I'd guess your talking about the method with a slide switch and linkage?
The turnouts can be at any angle. The throw bar hook and rod that run through the bench work will be in line with the turnout and when you mount the little switch plate under the layout it is the only part that has to face the layouts edge. You can rotate the bottom plate 360 degrees and it will still work.
I will mention. I don't use steel wire for the bottom spring, I use brass so it solders easier. And you can use a RC car ball joint link on the switch if you like. The way to align these is to center you points, I just use 2 small pieces of styrene. Now center the slide switch and insert the spring. Once it is all centered solder the spring, remove the shims and test it out.
Sounds complicated, but once you make one you will really get the hang of it. I like having the pull knob at the layout edge and these route power to the frog. A little labor to make them, but they are very cheap.
