Precautions

  • Do not apply additional force to the plunger once it has stopped moving.
  • Solder at 260°±5°C within five seconds and within two tries.
  • Do not wash the switches. The switches may be damaged by solvents if either wiped off using solvents or immersed in solvents.
  • Do not allow flux or flux foam to penetrate onto the component side of the PCB.
  • Use a single-sided PCB with a thickness of 1.6 mm. The switches may be damaged due to instability or heat from soldering if other PCBs (other thickness or through holes) are used. If it is necessary to use another PCB, test the compatibility and processing in advance.
  • The switches are not sealed and should be protected with a resin sheet as shown below when used in dust-prone environments. Resin sheets Switch Keytop
