getting rid of the ignition switch

I've brought this up in the past: I had several ignition switches that burnt and now, the new one was defective straight out of the box! it's like a curse

I don't understand why something that should be electrical has to be implemented in a ridiculous mechanical way: if you follow the path from the key to the actual switch wires, it's a stupid design and a couple relays and switches would make it simpler.

So, I'm trying to figure out what is the max intensity I should expect to go through the relay for 1) when the power is on and 2) during cranking.

Also, if anyone has done this, where did you mount the switches? I can't think of a convenient spot that is clean, and out of the way.

I would like to know how many they have made and how many have failed. ;) It seems like the best way to accomplish what they set out to do in my opinion instead of having multiple keys and switches and to use less wiriing and electronics.
