RGB LED Illuminated Pushbuttons

The KP Series of illuminated miniature pushbutton switches from NKK Switches (Scottsdale, AZ) provide design engineers options that complete front panels needing an innovative look and feel. The devices are available with built-in RGB LED illumination, allowing the full color spectrum to be utilized to create unlimited color combinations.

An additional illumination option is Super Bright red/green built-in LEDs which can be combined to produce amber. In both configurations, the switches’ design ensures that illumination is evenly diffused throughout. The series’ square caps have a clear lens with a white diffuser and are offered in flat, sculptured, or home key styles - in three common sizes of 17.4mm, 15mm, and 12mm. A rectangular switch cap shape can also be specified.

KP Series pushbuttons can be specified with tactile or non tactile with silent actuation or with tactile and audible feedback. In all arrangements, a unique actuation guide gives positive indication of circuit transfer. Engineers can choose between two stroke travel and actuation force combinations. The shorter stroke option has a total travel of 3.5mm, with a pretravel of 2.3mm, overtravel of 1.2mm, and an actuation force of 1.6N. The longer stroke option has a total travel of 4.5mm, with a pretravel of 3.1mm, an overtravel of 1.4mm, and an actuation force of 1.9N.

Rated at 100mA maximum @ 12V DC, the pushbuttons have twin contacts with gold plating to assure high reliability. Epoxy sealed terminals lock out flux, dust, and other contaminants.
