| Graphic images are created
by screen printing colored inks on the subsurface side of
clear substrate material. Once printed and cut to size, this
layer becomes the Graphic Overlay.
The graphic overlay is an integral part of the membrane switch.
It is the most visible portion of the switch assembly, displaying
colors, graphic pattern as well as switch locations for operation.
It also provides protection for an environmentally hostile
application.
Only ones imagination and budget limit the range of decorative
options. ( For prototypes computer printed Graphic
Overlays is best suited option.)
We recommend a graphic layer material based on their experience
and a careful review of the application details. While majority
go for Polycarbonate material polyester is becoming popular
material for applications that demand CLEAR DISPLAY / Embossing
of the keys etc. |
