Martin, 如果插头不是非极性插头,那么在此规则适用的情况下,开关必须是双极开关,这个是首要条件,必须符合。 8 U }; d/ Y& A3 f& k0 b- ] " f, R3 k* X3 ]7 u0 y " P8 { {$ t7 G: [: W而如果带了极性插头(保证用户端适用时插头对插座的L/N线匹配正确了),才允许适用单极开关,然后通过线材标示、印记等区别,保证生产时配线链接的正确。 7 | n: Z7 f+ I/ F/ ]8 p& D; u7 Z! X2 [( U( e' ^

所以个人觉得,非极性插头的话不允许这样做。作者: jsspace 时间: 2017-2-21 12:21
对于单极开关,要保证用在火线上,言下之意如果你保证不了,那就用全极断开吧作者: martin_cheng 时间: 2017-2-21 13:57
