MEMBRANE SWITCHES & DECALS
Keypads and Switches
Flat, self contained, adhesive keypads and switch banks
LGF (Light guide film) Backlit Membrane Keypads
Backlit membrane switches
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.
What material should I specify for decal and membrane switches?
See the post below for an explanation on the different physical properties of various Overlay material (front layer material) Membrane material design
Membrane switch overlays are typically polyester material. Polyester allows for the flexibility required for membrane switch operation without fracturing the overlay. Polycarbonate, is unsuited for membrane switches, but is perfectly fine for decals and labels where there is no movement required. For every material advantage, there will generally be an offset and the toughness of polyester limits the embossing height.
Polyester films are available with gloss or textured finishes in the film itself. While texturing and gloss finish areas can also be silk screened onto the base overlay polyester.
For outdoor applications, we recommend Autotex XE for its UV stability
