When using our Light Touch Switches, please ob serve
the following items (“prohibited items”) and be
cau tious of the following in order to prevent dan ger ous
accidents and deterioration of performance.
1. Notes on soldering conditions
When performing solder dipping, check the soldering
conditions according to the “Product Specifi cation
for Information,” because the conditions vary with the
prod uct. Do not wash the switch after solder dipping
be cause fl ux may enter the switch, resulting in contact
failure. Avoid use of jumper cables near the switches
be cause fl ux may attach to them.
1. Control the liquid level so that fl ux does not enter
2. When performing manual soldering, perform it at a

When performing refl ow soldering using a hot-air
oven or an infrared oven, observe the following
con di tions. Since the temperature applied to a
switch and its ter mi nals varies with the type and
size of the PWB and the mounting density of the
parts, suf fi cient ly check the conditions in advance.

3. Other prohibited items and notes
1. Take care not to apply excessive load to a switch.
2. Suffi ciently check any generation of corrosive gas
3. To prevent contact failure due to foreign matter
4. Prohibited items and notes on storage con di tions
Do not store the switches under high temperatures
and/or high humidity, or in a location where cor ro sive
gas may be generated. Store the switches at room
tem per a ture and room humidity in a packed con di tion.
Use them within a maximum of 6 months af ter de liv ery.
Check the date of manufacture on the pack age box
and ap ply the “fi rst-in -fi rst- out” rule. If unpacked
switch es must be stored as inventory, store them in a
poly eth yl ene bag to keep out air.

If misuse or abnormal use may result in conditions
in which the switch is used out of its rated range,
take proper measures such as current interruption
