After arguing with the foreman, he came to my house, and then the spotlights in my living room were

Your imagination is too rich, first of all, the foreman is also a person, nothing more than his experience and technology are richer than ordinary people, but he is not a god, he can't remotely control your downlight to stop working without moving your circuit, this should be a coincidence.

Don't talk nonsense, let's talk about the solution to the problem, a circle of downlights are all not lit, first of all, we must find the first downlight part of the switch to (according to experience, it should be the downlight closest to the off) to see if the control line is disconnected, if the judgment is correct, it should be the control line of the first light is disconnected (the control line should be a white line).

I don't think it could have been done by the foreman! Most of the switch is not in the right position, some need to switch twice to turn on (in fact, it is not the switch twice, but the feature of opening once), you can switch a few more times to try it. Some lights, the first time it is turned on is strong light, the second time is low light, and so on.

It's just that it's different every time, and you need to try the rules yourself. There's no way a foreman would do such a lowly thing!

This can't be done by the foreman! Let's try changing the lights first.
