    - einen Regler (70), der geeignet ist, den Wert (V) der gemessenen Größe (G) um einen Sollwert (Vc) herum zu regeln;
    wobei der Regler (70) ausgebildet ist, den Wert (V) der gemessenen Größe (G) gemäß einem Algorithmus zu regeln, um jede gemessene Abtastung mit einer vorbestimmten Schwelle (S) streng größer als der Haltewert (Vm) zu vergleichen und um eine ungewünschte Bewegung des beweglichen Teils (50) zu detektieren, wenn eine einzige Abtastung des gemessenen Werts (V) als Absolutwert größer oder gleichder Schwelle (S) ist,
    dadurch gekennzeichnet, dass der Algorithmus ein PID-Algorithmus ist.
  7. Elektrisches Schaltgerät (10), das eine Eingangsklemme (15), eine Ausgangsklemme (20), einen beweglichen Kontakt (25) und eine Betätigungsvorrichtung (30), die geeignet ist, den beweglichen Kontakt (25) zwischen einer geschlossenen Stellung, in der die Eingangsquelle (15) elektrisch mit der Ausgangsklemme (20) verbunden ist, und einer Offenstellung, in der die Eingangsquelle (15) elektrisch von der Ausgangsklemme (20) isoliert ist, umfasst, dadurch gekennzeichnet, dass die Betätigungsvorrichtung (30) nach Anspruch 6 ausgebildet ist.
  8. Elektrisches Schaltgerät (10) nach Anspruch 7, bei dem das elektrische Schaltgerät (10) ein Schütz ist.
  9. Elektrisches Schaltgerät (10) nach Anspruch 7, bei dem das elektrische Schaltgerät (10) ein Schutzschalter ist.
  10. Elektrisches Schaltgerät (10) nach Anspruch 7, bei dem das elektrische Schaltgerät (10) ein elektronisches Relais ist.
  11. Elektrisches Schaltgerät (10) nach Anspruch 7, bei dem das elektrische Schaltgerät (10) ein Quellenumschalter ist.
