Satisfying this test condition does notmean that the Switch can be used underwater.JIS C0920:Degrees of protection provided by enclosures of electricalapparatus (IP Code)IEC 60529:Degrees of protection provided by enclosures (IP Code)Degree of protection: IP67(check water intrusion after immersionfor 30 min. submerged 1m underwater)• Do not operate the Switch when it is exposed to water spray,or when water drops adhere to the Switch surface, or duringsudden temperature changes, otherwise water may intrudeinto the interior of the Switch due to a suction effect.• Prevent the Switch from coming into contact with oil andchemicals.Otherwise, damage to or deterioration of Switch materials mayresult.• Do not use the Switch in areas where it is exposed to siliconadhesives, oil, or grease.
