Replaced it becuase the old switch was bad. Lights wouldn't turn on at all. The new switch works when its not installed. If you push the ball on it they shut off. The old switch did nothing. I tested both while I had them out. Plugged them in to the harness and tested. The new ones works when its not screwed into the 6 speed transmission. It does nothing when installed. Can the piece thats in the transmission that pushes it be broken or how does it work inside the trans?
