Abstract
Electric switching solenoid valve (1) with a valve piston (9) guided in a valve housing (12), which valve piston (9) can be moved from one switching position to another switching position by a magnet armature (18) arranged in an electric coil (15). The coil (15) has coil areas (16, 17) assigned to the various switching positions of the solenoid valve (1). The coil areas are acted on by the current only during the switching operation, and the valve piston (9) is protected in the particular switching position reached by at least one holding device (19) arranged in the valve housing (12).
