Abstract

Ein Schaltmagnet (10) mit einer Erregerspule, die eine auf einem Spulenkörper (4) angeordnete Wicklung (3), einen in einer zentralen Durchgangsöffnung (4a) des Spulenkörpers angeordneten Polkern (2) sowie einen in der Durchgangsöffnung (4a) des Spulenkörpers (4) axial verlagerbaren Magnetkolben (5) umfasst, wobei optional eine vom Magnetkolben (5) bewegbare Achse (7) vorgesehen ist, weist zumindest einen in den Schaltmagneten (10) integrierten Kalbenpositionsdetektor (20) auf. Dieser Kolbenpositionsdetektor (20) umfasst bevorzugt zumindest zwei Kontakte und ein Schaltelement, wobei das Schaltelement direkt oder mittelbar durch den Magnetkolben (5) betätigbar ist und bei Betätigung Kontakte öffnet und/oder schließt.
