Membrane keyboards were first developed in the 1980s when it became possible to print conductive inks on to a flexible substrate such as polyester. Since then, Membrane keyboard technology has evolved and they are now used in many applications such as security access control systems, medical equipment and instrumentation as they provide a reliable, low-cost custom interface.
Membrane Keyboards consist of printed fascia’s and flexible circuit layers sandwiched together to make a complete switch assembly. Manufacturing advances allow additional embedded components such as LED’s and RFI Shielding to be encapsulated within the keyboard structure.
Custom printed top layers and numerous key structure options ensure that membranes keypads can meet a designer’s ergonomic and aesthetic criteria, as well as satisfying more technical parameters such as robustness, Chemical Resistance, Ingress Protection and long operational life.
Compared to other switching technologies such as rubber keypads or Capacitive touch technology, membrane keyboards have the advantage of significantly lower cost tooling and simpler mechanical and electrical integration.
