Method for creating and applying a cleaning voltage impulse to a stop connection and accompanying digitally controlled magnetic ignition switch assembly

摘要

The method involves producing voltage wave sequence from half-waves and/or voltage impulse in a middle voltage range, where the half-waves are decreased at a time regarding the amplitude. One of the half-waves that exhibit small amplitude in the voltage wave sequence is applied to stop connectors (53). Multiple voltage impulses are applied to the stop connectors such that cleaning effects exert on a stop switch, during generation of the voltage impulses in the middle voltage range. The voltage impulse is produced using a coil with an iron core. An independent claim is also included for a manual handling electrical device with a combustion engine.
