Abstract
A method for generating and applying at least one voltage pulse, which provides a cleaning effect for a stop switch, to a stop connection assigned to the stop switch, which stop connection is provided on a digitally controlled magnetic ignition circuit of an electrical device, wherein the magnetic ignition circuit generates a voltage wave series from half waves, the amplitude of which decreases over time, and/or at least one voltage pulse in a medium voltage range, wherein if a voltage wave series is generated, at least one later half wave in the voltage wave series, which half wave follows the first half wave temporally and therefore has a lower amplitude, is applied as a voltage pulse to the stop connection, and/or in that if at least one voltage pulse in a medium voltage range of 12 V to 50 V is generated, the one or more voltage pulses are applied to the stop connection and thereby exert a cleaning effect on the stop switch.
