The Schneider Electric ZB4BH03 is a green, flush pushbutton head designed for Ø22 mounting. This component functions as a push-push actuator, meaning it requires two distinct actuations to toggle between its on and off states, a common feature in control panels for sequential operations or latching functions. It is part of the Harmony XB4 series, known for its robust construction and modular design suitable for demanding industrial environments.
