摘要
The yoke arms are connected with each other by a permanent magnet. A movable closing armature is exposed to a resetting force a littler smaller than the attractive force produced by the permanent magnet flux. A control circuit is wound on the yoke and generates a flux sufficient for the movable armature release. At least one of the magnetic circuit arms (2,3) is doubled and forms two contact surfaces for the movable armature. The control circuit (6) is wound only on the doubled arms(s), and the resetting force is applied to the armature (5) at the barycentre of the attraction forces holding the armature at rest.
