When a certain voltage is applied at both ends of the coil, a certain current will flow through the coil, resulting in electromagnetic effect. Under the action of electromagnetic force, the armature overcomes the tension of the return spring and attracts to the iron core, so as to drive the dynamic contact and static contact (normally open contact) of the armature to pull in.German
Wenn eine bestimmte Spannung an beiden Enden der Spule angelegt wird, fließt ein bestimmter Strom durch die Spule, was zu einem elektromagnetischen Effekt führt. Unter der Einwirkung von elektromagnetischer Kraft überwindet der Anker die Spannung der Rücklauffeder und zieht zum Eisenkern an, um den dynamischen Kontakt und den statischen Kontakt (normalerweise offener Kontakt) der Anker einzuziehen.
