Miniature Audio/Video Pushbuttons
Series KP
Distinctive Characteristics
KP series offers a complete switch solution for all broadcast panel needs,
including home keys and the custom 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 red/green bicolor LED and custom RGB LEDs.
The RGB LED full color spectrum in a switch package provides
unlimited color combinations.
Specially designed snap-in standoff for simple and
secure PC board mounting and alignment.
Unique actuation guide gives positive indication
of circuit transfer as well as smooth and silent
operation. (Patent pending).
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
IS series programmable SmartSwitch™.)
Flat, sculptured or home key square caps in three
common sizes for design flexibility in audio/video
applications.
Twin contacts with gold plating assure high reliability
and long life of 5,000,000 operations minimum.
Epoxy sealed terminals to lock out flux, dust, and other
contaminants, plus standard PCB spacing of .100” (2.54mm).

Standards & Certifications
UL Recognition
or CSA Certification:
The KP Series pushbuttons have not been tested for UL recognition or CSA certification.
These switches are designed for use in a low-voltage, low-current, logic-level circuit.
When used as intended in a logic-level circuit, the results do not produce hazardous energy.

Minimum Luminous Intensity
LEDs are an integral part of
the switch and are not avail-
able separately.
LED circuit is isolated and
requires an external power
source.
If the source voltage exceeds
the rated voltage, a ballast
resistor is required.
The resistor value can be
calculated by using the
formula in the Supplement
section.
