<p>The change in a contact over time is stabilized by lowering intense wear of the contact in the initial sliding stage and imparting stabilized wear characteristics from the initial sliding stage. The contacts (33, 34) of a sliding body (30) have flat tops which contact conductive segments (23) and come into surface contact with the top portions of the conductive segments (23) when the contacts slidingly contact onto the conductive segments (23).</p> |
