谁家都想让自家的灯泡寿命长,最好一只灯泡用个十年八年才好。新灯泡点上三五天,三两个月就得换,费钱不说,换泡登高,有时还有触电危险;公共场所、楼道照明一般用灯时间长,经常换灯泡也很烦人。目前还有一种新式楼道灯,晚上人来灯亮,人走灯灭,用这种开关的灯更容易坏,换灯泡更频繁。对我们的铁路来说,指挥行车的信号灯要经常变换颜色,换灯泡更是个苦差事,尤其是北方的冬天和南方炎热的夏天,要登梯子爬高不说,更换不及时还要影响行车,造成事故就要受处分,更是责任重大。于是有的电务段采用了神奇钮。情况大大好转了！ Everyone wants their own long lamp life, it is best to use a bulb for ten years and eight years. New light bulb on the three five days, three or two months have to change, money does not say, change the bubble ascending, and sometimes there is the danger of electric shock; public places, corridor lighting general use of light for a long time, often changing bulbs are also very annoying. There is also a new type of corridor lights, people come to light at night, people go out the lights, with the switch of the lamp is more likely to be bad, change the light bulb more frequently.

So some of the electricity section using the magic button. The situation is much better!
