Abstract: Insertion of plug-in connections connected with cables of a first electric switch in a correspondingly shaped component of a second electric switch, so that the plug-in connections of the first electric switch and the plug-in connections of the second one can easily be connected to the motor vehicle electric network by a single counterplug eliminates the need for a separate plug housing for the plug-in connections of the first switch.

Abstract: An electric switch for operating a windshield wiper and washer system of a motor vehicle. In a switch housing a switching member is swivellably mounted around a first axis between several switching positions. A switch lever which is swivellably mounted on the switching member around a second axis which preferably perpendicularly intersects the first axis. An electric contact is movable by swiveling the switch lever around the second axis. To manufacture the electric switch at low cost and to promote a long lifetime for the two stationary contacts acted upon by the electric contact, the electric contact is held on the switch lever and acts upon the two stationary contacts at different points in at least two different switching positions of the switching member when swiveling the switch lever relative to the switching member.

Abstract: An electric switch for operating a windshield wiper and washer system of a motor vehicle has a switch housing, in which a switching member for operating the wiper system in a selected operation mode is swivelably mounted from a neutral position around a first axis in at least one optional position and a switch lever which, for operating the washer system from a neutral position into an operational position, is swivelably mounted on the switching member around a second axis preferably perpendicularly intersecting the first axis. By a single actuation, it is possible by switching on the washer system to also switch on the wiper system.

Abstract: A windshield cleaning system, in which the wiper shaft has a through-going bore, into which a pipe is inserted, in order to form a washing liquid channel for a washer system. A nozzle body is locked with the pipe, wherein in addition to the locking device a sealing device is also provided, so that even after a long period of use, no washing liquid can escape at the passage between nozzle body and pipe.
