Abstract
A relay has a leaf spring that is secured to a planar seating section of a yoke leg and/or to the planar seating section of the armature and has an unsecured spring section extending beyond the free end of the yoke leg or, respectively, the armature. In order to avoid a plastic deformation of the leaf spring given impacts, the planar seating section respectively merges into a convexly curved roll-off section of which the leaf spring rolls off given a blow without being bent permanently. The end of the roll-off motion is expediently limited by a detent and, in this way, it is assured that the relay does not suffer any permanent modifications of its characteristics, even given heavy blows.
