@Norton posted:You can use the micro switch. If you mounted the Cruise Commander in the engine you only have to wire the switch to the chuff in pin and one of the ground pins. No need to run wires to the RS board in the tender. You will still only get two chuffs because the engine has a two lobe cam. The smoke is synchronized because the axle cam also lifts the smoke unit piston. I used the leaf switch, but connected the two leads to the RS Commander.
If want 4 chuffs per rev you would have to use something like John's chuff generator in the engine. Otherwise its reed switches and magnets in the tender. You lose synchronized smoke since the cam still drives the piston. Only way to to get 4 chuffs and puffs is to replace the puffer unit with fan smoke unit and even more circuitry.

@gunrunnerjohn posted:Any switch connected to the ERR RailSounds Commander chuff input MUST BE TOTALLY DEDICATED to that task. It's not possible to share that chuff switch with anything else. The circuit on the RS Commander does not have a common DC ground with the rest of the world.
I you really want chuffing smoke and synchronized sound with a fan driven smoke unit for TMCC, consider the Super-Chuffer II. It's purpose built to do that job and it does it very well. Here's some videos with folks that are installing the Super-Chuffer. Thanks for the videos. I would love to have that for this engine, or any for that matter. But as I said, I can't, due to NO SMOKING orders from the boss. And after 59 years, I still lo.... err, follow orders.
When I connected the existing leaf switch to the RS Commander, for some reason I got 2 double chuffs per revolution and was looking for a lead as to why or where to look for some error I made. Chuff-Chuff.....Chuff-Chuff per rev. Also, is the correct situation for a sensor switch to be a normally closed like this one is? It would seem to me that it would be a normally open switch that was momentarily closed each time the cam moved the arm of the leaf switch.
