Temperature and humidity
To ensure the long-term stability working of the switch , please
maintain a certain temperature and humidity environment.
High or low humidity easily lead to leakage of insulation
materials, deformation and even the corrosion of metal parts,
the temperature is too high will accelerate the aging process
of insulating materials, seriously affecting the service life of
equipment. The normal operation of this series of switches
and storage temperature / humidity are as follows
