Abstract
The actuation speed of an electromagnetic consumer is increased by means of a charged capacitor which is connected in series with a consumer at such a polarity that its voltage is added to that of the power source. In one embodiment, the capacitor is switched across the power source until it is charged and then it is connected in series with the consumer at such a polarity that its positive pole is grounded while the negative pole is connected to the consumer. In another embodiment, the capacitor is first charged through the electromagnetic consumer and then it is connected with its positive pole to ground and with its negative pole to the consumer.
