Abstract: Die Erfindung betrifft einen Prüfautomaten für elektromechanische Bauelemente, wie insbesondere Kraftfahrzeugschalter aller Art, mit dem es möglich ist, derartige Bauelemente unter praxisgerechten Bedingungen äußerst zuverlässig und genau auf ihre mechanische und elektrische Lebensdauer zu überprüfen. Jedem Prüfling ist ein elektrischer Schrittmotor mit digitaler Steuerung zugeordnet. Es können Systemuntersuchungen durchgeführt werden. Eine optimale Nutzung ergibt sich durch den gleichzeitigen Betrieb mehrerer Schrittmotoren mit einer entsprechenden Anzahl von Prüflingen im Multiantrieb mit nur einer Steuerung. Beim Überschreiten maximal zulässiger mechanischer oder elektrischer Werte eines Prüflings wird lediglich der entsprechende Schrittmotor abgeschaltet, was sich besonders beim Nacht- und Wochenendlauf derartiger Prüfautomaten bemerkbar macht. Wegen der wenigen beweglichen Teile tritt ein extrem geringer, praktisch vernachlässigbarer Verschleiß auf, was sich entsprechend vorteilhaft auf die Zuverlässigkeit und auf die hohe Lebensdauer derartiger Prüfautomaten auswirkt.
