ABSTRACT:
The object of the present invention is a direct current-operated electromagnet.
The branch of the armature which penetrates the coil body cooperates with a fixed core branch in three distinct successive modes due to the action of different air gaps.
It can advantageously be used on relays for automatic equipment or on small contactors whose number of contacts is variable and/or subject to time lags.
