Atlas corrected the wiring problems as well as other with the second (?) release of switches. You can identify them because on the box it says "UV protected". It is also cast into the underside of the plastic ties.
The "problems" with Atlas switches comes up frequently. It is a rehash of problems from many years ago. As long as you buy new production you will be fine. Be wary of buying used and off ebay. Check for UV protection.
Trainworld has O54 switches for $80.
Thanks for the tip on the UV marking on the newer boxes. I agree with you on all counts. As you say, I think a lot of folks still refer to problems with the original releases of the Atlas switches. I have not had any problems with their newer switches.
