This providesthe self-starting feature which has given to the interrupter its break is quite efficient and gives very little trouble. This has been accomplished by making the magnetic circuit witha minimum amount of reluctance, and providing a properly shaped arma-ture and pole piece. The magnetic circuit is completed from the arma-ture to the base of the magnet coil through the interrupter spring this arrangement the only air gap in the path of the magnetic lines offorce is that between the pole piece and the armature itself, making thetractive force exerted o
