摘　　要：家用和类似用途的固定式开关,以规格10 A 250 V为例,在完成40 000次的正常操作试验后,在对开关处于"通"位置时电气上连接在一起的端子之间进行电气强度试验时(这时开关要处于"断"位置)击穿现象屡见不鲜。本文分析了问题产生的原因,并提出解决问题的建议。Fixed switches for household and similar electrical installations, taking the standard of 10 A 250 V as an example, after 40 000 normal operation, breakdown occured frequently between the terminals when conducting the electric strength tests, which was electrically connected together. This article analyses the causes and gives some suggestions to solve the problem.
