Abstract (en)
The present invention is disclosed by that the power source device with variable output voltage is operatively controlled by the switching device to provide higher voltage power to the driving coil installed in the electromagnetic actuating device so as to produce larger electromagnetic effective force, wherein the power source device with variable output voltage after actuation is operatively controlled by the switching device to be switched to provide lower voltage power thus allowing smaller current to pass through the driving coil thereby holding electrification for excitation, while required operating characteristics of the electromagnetic actuating device can still be ensured.
