Operating Environment
•
The Switch does not have a water-resistant structure. Take
measures to protect the Switch if it is to be used in locations subject
to splashing or spraying water or other liquids.
•
Do not use the Switch where it is continuously subjected to vibration
or shock. Doing so will result in contact failure, malfunction, or a
decrease in service life caused by abrasive powder that is
generated from the internal parts. Subjecting the Switch to
excessive vibration or shock may cause the contacts to
malfunction, stick, or become damaged. Make sure to install the
Switch in locations free of vibration or shock or in a direction where
resonance will not occur.
•
Do not use the Switch in locations subject to corrosive gas, such as
sulfuric gas (H
2
S or SO
2
), ammonium gas (NH
3
), nitric gas (HNO
3
),
or chlorine gas (Cl
2
), or high temperature and humidity.
Doing so will result in damage due to contact failure or corrosion.
•
If the Switch is used in locations with silicone gas, arc energy may
cause silicon dioxide (SiO
2
) to build up on the contacts and contact
failure may result. If there is silicone oil, silicone sealant, or wire
covered with silicone close to the Switch, attach a contact
protective circuit to suppress the arcing of the Switch or eliminate
the source of silicone gas.
•
Use the switch within the specified range for operating temperature
and humidity. Using the Switch in high temperatures will cause the
operating characteristics to deviate. Rapid changes in temperature
will also cause the operating characteristics to deviate. It is
recommended to install the Switch as far as possible from heat
sources so that the temperature of the Switch is not affected.
