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.
