Windshield washer of motor vehicle

A system for use in a motor vehicle having a windshield, comprising:

• a first windshield wiper having a first wiper blade mounted for oscillation between first and second end positions in first and second opposite directions;
• a first windshield washer having a first nozzle which is fluidly connected to an electrically operated first washer pump for ejecting washer liquid through the first nozzle when supplied with electric current;
• a first contact base member rotatable in accordance with the oscillation movement of said wiper blade;
• a first stationary contact electrically connected to said first washer pump;
• first and second movable contacts formed on said first contact base member, each of said movable contacts being contactable with said first stationary contact to supply electric current to said first washer pump through said first stationary contact;
• said first movable contact being formed to be contactable with said stationary contact within a first range in which said wiper blade moves in the first direction from the first position to a third position which is immediately in front of the position in which said first wiper blade is in the path of washer liquid being ejected from said first nozzle, and said second movable contact being formed to be contactable with said stationary contact within a second range in which said wiper blade moves in the second direction from the second position to a fourth position which is immediately in front of the position in which said first washer blade is in the path of the washer liquid being ejected from said nozzle;
• a second windshield wiper having a second wiper blade mounted for oscillation between first and second positions in first and second opposite directions, said second wiper blade being different from said first wiper blade in wiping range over the windshield and moving speed;
• a second windshield washer having a second nozzle which is fluidly connected to an electrically operated second washer pump for ejecting washer liquid through a second nozzle when supplied with electric current;
• a second contact base member rotatable with said first contact base member;
• a second stationary contact electrically connected to said second washer pump;
• third and fourth movable contacts formed on said second contact base member, each of said third and fourth movable contacts being contactable with said second stationary contact to supply electric current to said second washer pump through said stationary contact, said third movable contact being different in size from said first stationary contact, said fourth contact being different in size from said second movable contact;
• said third movable contact being formed to be contactable with said second stationary contact within a third range in which said second wiper blade moves in the first direction from the first position to a third position which is immediately in front of the position in which said second wiper blade is in the path of washer liquid being ejected from said second nozzle, and said fourth movable contact being formed to be contactable with said second stationary contact within a fourth range in which said second wiper blade moves in the second direction from the second position to a fourth position which is immediately in front of the position in which said second washer blade is in the path of washer liquid being ejected from said second nozzle.
