Switching power

Here is a diagram of the neon setup I have in my truck:

I don't know how to attach files on here so there's the URL

I've hooked up the cig lighter adapter and everything but I haven't hooked up the switch. In the diagram is how I plan to do it... but will having the 2 positive wires from each switch touching (in the switch) mess things up? Also should I be switching the pos or neg wires on the neons? I used a 3 in 1 adapter as opposed to just soldering the wires together so I could still keep the plugs for the neons that go into a cig lighter, incase the fuse or transformer is in there. If anybody knows how to hook up neons if you could give me some help that would be great.
