Track or Switch Problem

 I didnt get a phot of that buti I am running two loops of track together on my small layout. I have them connected with 4 031 switches. The two inner loop switches do not work unless there is a car on the track. However, as soon as the car enters the track between the switches they shutdown. I used a piece of wire and jumped the outer rail to the outer rail of the track that runs between the switches and the powered on. How do I fix this problem? Help would be appreciated.
