Selection Notes
Unmarked and black, the XB4BA21 is the default general-purpose push button in the XB4 metal range. Specify the marked I/O or arrow-symbol variants in the same range where the panel needs a labelled start, stop or jog function instead of a plain button, or switch to a 1 NC version where the control logic requires a normally-closed contact.
