Abstract (en)
The present invention discloses that the driving coil of lower impedance having a driving tap and a common connection being electrically actuated to obtain larger actuating force is further operatively controlled by the switching device to be switched to have relatively higher impedance thus allowing smaller current to pass thereby holding electrification or excitation while required operating characteristics of the electromagnetic actuating device can still be satisfied.
