I like the various different Atlas electrical switches for different model railroad applications, but I don't think the HO switch control contacts are robust enough to handle the current for an O22 switch for very long. You can try it but I suspect it will soon arc the contacts, and it's inconvenient to take those switch controllers apart to try to repair them. Why not use more heavy-duty push buttons?
I have 14 of these switch controllers that were given to me by an HO operating friend. I have 10 switches to power up. I'll try using EnginEErjon's suggested advice. If that fails then I'll try another method, including going with the original Lionel switch controllers.
