Well, I took apart my A61 swivel. All it is, is a small wire connecting the male center pin to the female center socket. Nothing magical. The outside casing is the ground. There are 2 retaining clips, 1 on each end that hold the guts in. The female end has what looks to be a crcuit board from the outside, but it isnt. It just mounts the female socket. Its actually amazing that the wire doesnt break with the adjustment of the angle.
