hi folks

i'm happy to know that it's at least possible to do

Radio Shack has become CircuitCity around here, and they don't carry much of electronics anymore...
I will probably make an order at Digikey.

I'm looking to drive two 12v (DC) HelmetCam, who drink 130mAh approx. each.
(but it runs very hot... I wonder how it can only be taking 130...)
At first I wanted to have some kind of soft power switching, because that whole thing is plugged into a camcorder, but this sounds very complex to me so I will use Zener diode in the circuit to prevent overvoltage peak.
KIS system

I need Latching because I won't be switching too often, and the circuit can run for more 6-7hours non-stop.

thanks all!
