N&H Laboratory

In our laboratory, we carry out technical tests and analyzes. Measurements on our own products are free of charge for our customers.
Upon request, we also peform technical analysis for third-party products.


1. Electromechanically Testing


  • Force-Travel performance of control elements (e.g. silicone rubber keypads, membrane switches, tact switches, micro switches etc.)
  • Life Cycle of control elements
  • Abrasion Test of coated and printed surfaces (e.g. legends and coatings of keys, front panels, parts of housings, etc.)
  • 2D / 3D measuring microscope
  • Pressure / Pull Force measurements for checking the strength of material connections, operating forces on control elements (buttons, switches), pull-off performance of films
