STIFFENER PLATE FOR COPPER CONTACTS ON STARTER SWITCH RU (No.7931). Origin. To improve contact pressure and prevent starter failure. Report of Experimental Test. Fitted to all Exptl. cars and run 10,000 miles in France on 6-S-LV and JJ-11. This plate is a definite improvement, as we have had cases of starter failure due to poor contacts on the old switch.
