Abstract (en)

[origin: WO0141174A1] The invention provides that, in an electromagnetic switchgear, the travel-time behavior of the contact carrier (5) is measured using a magnetic field sensor (10). To this end, a microprocessor (16) evaluates the output signal of the magnetic field sensor (10) and determines the velocity of the contact carrier (5) or of a part which is interactively connected in a fixed manner to the same. The microprocessor (10) controls the current of the coil (3) of the electromagnetic system according to said evaluation and determination. The invention also relates to a corresponding method and to a circuit.
