Product Information

The Harmony XB4 metal range of modular control and signalling units combines simplicity of installation, flexibility, and robustness. This range meets the requirements of the majority of industrial applications.
These units are either complete products or separate components for customer assembly.


This range of XB4 includes:

  • Pushbuttons, selectors/key switches, emergency stop functions or multiple-headed pushbuttons designed for parameter settings, adjustments, and start/stop control of machines and installations
  • Pilot lights, illuminated pushbuttons, illuminated selector switches, and
  • illuminated Emergency stop functions designed for visual signalling
  • The installation process is both simple and quick:
  • Mounting by single installer (self-maintaining of the head in its cut-out)
  • Clip-together component system (head, body, contact blocks, and LED)
  • Attached using a single locking screw
  • Anti-loosening system for screw clamp terminals on contact blocks
