Precautions
■ Precautions for Correct Use
Storage
Storage Environment
To prevent degradation, such as discoloration of the terminals during
storage, do not store the Switch in locations that are subject to the
following conditions;
• High temperature or humidity
• Corrosive gases
• Direct sunlight
• Using the Switch in an underwater setting where it is subject to strong water pressure.
Storage condition
Store the Switches in the packaging box.
After the packaging box is opened, use the contents as quickly as
possible. When storing leftover parts, make sure that appropriate
measures are taken against humidity and corrosive gases.
Handling
Usage Environment
Before installing the Switch, make sure that the area of installation is
not subject to corrosive gases emitted from surrounding parts.
1. Do not use in areas subject to high temperatures, high humidity, or toxic gases such as sulfuric gas (H2S, SO2), ammonia
gas (NH3), nitric gas (HNO3), or chlorine gas (CI2). It can
cause corrosive damage to the contacts and result in malfunction.
252
Middle Stroke Tactile Switch
2. If there is silicon in the atmosphere, it may stop the contacts
from functioning properly. If silicon products, such as silicon
oil, silicon filler, or silicon wires, are used in the surrounding
area, install a contact protection circuit to prevent arching or
remove the silicon source. The Switch is not completely
sealed. The following situations may cause water to enter
inside the Switch, resulting in a malfunction due to contact
failure or corrosion.
• Using the Switch in an outdoor environment where it is
exposed to water drops for an extended period of time
B3SL
Operation
• Do not repeatedly operate the Switch with excessive force.
Applying excessive pressure or applying additional force after the
plunger has stopped may deform the disk spring of the Switch,
resulting in malfunction. (Maximum force = 30N)
• Be sure to set up the Switch so that the plunger will operate in a
straight vertical line. If the plunger is pressed off-center or from an
angle it may cause deformation or damage to some parts. This may
result in deterioration of life expectancy or malfunction.
Electrical Operation
RoHS Compliant
Use the Switch within the rated voltage and current ranges, otherwise the Switch may have a shortened life expectancy, radiate heat,
or burn out. This particularly applies to the instantaneous voltages
and currents when switching.
The "RoHS Compliant" designation indicates that the listed models
do not contain the six hazardous substances covered by the RoHS
Directive.
Soldering
Reference:
The following standards are used to determine compliance for the six
substances.
Soldering Precautions
1. Before any kind of soldering, test to confirm that soldering can
be performed properly. Otherwise the Switch may be
deformed by the soldering heat depending on the type of
PCB, pattern, or lands of the PCB.
2. Do not solder the Switch more than twice, including rectification soldering. Wait for at least five minutes between the first
and second soldering to allow the temperature to return to
normal. Continuous soldering may cause the casing to melt or
deteriorate the Switch characteristics.
Reflow Soldering Conditions
Firmly attach a thermocouple to the surface of the terminals with solder that has a high melting point and set the reflow oven so that the
peak temperature of the terminals is 260°C or less.
The following figure shows the temperature profile.
Lead:
1,000 ppm max.
Mercury:
1,000 ppm max.
Cadmium:
100 ppm max.
Hexavalent chromium:
1,000 ppm max.
PBB:
1,000 ppm max.
PBDE:
1,000 ppm max.

2. Soldering time: 3 s max. for a 1.6-mm thick, single-side PCB
Washing
Standard Switches are not sealed, and cannot be washed.
Doing so will cause the washing agent, together with flux or dust
particles on the PCB, to enter the Switch, resulting in malfunction.

Common Precautions
Be sure to read the precautions common to all Tactile Switches, contained in the Technical User’s Guide, “Tactile Switches, Technical
Information” for correct use.
Using PCBs with a different thickness or using double-sided,
through-hole PCBs may result in loose mounting, improper insertion,
or poor heat resistance in soldering. These effects will occur,
depending on the type of holes and patterns of the PCB. Therefore, it
is recommended that a verification test is conducted before use.
