Abstract
An impact resistant armature has an armature plate defining a stepped bore therethrough. The stepped bore defines a shoulder. A mounting assembly having an expanded head portion and a reduced shank portion is positioned in the bore, with the shank portion anchored to the vertical face of a door. The mounting assembly supports the armature assembly in a first position wherein the head portion and the shoulder define an initial gap. Upon impact by an intense force, the armature plate is movable to a second position wherein the head portion and the shoulder engage while the armature retains a bonded relationship with the electromagnet.
