摘要：
An operative control circuit of multiple electromagnetic actuating devices in series and parallel connections, wherein individually installed driving coils of two or more than two electromagnetic actuating devices being operatively controlled by a switching device to appear lower impedance in parallel connection or series and parallel connection for electrification thereby producing a larger electromagnetic actuating power is switched to appear relatively higher impedance in series connection or series and parallel connection thereby reducing currents passing through driving coils while required operating characteristics for individual electromagnetic actuating devices after electrification are still satisfied.
