Appearance
The KP01 and KP02 Series illuminated pushbutton switches will
have changes to the LEDs. This change will affect the illumination
of all KP models, both standard and custom. All of the bicolor KP
models will have brighter, more vibrant illumination. Differences
in the LED specification values are outlined on the table below.

Notes
The electrical specifications shown are determined at a basic temperature of 25°C.
LEDs are an integral part of the switch and are not available separately.
The LED circuit is isolated and requires an external power source.
If the source voltage exceeds the rated voltage, a ballast resistor is required.
The external resistor value will change with the new LED specifications.
The changes to KP LED does not affect any external dimensions of the switches.
For any further details, contact our sales department. Availability
Change to KP Series bicolor LEDs will be effective with August 2010 production.
