日前,一位朋友告诉笔者,他母亲在一天晚上关日光灯时,被拉线麻了一下,吓得她至今不敢开这盏日光灯。按理,在诸多开关中,由于拉线开关在开、关时不与人直接接触,在使用过程中相对而言最为安全。带着种种疑惑,我来到现场一看,发现拉线开关的拉线不是常用的绝缘线,而是一根破旧不堪的绿色软芯电线,打开开关盖,拉线打结一端的铜丝正好碰到带电桩头,另一端铜丝也早已外露,难怪要麻手。 Recently, a friend told the author that when his mother turned off the fluorescent light one night, she was pulled up and she was scared to open the fluorescent lamp until now. Logically, in many switches, pull the switch in the opening and closing when not in direct contact with people in the use of the relative process is the most secure. With all sorts of doubts, I came to the scene and found that the cable pull cable is not commonly used insulated wire, but a dilapidated green soft-core wire, open the switch cover, pull the end of the wire just hit the wire Pile head, the other end of the copper wire has long been exposed, no wonder want to Ma hand.
