Bob testing an ignition switch is pretty simple, there will be one power input and the other terminals will all get power at different points of the ignition being turned.
if you can send a picture of the bottom of the switch there are numbers near each terminal that tell you a circuit.
I can use those numbers and tell you at what position they should have power.
here is a video that tells a bit about a switch as well to give you an idea.
that i understand, I was merely giving you an idea of how they are tested.
Like i said if you can tell me the prongs id on the bottom of it I can tell you what position they should have power.
yours could be like this?

Hello Lou. My name is***** would like to assist you. There are some model numbers under your seat. If you can get these numbers for me, I will check for a wiring diagram. With a wiring diagram I can help you test your ignition switch.
Is your mower a Columbia or a John Deere?
Thank you for confirming. I read your earlier post and you posted Columbia Lawn Tractor.
Do you have a continuity tester or a multimeter?
Very good! Have you removed your switch from your mower?
Let's use your continuity tester.
Look at the bottom of your ignition switch. Each one of your seven prongs will have an identifying letter either stamped into it, or stamped next to it. Look for a (B) and a (S).
Check for continuity between (B) and (S) when your key is in start position.
There should be continuity between these two terminals only when your switch is in start position.
Thank you for checking. Your results indicates that your switch is ok.
A1 powers your fuel shut off solenoid, etc. In on position, there should be continuity between B and A1.
In run position there should continuity between (L) and (A2).
You are very welcome! I do hope all goes well for you.
