<p>A male contact assembly for high voltage switching applications includes an elongate male contact with an electrically conductive extension arranged concentrically with the contact and extending longitudinally therefrom. A layer of electrically insulative material overlies the contact extension and arc-quench-ing material overlies such electrically insulative layer. The electrically insulative layer is more resilient than both the extension and arc-quenching material whereby the assembly can withstand greater cantilever stressing prior to fracture of the arc-quenching material than an assembly lacking such resilient layer. On such fracturing, the electrically insulative layer isolates the contact extension and contact from electrical arcing.</p> |
