Switch to change from motor to manual

[zumaidi]

The switches to change from motorized to manual control on my Flight Simulator.

 

 

 

I added this feature so that ones can still play when run out of batteries.

 

In addition, sometimes ones need the motors for other MOCs. :-)

 

I have submitted this MOC to LEGO Ideas - https://ideas.lego.com/projects/d3c9edc7-1a3c-4ea3-8b5d-4dbe1fc0faa6

 

Hopefully I can get your support.

 

Thank you very much.

Is there a reason you did it this way instead of putting in a changeover catch?  I can't quite tell how all the gears are meshing but won't this tend to disengage on its own when the motor is on?

You should also add this to the topic about the original mechanism rather than creating a new topic for it.

Thank you. I don't think I have enough and required parts to make changeover catch. I will study on it more. 

So far, based on more than 3 hours playing with it, it worked fine and no disengage. I believe this is because the force is not hard because the motor just need to rotate the actuator.

Thank you. I made a new topic because I believe the same kind of switches can be applied on any other builds, not necessarily specific for my Flight Simulator.

Nice solution.

Did you know that a differential can do this too? it allows a manual dial on one axle and a motor on another axle to drive some function, but the dial does not move the motor and the motor does not move the dial.

The L axle in the diff is input 1, R axle is output and then the axle driving the differentials case is input 2.

The lambo paddle shifter works in the same way too, but it does not use a differential. you can move the two knob wheels that are on a 3L axle and it will change gear but the paddles will remain stationary.

Thank you for the explanation. I did not know that.

Although it looks too technical for me, I will study this further. 

May be there are some videos on YouTube. 

Thanks again.

That's not quite that simple. The motor has an internal brake and does not backdrive easily, but you do need to take measures to prevent the motor from back-driving the manual input.
