Simple mechanical switchers like the Archer are just that. They change when you move the switch regardless of where the scan on that frame is. In the middle of the scan or wherever...it just changes and hopefully your recorder does not belch on the non-standard change. You could do the same with ganged light switches.
A real electronic switcher of the analog era waits to the end of the current scan and makes the change, so as to not disrupt the full scan, at the vertical interval point in the scan. No roll, no re-lock, and sync changes with the video...very clean and coordinated with the next frame. Sync rules in this scenario.
