Distinctive Characteristics
KP series offers a complete switch solution for all control panel needs,
including home keys and the rectangular switch/cap assembly.
Distinct, long total travel of .177 (4.5mm) for KP01 or shorter stroke
of .138 (3.5mm) for KP02.
Available with super bright amber/blue bicolor LED or
D
super bright RGB LED. The RGB LED provides vibrant
full color spectrum in unlimited color combinations,
and is offered in both 4-pin or 8-pin terminations.
Unique actuation guide gives positive indication
of circuit transfer as well as smooth and silent
operation.
Choices of tactile, nontactile or tactile/audible
actuation.
Compact design with height of .906 (23.0mm)
from PC board to top of cap (same height as
programmable SmartSwitch .)
Flat, sculptured or home key square caps in three
common sizes for design flexibility in various
applications.
Twin contacts with gold plating assure high reliability
and long life of 5,000,000 operations minimum.
Improved profile for soldering specifications (RGBP models).
Standard and custom alternating legends available.
