Light Touch Switches
■
5. Prohibited items on fire and smoking
Application Notes
When using our Light Touch Switches, please observe
the following items (“prohibited items”) and be
cautious of the following in order to prevent dangerous
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
product. Do not wash the switch after solder dipping
because flux may enter the switch, resulting in contact
failure. Avoid use of jumper cables near the switches
because flux may attach to them.
1. Control the liquid level so that flux does not enter
the switch from the top.
2. When performing manual soldering, perform it at a
temperature of 350 °C within 3 seconds.
3. Do not apply a load to the switch lever after soldering.
4. For reflow soldering
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 terminals varies with the type and
size of the PWB and the mounting density of the
parts, suf ficiently check the conditions in advance.
5. When a board with double-sided through holes is
used, do not make through holes immediately under
the switch case. Otherwise, the switch case may fuse.
2. Notes on design of a set
1. For switch mounting holes, refer to the “Recommended
PWB piercing plan” as described in “Dimensions.”
2. For shapes of operating parts in a set, refer to
rec om mend ed shapes described in “ Product
Specifications for Information.”
1. Absolutely avoid use of a switch beyond its rated
range because doing so may cause a fire.
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
using a protective circuit.
2. The grade of nonflammability for resin used in Light
Touch Switches is “94HB”, which is based on UL94
Standards (fl ammability test for plastic materials).
Prohibit use in a location where a spreading fi re
may be generated or prepare against a spreading
fire.
6. For use in equipment for which safety requested
Although care is taken to ensure switch quality,
variation of contact resistance (increase), short
circuits, open circuits, and temperature rise are
some problems that might be generated.
To design a set which places maximum emphasis
on safety, review the affect of any single fault of
a switch in advance and perform virtually fail-safe
design to ensure maximum safety by:
1. preparing a protective circuit or a protective
device to improve system safety, and
2. preparing a redundant circuit to improve system
safety so that the single fault of a switch does
not cause a dangerous situation.
7. For actual use, be sure to refer to “Product
Specifications for Information.”
3. Other prohibited items and notes
1. Take care not to apply excessive load to a switch.
Doing so may cause terminal deformation, contact
failure, and/or malfunction.
2. Sufficiently check any generation of corrosive gas
from the components in a set under actual operating
conditions. Corrosive gas may cause contact failure
and corrosive stress cracking of metal.
3. To prevent contact failure due to foreign matter
(such as chips of a PWB and fl ux) entering a
switch, take care when handling a PWB after mounting.
Do not stack the PWB’s.
4. Prohibited items and notes on storage conditions
Do not store the switches under high temperatures
and/or high humidity, or in a location where corrosive
gas may be generated. Store the switches at room
temperature and room humidity in a packed condition.
Use them within a maximum of 6 months after delivery.
Check the date of manufacture on the package box
and ap ply the “fi rst-in -fi rst- out” rule. If unpacked
switches must be stored as inventory, store them in a
polyethylene bag to keep out air.
Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use.
Should a safety concern arise regarding this product, please be sure to contact us immediately.
