Beware of used switches.
As I mentioned in the previous post in this thread, I was attempting to find a supplier for my final expansion. To the notorious internet and that famous site that we can't mention. Found a supplier for an O-72 switch. Ouch. The price with tax and shipping was almost $150. But I felt desperate and pulled the rip cord. Upon receiving it this vendor had left an original price sticker on the box. It read $37. Wow did my antennae go up! I had not paid that price in many years and thought I had not paid that price in a very long time. I also revisited the vendor's description and yes Ias I remembered "New in the Box" was used. I thought I should make one final check. Removing the switch from the box, I turned it over and there was not any indication of new heavier wiring or strapping. This may have never been removed from the box but the term "New" should not have been used. Luckily the vendor was very accommodating and returned the full price including shipping and gave me a return shipping label. So I very much agree with your assessment regarding "Used" but I would go further and include "All Atlas switches until investigating the reverse side".
