Hi Paul,
I've got over a dozen of these switches on my layout and although there are some finicky issues with them, I have not had this problem. I would appreciate it if you would either post the results of your efforts to resolve this or contact me directly (email in my profile) so I would know how to address this if it happens to one of my switches.
I would point out that as noted above, the insulated track pins are placed differently than the typical 022 switches. In addition, controllers must be matched with either the LH or RH switch, as they are NOT interchangeable. In any case, based on your efforts so far, it appears these are not the issues.
One last point. After I purchased one set of switches, the controller failed. It was in the warranty period offered by the seller, so I contacted the agency (can't recall which one), and they replaced the controller under warranty. Not sure if you can use that approach.
Many thanks, and good luck with your efforts,
Michael
