Applications

Series KP04Compact Illuminated SMT Pushbuttons www.nkkswitches.com Distinctive Characteristics Actual Size One of the most preferred series of illuminated pushbuttons in the industry now features surface mount technology. Surface mount technology facilitates diminished board and material handling expenses, in addition to minimized routing of traces and fewer drilled holes. RGBP LED dispenses vibrant full color spectrum in unlimited color combinations. The RGBW with white option aids in reducing variations of the color tones for white illumination, administering stable and consistent color. Distinct, total travel of .138” (3.5mm). Switch actuation is synchronized with contact timing, delivering color without delay simultaneous to actuating the device. Switching ON signals safe, reliable and intuitive operation. Choice of 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 diverse applications. Twin contacts with gold plating assure high reliability and long life of 3,000,000 operations minimum. Custom legends available. Remarkably precise coplanarity: all considered surfaces lying between two parallel planes are a maximum distance apart of .0039” (0.1mm). (0.10) .0039Coplanarity

Also, an appropriately valued ballast resistor should be used. Without the ballast resistor, the LED will be damaged or destroyed.

  • Reflow soldering cannot be executed with the cap attached.
  • The Reflow Solder Profile describes the printed circuit board (PCB) surface temperature. Since the PCB surface tempera- ture and the switch surface temperature will vary depend- ing on the height of the switch, the PCB material, and PCB thickness, ensure that the switch surface temperature does not exceed 250°C for high temperature.
  • Verify soldering conditions prior to beginning the process.
  • The number of soldering procedures should not exceed two, including resoldering work, such as manual soldering.
  • After soldering, ensure no mechanical stress is applied to the terminals due to bending or warping of the PC board.
  • Profiles are for lead-free components.
  • Use an alcohol based solution for flux cleaning on the PC board surface after soldering. Series KP04 switches are not process sealed. Home Key Caps When using the 12mm, 15mm or 17.4mm home key caps, do not apply pressure with a hard object to the projected dot on top of the caps. It may damage or deform the cap. Simultaneous Illumination Simultaneous illumination may cause color variability due to characteristics of the LEDs. Check and adjust the current value for each color that is used. If simultaneous illumination is required with a Red/Green/Blue/White (RGBW) LED, consult with our Engineering Department. Attaching the Cap to the Switch Caps are not assembled to the switch until after the reflow solder- ing process. If reflow soldering is executed with the cap attached, LED lighting failure, damage or malfunction may occur. Remove the heat resistant film from the switch before attaching the cap. The cap assembly is designed with projections that align with grooves on top of the switch. Confirm the recessed side of the upper plunger in the cap assembly is oriented with the recessed side of the lower plunger on top of switch and snap together. Press cap several times, checking for smooth actuation. Operating the switch without an actuator or with actuator improp- erly mounted may cause a malfunction or impairment. Legends for Top of Caps Surfaces of the caps are ideal for legends, and recommended methods include laser etch, screen print or pad print. Before using a film insert in the actuator, contact NKK Switches. The diffuser cannot be removed. ATTENTION ELECTROSTATIC SENSITIVE DEVICES Handling Series KP04 devices are electrostatic sensitive. To avoid damage to the switches, do not touch terminals unless properly isolated from static electricity. Applying a reverse voltage to the LED may cause leakage current or deterioration. Depending on circuit condition, a circuit protector may be necessary.
