Rotary electrical contact device

摘要

A rotary electrical contact device includes a stationary member configured to be coupled to a base, and a rotatable member supported for rotation relative to the stationary member and defining a center opening. A raceway includes a plurality of axially spaced annular contact rings supported by one of the stationary member and the rotatable member. A blade tower includes a plurality of axially spaced blade assemblies and is supported by the other of the rotatable member and the stationary member. Each blade assembly includes a radially extending contact blade in electrical communication with one of the axial spaced contact rings of the raceway.
