CONTACT DEVICE

A contact device for an electric machine wherein electric current flows through a distributing ring having secured thereto a current conducting bar and a slip ring, there being interposed intermediate of said distributing ring and said slip ring an electrically conductive gasket extending symmetrically in opposite directions from both sides of said current conducting bar. The electric conductivity of said gasket increasing in opposite directions from the central line of said current conducting bar, the circumferential extent of said gasket being less than half the circumference of the adjacent side of said distributing ring.
