I'm looking for switched power (turns off when you turn the key off) for my cigarette lighter bluetooth adapter. I'd rather not jump the fuses as some have done.

There's a BMW Auxiliary Power Adapter that plugs in where the flashlight goes, and it provides another socket. They used to be $10, but now that they are no longer available, they sell for $150-200. So I made my own similar to this: http://www.m5board.com/vbulletin/e39...l-adapter.html

The only problem is, what I understood was switched power is not. This defeats the purpose of me making my own adapter.

Is it supposed to be switched?

Thanks,

Paul
