Abstract

The device has two electromagnets at a distance apart acting as opening and closing magnets, each with a yoke body and coil with pole surfaces facing the armature and passage openings on the side away from the pole surfaces and a protective cap (25) for the opening spring attached to the closing magnet housing (14) at the opening via an axially insertable lock.
