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.
