Description

For my Vertibird remake project a few years ago, I required a slip ring to transfer electricity from  the stationary base to the spinning device that had a motor.  My solution was to use a stereo phono jack and plug.  It has 3 conductors and once connected together, they spin freely but keep tension so they don't come apart.  No audio... Only DC amps!  Abusive to say the least!

A slip ring is an electromechanical device that allows the transmission of power and electrical signals from a stationary to a rotating structure. A slip ring can be used in any electromechanical system that requires rotation while transmitting power or signals. It can improve mechanical performance, simplify system operation and eliminate damage-prone wires dangling from movable joints. Wikipedia
