Abstract
Anordnung zur Erkennung der Schaltstellung eines Netzschalters für mikroprozessorgesteuerte Geräte. Einerseits soll der Strom durch einen Schalter nicht zu gering sein. Andererseits soll mit einem parallel zum Netzschalter liegenden Schalter eine Ausschaltverzögerung realisiert werden, welche die Abfrage der Schalterstellung nicht beeinträchtigt. Der Netzschalter (71) enthält zwei in Reihenschaltung geschaltete Schalter (7', 7"), welche nur gemeinsam geöffnet oder geschlossen werden können, wobei der eine Schalter (7") mit seinem einen Kontakt (7c) an einem der beiden spannungsführenden oder Null-Leiter und mit seinem anderen Kontakt (7d) mit einem ersten Eingang eines Sensors (11) verbunden ist, der bei angelegter Spannung und eingeschaltetem Netzschalter (71) einen Messstrom zum zweiten Eingang des Sensors (11) leitet, der mit dem zugehörigen anderen der beiden spannungsführenden oder Null-Leiter verbunden ist. Der Sensor (11) übermittelt ausgangsseitig ein Ausgangssignal entsprechend der Schaltstellung des Netzschalters (71) an einen Mikroprozessor des Gerätes. Arrangement for detecting the switch position of a power switch for microprocessor-controlled devices. On the one hand, the current through a switch should not be too low. On the other hand, a switch-off delay should be realized with a switch lying parallel to the power switch, which does not impair the query of the switch position. The mains switch (71) contains two switches (7 ', 7 ") connected in series, which can only be opened or closed together, the one switch (7") with its one contact (7c) on one of the two live or zero - Conductor and with its other contact (7d) is connected to a first input of a sensor (11) which, when the voltage is applied and the mains switch (71) is switched on, conducts a measuring current to the second input of the sensor (11), which, with the associated other one is connected to both live or neutral conductors. On the output side, the sensor (11) transmits an output signal corresponding to the switch position of the mains switch (71) to a microprocessor of the device.
