ABSTRACT:
An arrangement for coupling the armature and contact-bridge carrier for an electromagnetic switching device, such as a relay which comprises an elastic interlay interposed between the contact-bridge carrier and the armature of the relay. The interlay is shaped substantially like the frustum of a cone. The first surface or base of the cone contacts the contact-bridge carrier, while the second surface or cut-off side of the cone frustum, contacts the armature. This arrangement, minimizes the lateral shock-loading of the contact-bridge carrier when the relay is switched off so that resulting mechanical moments are kept relatively small. Further, the arrangement provides an increased level of damping.
