摘要： An interrogation of a switched state of a switch is carried out with a high interrogation current until a closed switch is detected. The following interrogations of the switched state are then carried out with a low interrogation current until a definable time period which runs starting from a detection of the closed switch or until a definable number of interrogations which is counted starting from the detection of the closed switch is exceeded. After the expiry of the time period or the number of interrogations, the interrogation is continued with the high interrogation current until a closed switch state of the switch is detected again.
