View Full Version : [Question(s)] Help with electro mechanical control of rocker switches

I'm trying to design a mechanism to control a bank of six rockers switches using external control (servos, actuators). Would appreciate some brainstorming help with the transfer of motion involved in this project. These would be laid out in a vertical orientation about 6" in height with the rocker switches operating laterally. The project is using Dynamixel AX12a's for some other functions.

Thank you for your help!

With 2 servos: one servo moving slider on axis (like printing carriages in printers) and second servo rotating axis in both sides and slider swithing rockers switches. May be it is possible to make it with 1 servo, but some kind of "movement coding" like in locks will be needed, probably.

Thanks for the suggestion- with that in mind, it looks like the Igus DryLin mini might be perfect for this. Here it is used to make a camera slider:

What do you guys think is the best mechanism to flip the rocker switch? Another servo mounted on top of the DryLin carrier?

May be two solenoids on two sides of carriage will be more easy solution. One solenoid will turn current switcher on and another one will turn it off. http://www.trossenrobotics.com/p/small-solenoid.aspx

I would look at cheap "park flier" hobby servos. Just use one servo per switch you want to move. Mount them all into a frame for stability, and mount the frame over the rocker switch assembly. Use something like a Micro Maestro, or an Arduino, to control the servos. With luck, the standard horn on the servos is reasonably matched to the action of the rocker switches.
