Abstract
The detection of the switching state of a stop switch at a switch terminal of an ignition device for an internal combustion engine is provided, in which an ignition pulse for controlling an electronic ignition switch is generated and a first power storage device is discharged via an ignition coil and during this discharge a voltage signal having negative and positive voltage half waves is generated, which is used for synchronizing a sampling, representing the switch state of the stop switch, particularly its closed position, of a voltage value at the switch terminal.
