Membrane switches made of polyester

Exact cutting with CO₂ laser

Membrane switches must always remain operational under special conditions. Durability, soiling and water resistance as well as in sensibility regarding environmental influences are required features. Furthermore, they should be easy to clean and should offer a wide scope for different purposes by their compact design.

Specialised for cutting membrane switches

The laser cuts even mounted foil on a table concept especially developed for this purpose. For foil machining, laser systems are provided with a special table concept, the honeycomb. The beeswaxlike structure, from a thin aluminum foil, is very stable and allows a particularly good vacuum to form under the material.

Advantages of laser cutting for membrane switches:

  • Force-free effect due to contact-free cut
  • Exact dimensional accuracy, without wear
    • Without changing tools
    • Filigree contours up to 1/10 mm
    • Foil cables can be bridged

     

    The most important consideration when processing the individual layers is precision and matching the life-spans of the different materials. Above all, the production of the membrane switch should be economical. On the other hand, the products must display very specific properties and fulfill special functions.

    A few functional examples of complex foil assembly:

    • Flexible labeling options
    • Tactile snap discs
    • Electrical connections by flexible foil cables
    • Protective filter (e.g. against electrostatic charges)
    • Ergonomic surfaces
    • Integration of an LED layer
    • IP protection classes

    Precise cutting due to POSITIONplus

    Using camera recognition registration marks can be accurately read by the laser system and the position of the foil layers to be processed can be determined with precision. The intelligent analysis of the register marks also makes a compensation of the dimensions possible. This serves to optimize or align to the necessary dimensional accuracy.

    As a composite, most membrane switches can be e.g. contoured outwards, also after assembly.
