An electromagnetic actuator for operating a driven component includes first and second electromagnets having respective first and second pole faces oriented toward one another and defining a space therebetween; an armature disposed in the space and movable back and forth between the first and second pole faces; a driving component attached to the armature for moving therewith as a unit; and a resetting spring assembly coupled to the armature and exerting forces opposing movements of the armature caused by electromagnetic forces generated by the electromagnets. The resetting spring assembly is in a relaxed state when the armature is in a mid position between the first and second pole faces. A coupling device connects the driving component with the driven component for effecting a transmission of pushing and pulling forces from the driving component to the driven component to cause displacements of the driven component as a function of displacements of the armature and the driving component. The coupling device includes a length-compensating arrangement between the driving and driven components.
