LGF (Light guide film) Backlit Membrane Keypads
The light guide film (LGF) brings integrated LED backlighting to membrane switches and front panel decals allowing text and full key illumination. Our LGF provides even light distribution across the keypad/decal front panel while keeping the thickness similar to standard membrane switch panels.
Duraswitch products offer a durable and reliable alternative to the traditional membrane switch. Their thin profile design works without scraping, flexing, grinding or material compromise associated with traditional switches.

What material should I specify for decal and membrane switches?
See this post for an explanation on the different physical properties of various Overlay material (front layer material) Membrane material design
There are two basic types of circuit layers that are used in membrane switch assemblies, PET and FPC. PET is a polyester where the circuit is silver ink and applied to the base material in a screen printing process
FPC or flexible printed circuit
Is a polyimide (Kaptron) base with a copper etch for the circuit, similar to traditional PCB manufacture but in a much thinner format and allows for soldering of components and connectors.
