Some of mine are getting older. I ran short jumper wires to help the switches. If you use rail clamps like I do, you can use those clamps to attach the wire jumpers. I made mine pretty short as they connect to the closest power points. Someday, I should take one off and snap pictures of what I did.
It's good practice when building layouts in any gauge, to help the switches power paths when they're required to carry larger amp loads. I like to run large consists with many engines drawing power from the rails. Some switches can't carry all those amps even when new.
