Customer-specific input systems
No matter what size, colour or design - our membrane keypads are manufacturedto our customers’ exact specifications. Matt, satin-frosted or lustrous front mem-brane? With or without a clear screen? With or without
tactile action point?
You choose and, depending on the model, it comes with a safety chamber for
each individual snap dome. This prevents the metal domes from slipping, soimproving quality considerably. By the way: we also develop and produce inputunits with short-stroke keys and corresponding front membranes.
Keypads with integrated electronics
ProfiLine technology
The input unit (the membrane keypad or the short-stroke keys) and the matching
electronics are on the same carrier — without any fault-prone and expensive
plug-in connectors. Here, too, the customer decides whether the carrier is toconsist of a single PCB (FR4 etc.) of different thicknesses or of a flexible membra-ne. One important advantage is that electronic modules can be SMD-inserted,
soldered and plated-through without risk to the process as a whole. This means
that they do not have to be glued in, as is usually the case with conductive silverapplications. Even with maximum packing density, the modules easily adapt tothe enclosure geometry. With ProfiLine, our latest membrane keypad, the usergets much more than a mere input element. Made of
deep-drawn acrylic glass, the keys ensure enhanced tactilecontact. Plus, there are no limits to individual key design.
Mitglied in derFachgemeinschaft Tastaturen Keypads for use in the dark
In the past, if you also wanted to use keypads in the dark, then you often hadto accept a compromise. For example, LEDs only produce a point of light, and
the well-known problems of using an integrated EL membrane (short opera-ting life, low level of mechanical stability, high cost, EMC problems) mean thatthey are too complicated and unreliable in use. Our new back-lit Profiline
technology offers an effective solution to this problem. The light passesthrough a hole in a special snap dome into the integrated acrylic inlay, whereit is distributed as required. The optimised pressure point functions exactly as
before, and the keys can even light up individually. 14
