Abstract

A magnet coil which is disposed in a cup-shaped housing that has stub for carrying magnetic flux to a magnet armature; the positioning of the magnet coil inside this cup-shaped housing is defined by an insulation spray coating, and the magnet coil has contact terminals which protrude to the outside, having been spray-coated with insulation, through the bottom of the cup-shaped housing. The bottom of the cup-shaped housing also has a third opening, which is likewise filled by material and which offers an opportunity, during the spray-coating, of introducing a rodlike part to support the magnet coil.
