Abstract

An electromagnetic valve, in particular switching or pressure regulating valve for an automatic transmission of motor vehicles has a magnet housing, a magnet coil with a coil body received in the magnet housing, a valve member, a magnet armature through which the magnet coil cooperates with the valve member, a valve closing part connected with the magnet housing, electrical contacts for controlling the magnet coils and arranged outside of the magnet housing, and conductors extending through the magnet housing and connecting the electrical contacts with the magnet coil. The magnet housing is composed of at least two magnet casing elements, including a first magnet casing element and also a second magnet casing element which at least partially overlaps the first magnet casing element, at least one of the magnet casing elements having a recess through which the conductors extend to the electrical contacts.
