Precautions
Warning
Please do not perform wiring or touch the charged
parts of terminals while power is supplied to the
Switch, as electric shock may occur.
Caution
• Use the switch within the rated voltage and current ranges,
otherwise the switch may have reduced durability, radiate
heat, or burn out.
This particularly applies to the instantaneous voltages and
currents when switching.
●Environment for Storage and Use
• To prevent deterioration such as discoloration of the terminals
and other problems during storage, do not store/use the switch
in location subject to the following conditions.
1. High temperatures or humidity
2. Corrosive gases
3. Direct sunlight
4. Sea wind
Also, the switch is not waterproof or splash-resistant. Do not
install or use the switch in locations that are subject to contact
with water, oil or dust.
• Do not subject the switch to freezing conditions or
condensation.
Correct Use
●Mounting
• Pay attention to the creepage distance/clearance distance for
insulation after wiring onto terminal when mounting frame is
made of metal.
●Wiring
• Please use the receptacle that is compatible with 4.8×0.8 mm
quick connect terminal (#187) when using it as a quick connect
terminal.
• Ensure that the wires are thick enough for the load (current) to
be applied.
• The performance of the Switch may be affected if used under
micro loads. Please test the Switch under actual operating
conditions.
• It is possible to use the terminals as a soldering terminal.
However, it is not in compliance with safety standards for use
as solder connection.
Please use it as the quick connect terminal when standard
approval is necessary.
• When soldering terminals manually, perform soldering within 5
seconds using a 60 W soldering iron (temperature at the tip of
the soldering iron: 350°C max.). Do not apply excessive force
to the terminals during soldering.
• Applying the tip of the soldering iron to the root side of the
terminal can cause deformation of the Housing and Base.
• This product does not correspond to the flow solder and reflow
solder.
It causes the malfunction by the infiltration of flux and the
thermal deformation.
●Handling
• Avoid shock damage to the product when handling. Shock can
cause deformation or break of the product.
• Do not apply excessive operating force to the switch to avoid
deformation or damage.
• Apply an operating force not exceeding 30N {3,059 gf}.
Do not apply a load from an angle or from the side of the
actuator.
●RoHS Compliant
The "RoHS Compliant" designation indicates that the listed
models do not contain the six hazardous substances covered by
the RoHS Directive.
Reference:
The following standards are used to determine compliance for
the six substances.
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.
