Car started put won't turn off with the key!

[ShoGuy93]

Ok i have a problem with my red 95. I went to start it up yesterday. I put the key in and went to start it. But at the point where it cranks it did nothing. So I turned it harder and i had to go way over to get it to start. And it felt like something was grinding when i got over that far. So it started up and then the key or ears i guess you would call it is like all free moving and i couldn't get it to shut off. So i finially killed it. I pulled my ignition switch out with key and all. And i don't think that is the problem i switched it out with the one from the silver bullet. And it didn't fix any thing. It wouldn't turn the red sho off. I think it is the white box where all the ignition wires go to on the lower column... What is that thing called? Cause when i try to turn it over it just grindes and when i do get it to start. The ignition siwtch is all free flowing and really easy to turn and you can't turn it off. So i have came to think it is the white box with all the wires going to it under the column. Cause from looking at it, the white box has a bar (or a switch i guess) that goes into the column and then there is i guess another bar type thing that is in the column that moves the bar that is in the white box. And that moves the bar either starting the car or killing the power. But when i pulled my white box out you can feel it it grindes when u push the bar all the way over ( Trying to start it). What is this "White box" called. I'm really sorry if i rambled and i'm sorry if i confused any body just trying to explain what i think it is and does. If any body has any input please respond asap. O and if you know what this is called how much does it run?

Thanks always
Brad

isn't that the ignition switch with all the contacts and stuff inside? The key lock actuates the switch (white box). I replaced it on my Aerostar a while back when it wore out.
