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 SmartDisplay). 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.
