Wont start have replaced starter battery in the past 3 months and agian it wont start how would i be able to tell if the ignition switch is bad

I've had the same problem, intermittent no start. The mechanic changed the battery and the Jeep ran fine for awhile. Then the problem occurred again and he found the starter was NG. About 2 weeks later, it wouldn't start. I turned the key on and off about 6 times and it started on the last try. I don't know why, but my gut feeling is there is something wrong with the ignition switch or the key. The mechanic's diagnostic equipment says everything is fine. I deceided to use a different key for awhile (my wife's key) and see what happens. It's about 10 days now and everything is O.K. I've had the same problem, intermittent no start.
