Copper technology

Membrane keypads with copper conductors

For optimum functionality and durability, we exclusively produce high-quality membrane keypads based on refined copper conductor tracks. This technology offers extremely high electrical and mechanical reliability as well as low conductor track resistance. Even complex electronic circuits can be directly integrated into the keypad and automatically assembled using SMD technology. Another advantage of this technology is that the foil connection cable can be bent with very small radii without the risk of breaking the conductor paths. This can be the decisive advantage over conventional conductive silver technology, especially when space in the housing is tight.

Mounting of the membrane keypad on an housing or front panel

After the feasibility check and the quotation phase, our specialists create a detailed release drawing (good for printing) with all relevant data of your membrane keypad. This drawing shows materials, color definitions (in RAL or Pantone) as well as the conductor paths and the electrical circuit diagram. During this phase, any changes you wish to make can be incorporated into the design without incurring any costs. After approval we start the production of the pilot series.

Ideally we like to combine our membrane keypads directly with one of our enclosures to a complete operating unit. If this cut is made directly by us, you can be sure that the membrane keypad has been assembled correctly and you will not have any rejects due to possible assembly errors. In addition, your stock-keeping is reduced.
