Abstract
A closing spring assembly for an electrical switching device is provided. The closing spring assembly is configured to exert a closing force on a moving contact of the switching device. The closing force helps to maintain physical and electrical contact between the moving contact and an associated stationary contact, so that the moving and stationary contacts form a path for conducing electric current through the switching device. The closing spring assembly is configured so that the closing force remains constant or decreases as the moving contact is driven away from the stationary contact during switching of the current path away from the moving and stationary contacts.
