create a keyed, lockable control suitable for machine safety, mode selection, or access-restricted operation on industrial equipment. With an IP66 protection rating and IK03 impact resistance, the unit is built to withstand dust and washdown environments, including exposure to water jets, in NEMA 4X settings. The 22 mm cutout accommodates compact panels while providing reliable tactile feedback and a secure feel for operators, making it a common choice for safety interlocks, start/stop sequencing, or tool-change procedures on conveyors, presses, and packaging lines. This description covers the switch head; for a complete keyed switch assembly, pair it with compatible XB4 actuators and contact blocks from Schneider Electric’s Harmony XB4 lineup.
