Input systems

Overview of the KSG input system

It all depends on the right input. Here at KSG we have just the right input system for your application. Whether membrane and silicone keyboards or capacitive and resistive systems - our experienced engineers will be more than happy to support you in your project.

We manufacture input systems for customers in many sectors including measurement and control technology, medical electronics, automotive, telecommunications and printing. Our manufacturing expertise enables us to be your ideal partner for complete solutions for input systems and PCBs.

Your advantages

  • In addition to component production, we can also supply control units
  • Production of touch screens, membrane and silicone keyboards and membrane keyboards on PCBs
  • PCBs and control units from a single source
  • Various housing variations possible
  • Silicone keypads

For the individual illumination of buttons and surfaces of the input systems we offer the following possibilities allowing your products to glow:

  • LED spot lighting
  • LED area lighting

Colour gradients can be implemented using digital printing technology. Smaller quantities of decor variants can also be produced quickly and cost-effectively. Prototypes can actually be delivered to you within a few days 

An alphanumeric individualisation of films is just as possible as the printing of colour transparent windows.

Design of plug connections

  • Crimped sockets with housing
  • Crimped pins without housing
  • Solder contacts
  • Contact surfaces for direct plugging of zero insertion force (ZIF) connectors grid 1.00, 1.25, 1.27 and 2.54 mm possible, stiffening of the cable ends to the dimension required by the mating connector (generally 0.30 mm).

Kontaktflächen zum Direktstecken in Null-Kraftstecker (ZIF) Raster 1,00, 1,25, 1,27 und 2,54 mm möglich, Versteifung der Kabelenden auf das vom Gegenstecker erforderliche Maß (meist 0,30 mm). Die Kabelausführung muss in der Spezifikation angegeben werden.

The conductors of the output cable are electrically insulated with insulation coating. On request a reinforcement can be applied with a bonded film.

Solder resist masks 

  • Photosensitive solder mask systems
  • UV solder mask system: Screen printing
  • Colours: green, red, blue, glossy black, matt black, white, yellow


  • Chemical nickel/gold
  • Chemical tin
  • Electroplated nickel/gold
  • HAL or HAL lead-free
  • OSP
  • others on request

Additional printing 

  • Identification/assembly
  • Hole filler/through hole filler
  • Peelable solder mask 
  • Heatsink
  • Carbon

Edge plating 

The end faces of the PCB contour can be plated in order to improve the EMC protection of a PCB, make electrical contact with the housing of the module or meet increased cleanliness requirements. 

Edge metallisation

Milled plated through holes 

It is possible to produce application-specific components with so-called milled plated through holes. Due to the possibility of contact on the front side, the resulting PCBs can be soldered as components to another board (interposer).
