Just a point of clarification. Yes, all 13 had a wire order or assembly error. That error specifically was that Aux power and Track were reversed compared to the outside labels stamped into the metal cover.
As delivered with the jumper installed, they would work out of the box on track power. However, if you then removed the jumper and wired to what you thought was Aux power, you would be shorting your Aux power into the track 3d rail, and no power to the switch.
Again, out of the box, a person could unwittingly test these switches with track power, even use them with track power and be completely unaware. However, later, when they attempted to use Aux power or had an issue using track power via the jumper due to folded tab contact failures in the switch, then that miswire or terminal order vs labels becomes a very big deal.
