The Harmony XB4/ZB4 metal series offers a wide range of 22mm complete devices such as push buttons, indicator lights and selector switches, right through to emergency stop switches. In addition, the modular design of the devices means that all components can be purchased as individual elements and optionally also for 30mm installation dimensions. This auxiliary switch block contains a universal white LED, which is compatible with any colored front element and requires a supply voltage of 24V ACDC. The universally applicable white LED module thus ensures easier selection in the ordering process and simplified warehouse management. Suitable for international use due to the large number of existing product standards and certifications. Thanks to the Green Premium environmental label, you can receive detailed information on material content, environmental impact and circular economy that supports your sustainability goals.
