The lamp is thus short-circuited, the current passing from the + point through levers A and C to the cam D and outward at the - - point. To give the lamp sufficient current to produce one-half its full light, the cam D is... moved fur- ther to the right, so as to pass from its contact with lever C. Then lever C, falling further, forces, lever A to make connection with lever B, and the current divides, a part flowing from the -f- point through the coils of the magnet and the lamp outward, and the remainder flow- ing, by way of levers A and B and resistance I, outward to the point. With the cam turned to the interme- diate point the lamp is extinguished. Turned as far as it will go to the right, one-half of the light is emitted.
