How do I find out if my ignition switch is faulty ?

What is your question?

I think the vehicle was giving me warning signs (hesitation at starting) but I tought it was the battery. The battery is good because I just tried another battery and starter still won’t turn

What makes this problem better or worse?

Nothing

How long has your 2012 Honda Accord had this problem?

Car just will not start. Battery is good.
