I have few questions here. Hope you have the answer for it.

1: Is this your new home? (Call the builder if answer YES)
2: Is this a house you just move in? (Make sure it is something wrong before makes any wiring change)
3: Was any wiring change by someone or yourself? (Do you remember what has change?)
4: These wiring will not change on its own, try to remember what you have done recently.
5: The light that controlled by the 1st switch. is it also controlled by a 2 second switch?(one light can on/off at two different location?(most of the house, the light for the hall way is controlled by two 2 way switch, it is convenience turn light on when you come home. and light can be turn off after walk in the middle of the house.

Base on what you said. There are two possibilities
#1 : The Red and the Black wire are two different phase that come out from the main panel, black used for the light, and the Red just pass though the junction box then feed to other light switche or out let.

#2: The Red is a back feed to or from the second 2 way switch. (One light can switch on/off from two locations.)

By the way. My home have a switch at the door entrance, works exactly the same as yours. One switch turns on/off my living room outlet. And one light as well.更多精彩文章及讨论,请光临枫下论坛 rolia.net

    我家的房子的照明系统有些毛病.
    现象: 进门时先进厨房,厨房的第一个灯的开关本应该独立, 可实际情况是它串联到电路中成为后级若干灯和插座的开关了. 只有把此灯打开,后级的各个灯才可以由各自的开关控制. 如果关上后面的灯全部不亮,
    我检查了这第一个等的开关, 里面有5根线,2根白的用短路套套着,没接到开关上, 剩下是两根黑的,一根红的. 其中一根黑线应该是从电源过来的.是常带电的.另外一根黑线就是接到第一个电灯和后面各级的.还有一根红线没有任何作用. 用个2线开关把2根黑线分别接到开关两极就出现上面描述的现象,
    我现在不知道红线在这里是什么作用,而且要是把串联改并联,也没法办到, 是不是第一个电灯的灯座里可以改呢? 为了验证,我打开了灯座,里面黑线接了三根黑线, 白的接了白线. 我怀疑可以在三根黑线里做做文章, 可又觉得不太应该这么接的, 各位,谁给点注意呢?
    • 电工们呢?
      • call me at 416-275-9310,i tell you how to fix it
    • do you have Multi meter and know how to use it?do not touch it, it is not DIY.project I know the code so I can buy my electric permit and do it myself and pass inspection, your case is not just a code, it is correct the wrong wiring.
      • 需要重新做这几盏灯的连接。原来的人将这几盏灯接错了。
      • 明显把三相开关中的红线当火线用了。
