An electrical switching device, such as a high-speed switching device, has a damper and latching assembly. The assembly is configured to dampen the movement of a moving contact of the switching device as the moving contact translates from its closed position to its open position. The assembly also is configured to restrain the moving contact in its open position. The assembly stores at least some of the energy associated with the damping process, and uses the stored energy to assist in the release of the moving contact during the subsequent re-closing of the switching device.
