Soldering Instructions
Series 82 Keyboard Modules have been
successfully tested for heat resistance to
soldering up to 260°C (500°F) for a maximum of
5 seconds. Careful flux cleaning is required
since the switch is not sealed. For applications
in excess of these limits or that require vapor
spray or immersion cleaning, contact Grayhill.
Telephone Keyset
Two 6-button modules
form the keyset. White
telephone legend is
molded into a gray
button. SPST, 2PST,
3PST, and 4PST

SPECIAL LEGENDS
Molded-In Legends
For Unlighted Modules
In addition to standard white
legend on gray button, long-
wearing, molded-in legends are
available in white button with black
legend and white legend with red,
green or black buttons. Other
color combinations are possible.
Printed Legends (2 Styles)
Virtually anything which can be photographed
can be printed. Sturdy epoxy ink printing bonds
to the surface of the button. Standard printing
for the gray unlighted buttons is white; standard
printing for the translucent white buttons of the
lightable modules is black.
Top Surface Printing: Legend is applied directly
to top of button. Available on all standard,
unlighted modules.
Sub Surface Printing: Provides maximum wear
for printed surfaces. Available for lighted and
unlighted gray modules. Printed internal button
cap is protected by a clear outer cap.
Printed Type styles
The type style chart below illustrates type style
and approximate sizes and limits for button cap
legends; other sizes are also available. Limitations
for legends differ with type size and character.
Legends for lightable modules are further limited
by the size of the internal button and lighted area.
Grayhill's library includes many popular legends.
