NOTES
1. Soldering operations
1) For manual soldering;
By using 18W Max. (iron tip temperature:
320°C 608°F Max.) soldering should be
completed within 3 seconds.
2) For reflow soldering;
Perform soldering reflow at a peak surface temperature of the PC board not to
exceed 245°C 473°F. See the below rec-
ommended temperature profile.

3) During soldering, care should be taken
not to apply excessive stress to the terminals as the resulting deformation may
cause malfunction. Excessively high solder tab temperature and soldering iron
wattage should also be avoided as these
factors may harm switching performance.
2. Setting of the operation object
In setting the operation object; keep the
following distance between the switch bottom and the operation object at T.T.P. (Total Travel Position)

3. Quality Check under Actual Loading
Conditions
To assure reliability, check the switch under actual loading conditions. Avoid any
situation that may adversely affect switching performance.
4. Environment
1) These switches do not have a sealed
construction. As such, the construction of
the equipment in which the switches are
to be installed should be given careful
consideration when the switches are to be
used in locations where corrosive gases,
silicon or other substances which will adversely affect the contacts are used,
where there is a high concentration of
dust or where the switches may be exposed to condensation or water. Using
switches in locations like these may cause
malfunctioning.
2) Avoid using this switch in high-temperature, high-humidity or condensationforming environments and avoid allowing
droplets of water to remain on the switch
or come into contact with it. These conditions may interfere with the performance
of the switch (resulting in short-circuiting,

migration, etc.). Use the type with the gold
contacts in applications involving trains,
aircraft, motor vehicles or medical equipment where the switch must satisfy safety
and high reliability requirements. Please
consult with us for the applications required high reliability.
3) Because the humidity range differs depending on the ambient temperature, the
humidity range indicated below should be
used. Continuous operation of the switch
is possible within this range, but continuous use near the limit of the range should
be avoided.
• This humidity range does not guarantee
permanent performance.
(Avoid freezing when
used at temperatures
lower than 0°C 32°F)
