求教开关问题
我们家有几个房间的插座突然失电，当时用电量较大，检查发现控制小开关跳掉了，但手合开关，开关复不了位，小开关上有一个黄色的按扭，按了以后还是复不了位，是不是操作上有问题，请能人指教。 把所有电器都拔下来先，然后推上闸。也许有短路点。 To reset the breaker in the panel:The tripped breaker normally will be at the middle position between "on" and "off". One has to push the breaker to the end of "off" position first , then pull back to "on" position. Otherwise is hard just to pull the breaker to " On" position as regular on/off the breaker. 谢谢楼上两们关心指教。开关已投上。
