I'm sure you mean well, but there are no switches on any 7CT1N that are immediately behind the front panel. The shaft in question is six inches long, as I already stated. It is already obvious that the cleaning material should be introduced directly into the switch, not via gravity feed from the front panel, which is entirely infeasible. I have already done everything mentioned here with no improvement whatsoever. Evidently the issue is mechanical damage to the small rod's track.
