Abstract
The electromagnetic switch apparatus is housed in a two-partite casing. A partition wall inserted into the casing separates the switching magnet chamber from the switch- and connection contact chamber. The partition wall comprises a plurality of extensions which are stepped at least twice and extend into the switch- and connection contact chamber. The portions of the extensions located below the connection contact members cover in an electrically insulating manner the lower areas of the switch- and connection contact members. The upper narrow portions of the extensions extend up to in front of the connection contact members and form a protection against an accidental contact.
