Overview
The Square D Harmony XB5 Key Switch Selector Head (Model ZB5AG08) is a non-illuminated, three-position selector head for use with Schneider Electric XB5 series 22mm pushbutton and selector switch assemblies. The Ronis 455 key mechanism provides access control functionality, requiring the key to operate the selector. The spring-return-from-right-to-center action allows momentary right-position activation while the left position retains the key for withdrawal, making it ideal for machine control and safety interlock applications.
