The graphic overlay indicates the location of the keys and is the
esthetic component of the
keypad or device. MBR selects the best inks and most appropriate
materials to manufacture
them. Graphic overlays, which are particularly necessary for
membrane switches, are also
useful for instruments with mechanical keys, product
identification, labels, and dashboards.
The image is silk screened and placed behind a transparent surface,
ensuring permanent
identification.
