Hello,
In here :
http://www.diyaudio.com/forums/parts/115531-how-remote-control-rotary-switch-based-attenuator.html
I have tried to discuss about remote control of a rotary switch, but I think it is in the wrong directory.
After trying different volume control units, like LDR, R-2R network with small signal relays and mercury wetted relays, I still use the shunt volume control with a rotary switch, because in my experience it is much better.

Now again I turned back to remote control it somehow.

The stepper motor on the axle of the rotary switch does not work well.

Now I think about using RC servo to move a step. It would be good if I could find an electric operated clutch, which has an axle going through inside and the outer gear is either connected to the axle or not connected, depending on if it is actuated or not.

Do you have any idea?

Thanks,

JG

Have you got a spare wiper and contact available to tell the controller it is home? If you have, one could use a low geared motor, driving the shaft of the switch. Using the contact to tell the microprocessor to stop the movement of the motor or if the remote is still being pressed to ignore the stop command. You could even arrange direct access from that simple circuit.

Hello,

That is not accurate enough. I made a disc with small holes on it. With cnc drill. I can sense the position, that is not the problem. I need to move, while I can still rotate by hand, that is my problem.
I'm thinking using two servo. One to engage with the axle, the other one to rotate given angle.
There must be a more simple and reliable solution....
