What is a Slip Ring?

A slip ring is  It ensures the current from a stationary wire keeps contact with the wire that needs to turn or rotate.

A metal rings used when a machine or device needs to supply power, or a signal, but also rotate at the same time. It provides a continuous electrical connection through brushes on stationary contacts.  Brushes are an integral part of any slip ring design.  The brushes, which often look like the end of a paintbrush, are metal conductors that drag on the outside of a metal ring. As the device rotates, the brushes conduct the electrical current, or signal. Without the brushes, the slip ring can’t conduct the electricity or current needed to function.
