Audio jack for slip ring?

Hi all ,was watching this vid,around the 30-35 sec mark,that looks to be a audio jack ,just wandering it that was what it was,and if that would work for a slew ring for a bruder conversion mabey.

That is a ingenious way of doing that and very easy to dismantle. That would work perfectly on the lighter models. You should still use a bearing in conjunction with the plug to take some of the load. I wonder how many circuits can be had on a audio jack. Definitely cheaper than a slip ring.

That's a great idea... I was just about to attempt some sort of connection today or tomorrow because my drive motors arrived yesterday. I would think that if you used a plug from a set of stereo headphones you get 2+ and 2- connections:confused:. How much amperage would they handle in a 40-50lbs model though I wonder?

I use one in the circle drive of my grader.
Mono has two poles
Stereo has three poles (common ground, left, right)
There are some four-pole ones available, but I only found them for the smaller sizes, not the big 6.5mm ones.
Not sure about current - my four-pole one seems to work fine with the 1A to 2A I am sending over it.
They are not meant for many rotations and a bit susceptible to ingress of dirt, but they are a nifty way of doing that - for small models and large plugs, you might even get away without an external bearing to take the load.

Thanks guys, hey jensr thanks for the info,didn't know that about the stereo/mono plug. May have to swing by radio shack and take a look ,do some experimenting with it,my bruder excavator may be a candidate for it,lol.

He's definately sticking the "Keep it simple stupid'' (KISS) analogy!
