How to make a circuit board? Answered

I have bought an assortment of resistors and capacitors and circuit board s, but how to make

Circuit board
I need to make a circuit board for a project. It is all 12vdc, I have a 1a fan and a 6a thermoelectric device one setting 1, plus another 6a on setting 2, and a 3rd on setting 3
So 1 is 7a
2 is 13a
3 is 19a

How to make the board.
.
Also a second device has the 1a fan plus a 4watt element, plus another 4w on setting 2, plus another 4w on setting 3
So 1 is 1a and I think 0.4a= 1.4a
2 is 1.8a
3  is 2.2a. I think

I need to know what components to use,

Right now I have each portion wired directly to the switch which is directly wired to the battery. I have burned out one of the 4watt units (I assumed it would just draw the power it needed) so I don't want anything else to burn out.

Eventually I wanted to have a rotary multiple switch controlling both sets with a neutral in the middle (if I can find it)

Printing a circuit board is next to learn,  but I already bought several boards and various assortment of components, just don't know which ones to use

Also where to buy this.       12vdc 20a 7 position off in center rotary multiple switch for sale

I don't really understand what you have and more importantly what you want to do with it.

your trying to pass FAR to much current through a switch not made for the job.

As I understand things you can't do what your trying to do you need to employ relays to do the switching.
