Create gap
When performing soldering with a dip soldering bath, ensure that
the flux does not reach a higher level than the PCB.
Flux is especially likely to rise up at the edges of the PCB. If the
Switch is mounted near the edge of the PCB, create a gap
between the edge by using a split PCB, and insert the PCB in the
soldering bath so that the edge that is farthest from the Switch
enters the bath first.
When the Switch is left unused or stored for long periods, the
ambient conditions can have a great effect on the condition of the
Switch. In certain environments, leaving the Switch exposed
may result in deterioration (i.e., oxidation, or the creation of an
oxide film) of the contacts and terminals, causing the contact
resistance to increase, and making it difficult to solder the lead
wires. Therefore, store in a well-ventilated room, inside, for
example, a non-hygroscopic case, in a location where no
corrosive gases are present.
If the Switch is stored in a location where it will be exposed to
direct light, colored resin in the colored plate may fade.
Therefore, do not store the Switch in locations where it will be
exposed to direct light.
