Popular fields of use

The many benefits of membrane keyboards make them a real all-rounder. The keyboards make a crucial contribution to preventing costly downtimes at the human-machine interface. Membrane keyboards can also be operated precisely and this reduces operating errors, even in the toughest settings. The keyboards have been a reliable technical standard item in industry for many decades. This includes the following sectors:
  • Engineering, plant and apparatus construction
  • Aerospace technology
  • The automobile industry
  • The food and drinks industry
  • The recycling industry
  • The metal industry

However, membrane keyboards are also extremely popular in the medical sector. The lack of grooves and notches between the keys means that it is impossible for impurities to settle there. This facilitates hygienic usage. All the models can also be cleaned quickly and simply without any problems.
