These crossings were of the earlier manufacture with the four center rails in continuity through the diamond, I removed this diamond and made one out of two K&S Metals brass bars with a soldered lead wire attached. The normal straight through and 22.5 degree crossover are to be powered separately. My plan is to have the diamond powered by the normal straight track or this diamond is to be powered by the 22.5 degree crossover track. I also want to eliminate the possibility of a short, all outside rails are wired in common, on the powered center rail and diamond is the issue. I need assistance in determining what type of toggle switch should be used and how to wire this switch with the diamond lead wire, the center rails adjacent to this cross over have solder wire leads. The straight normal track and the 22.5 degree crossover track to be controlled by two transformers.

I agree with Susan - I used DZ1008's to power the diamond on a large crossover. The relay was connected with the turnout machine toggle switch. If I remember correctly one set of rails is always on for one direction while setting the turnout for opposite curve turns off those rails and turns on the opposite rails. Having one set rails constantly on for straight through traffic does not matter since the locomotive does not touch the diamond. Below is a diagram for the Ross crossover. Hopefully you can use it as a reference for your track.
