Hand soldering
Automatic
soldering
Do not use soldering flux that contains chlorine. Doing so may
result in metal corrosion.
Perform hand soldering using the appropriate soldering iron.
With the exception of PCB-mounting Switches, when performing
hand soldering, hold the Switch so that the terminals point
downwards so that flux does not get inside the Switch.
Leave a gap of at least 1 mm between the soldered parts and the
surface of the case so that flux does not get inside the Switch.

Application
•
•
When applying flux using a brush, use a sponge soaked in flux as
shown below. Do not apply more than is necessary. Also, apply
the flux with the PCB inclined at an angle of less than 80° so that
flux does not flow onto the mounting surface of the Switch.
Do not place PCBs that have had flux applied or have been
soldered on top of each other. Otherwise, the flux on the PCB’s
solder surface may stain the upper part of the Switch or even
permeate the inside of the Switch and cause contact failure.
