Amp Rating of Switches

Kind of a noob question..

So I've been looking to buy some new switches for my truck (for lights, etc)
Each switch has similar ratings, for example;
6A 250V - 10A 125V
8A 250V - 12A 125V

Since cars are 12v, what would the Amp rating be?

It kind of depends on how your running your circuit as to determine what amps rating you need. I just hit the same snag, but am running all my accessories through separate 30 amp relays so my switches only need to be 10 amp rated or so, the load is being carried by the relay, switch just turns relay on. If you do not use a relay, then you will need to find switches that are higher amperage to be able to carry the load of your accessories.
Switches I bought all had a listed DC rating, not sure how that translate into AC ratings you are listing.

Yes, I am using a relay for all applications.
I just want to make sure nothing burns to the ground.
