Turn signal cam

I just replaced the turn signal switch in 65 Dart. When I turn wheel it won't trigger the cancel cam, it's like it doesn't come close to tripping it. Pulled it apart put back on and doesn't appear to make contact. Everything else works, electrical is fine , contacted company ( Classic Body Parts) and waiting to hear back. Any one else have that problem with new signal switch's?

Every single one.... they all needed the ears manipulated. I use a match to heat the engineering plastic so it will move and stay.
