circuit board Answered

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

So what do you want your circuit board to do? You have a bunch of varying loads that require different amounts of power, dunno what kind of power supply, throw in a rotary multiple switch...

right now I use a different toggle switch for each because they are all setup for lead to switch to the battery,. there's nothing regulating the power and I burned out one of the 4watt parts, (I thought it would just pull the power it needed).
