anyone else? please i want multiple opinions.
Also your SWITCH. is it just that? just an on off switch?
If you use a relay with the ignition, you can ensure that you never forget to turn the switch off and come back to a flat battery.
I've got a relay that controls a fuse box in the trunk wired directly to the battery (with a fuse as close to the battery as possible). From the fuse box, I power a Kensington 120W laptop adapter (which was spliced into to get a 5V line for my external soundcard), another 5V power adapter for my USB hub (from a 2W USB cigarette lighter power source), my amp for the front and rear speakers, and my subwoofer.
Otherwise, it looks good
the usb hub will be powered through the usb line... not sure if that makes it powered or not.
The switch is just that, an on off because i only want this for longer than 5 minute trips... so i see no reason to install a relay and a valet switch when i can just use the switch.
the point of the relay (as thefdog mentioned) is to ensure that power [to your pc, monitor, cig lighter, etc] is cut when car is off. you can still use a switch with a relay to only apply power when you want it. the relay simply ensures that you'll never have a dead battery because you forgot to switch power off to all your devices.
your plain old on/off switch will work fine (as long as it can handle the current that all those devices will pull from it), but you'll have to remember to switch it off when you leave the car. otherwise it may drain your battery. with a relay you'll never have to worry about that.
from this thread and several others you started (they are basically all about the same topic) you seem very reluctant to add a relay to your setup and I'm not really sure why. it will only make your life easier. they only cost $5 and it's only 2 extra wires
As a low voltage electrician i agree totally. Use a relay. This way there is no OOPS factor. Will also help prolong the life of you battery from excessive deep discharges of you battery.......when you forget to turn off the switch.......that's my 2 cents.
