Abstract
A brush and slip ring assembly in which specific resilient characteristics are developed in the brushes by forming them in shapes which will allow the brushes to be simultaneously displaced a finite amount with the slip ring assembly in a vibratory environment which would otherwise produce relative sliding motion therebetween. By preventing the relative sliding motion between the brushes and slip ring assembly, the formation of electrically insulating friction polymers on the points of contact between the brushes and slip rings is inhibited.
