Claims12
An electrical switching device for power applications having a current load capacity of at least one A and having a withstand voltage of at least 100 V with two electrical connections and a switch panel connected between the two electrical connections, containing a first number of parallel-connecting current paths each having a second number of series-connected microrelay cells, wherein the microrelay cells are electrically connected to one another, forming stages with a voltage-dividing and current-dividing effect, in such a manner that the microrelay cells in one stage are joined together electrically before being connected to the next stage.
