Don't worry about that any more Expertune.For "insider",this is a typical applicaton.Just ask an electrician,he/she should be able to tell you.

I do not think you have discribed the question properly. And "两个开关,一个只能把灯打开,另一个只能把灯关上" is mission impossible. :-) I wanna know who asked you to do this? What's the context?

Part list:
NC momentary switch 1pc about $1.3
NO momentary switch 1pc about $1.3
relay-----voltage=power source voltage 1pc about $5.00
wire 22 AWG 8 feet or whatever about $0.80
Parts price from Radio Shack may be a little bit higher.
Time to go,see you tomorrow.Hope case closed.Thanks EXpertune.
This is very common question and in fact you made all the thing so tough. I don't want to explain it by a long article. As the people said your problem is mission impossible.
