Here is the thing.. Ohms lay applies here.
What is "Ohms lay"? Do you mean Ohm's Law?
if the resistance even is very low... e.g. 0.01Ohm for contact 1 and 0.02Ohm for contact 2 you must see a big current difference. Contact 1 will have 2x the current than contact 2...
Maybe if you are designing arc welders or blast furnaces. Is that what you are asking about? thousands of amps?
This can even cascade if that current in contact 1 is more than the rated current.
That can happen in ANY circuit. Even if you are NOT paralleling contacts.
Any thoughts?
You don't appear to understand Ohm's Law well enough to ask a Real World question.
If you are asking about some actual project or design, provide the necessary details and we can help you understand what you can and can't do with parallel contacts.
