flexibility to customize the blank inserts included
on the sheet of popular legend letters, words
and symbols provided or on the insertable
legends sheet.

PRINTED LEGENDS
For Maximum Versatility
Printing allows you the flexibility to create your
own legend using whole words and symbols
with various type styles. Durable epoxy ink
printing bonds to the button cap surface. There
are two types of button cap printing:
Top Surface Printing: Legend is applied directly
to the top of the button. Button is recessed
slightly below the keyboard housing.
Sub-Surface Printing: For insertable legend
models. Provides maximum wear for printed
surfaces. Printed internal button cap is protected
by clear snap-on cap.
Printed Typestyles: The typestyle chart
illustrates type style, size and approximate
character limits for button caps. Grayhill's library
of typefaces includes most popular legends.

Special Legends
Follow this procedure:
1. Basic Keyboard. Formulate the part number
with the exception of the legend suffix.
2. Mounting. Standard mounting is shown in
our dimensional drawings. These drawings
relate the terminal location to the button
legend orientation. It is possible to rotate the
button legends by 90°, changing the
orientation. When mounting the keypad, it
would be rotated 90° to have the legends
appear upright. A 3x4 keypad thus becomes
a 4x3.
3. Color. Many colors, other than our standard
black housing, are available. Buttons can be
made from equivalent plastic in black, red,
green, blue and yellow. White legends are
used with dark color buttons, black with light
ones. Other colors available on special order.
4. Buttons. Legends can be printed on button
surface and protected by a snap-on cap in a
similar fashion to our insertable legend types.
A second option is printing a ‘blank’ button.
(One that has the same dimensions as a
molded-in legend button with a flat top
surface.) Disadvantage is legend wear over
time. A third option is molded-in legends,
usually requiring tooling. Molded buttons are
available with a flat or concave top surface.
5. Legends. Specify the legend requirements
for each button. Identify buttons per our
dimensional drawings. Caution if keypad has
been rotated.
