ABSTRACT:
An electromagnetic switching arrangement for operating a control device, with the arrangement having two electromagnets (1, 2) which are formed respectively from a coil (3.1, 3.2) and a magnetic yoke (4.1, 4.2), are connected to an actuatable direct-current supply (9), and are spaced from one another, with the pole faces (5) of the two magnet yokes (4.1. 4.2) facing one another. An armature (6) is disposed between the two electromagnets so that the armature can move back and forth between the pole faces (5) of the two electromagnets. The armature (6) is connected to the control device to be operated and is held by spring elements (8.1, 8.2) in an inoperative or neutral position between the two electromagnets (1, 2) when both electromagnets are currentless. At least the armature (6) is made of a material that contains a residual magnetization.
