Electric switch for drive system to drive wiping brush of glass panel of car, has guiding unit placed downstream from contact blade in rotation direction of drive wheel, where unit guides lubricant in trajectory zone

摘要

The switch has a drive wheel (9) presenting a conductive track (19). A contact blade (21) is attached with the conductive track. A lubricant (23) is placed on the conductive track on a trajectory zone (25) of the contact blade. A guiding unit (27) of the lubricant is placed downstream from the contact blade in rotation direction (A) of the drive wheel and configured to guide the lubricant in the trajectory zone after contact of the contact blade on the conductive track. The guiding unit comprises two guiding arms (33) on two sides of the trajectory zone.
