Weird problem after replacing starter

[trackfwd]

I just replaced my starter with an oem one and when I started the car it turned on like a champ,but when I turned it off with the key out it still stays on,what can it be

my guess would be the ignition switch, im guessing that there is some kind of selector in there that connects current to different points everytime you turn the key, so in this case when you turn it off it still has current. probably need a new ignition switch.
