C&K Components has designed the K12S Series of robust, IP67-sealed SMT key switches for harsh environment applications. By employing an advanced material that provides better transparency while withstanding high reflow temperatures, C&K has enhanced the luminosity of the K12S Series switches, with a choice of six standard LED colors to accommodate specific customer application requirements.

  • Available with LED illumination or double action and detect versions
  • DPST, dual-contact versions available with a double-step actuation of 6/12N
  • Features tactile feedback and reliability
  • Low contact resistance (<100 mOhms)
  • 100N overload resistance
  • Achieves 1,000,000 life cycles on specific versions
  • RoHS compliant and halogen-free
  • Offers flexibility to tailor force values, actuation travel options and provide single pole double throw (SPDT) custom solutions to meet application requirements
  • Includes actuation force range of 1.5N to 9N with an overload of 100N and total travel of 1.5mm
  • Double-action design provides sharp tactile feedback on both actions
  • Features maximum power rating of 3 WDC and a voltage of 2V to 30V DC with a current rating of 10uA to 100mA
  • Operating temperature ranges from -40 C to 85 C
  • Available in an IP40-rated package for less demanding applications
  • Low PCB-mounted profile makes them ideal for mechatronics design engineers to integrate into complex sub-assemblies requiring precise control for joysticks, remote controls, vehicle cabins and forklift/crane controls
