<p>The self-cleaning dual electrical contact between a moving conductor 1 and two fixed conductors 2, 3 is established through a crank/connecting rod mechanism 15, 16 by way of a preloaded spring 18. At the end of the closure stroke a drive component 24, 26, linked to the crank, rotates an oscillating component 5, 11, 12 which provides for the gliding 29, 30 of the moving conductor over the fixed conductors under a pressure comparable to the normal working pressure. <IMAGE></p> |
