Automotive industries . hisparticular design it is shown for use with rotating wind-ing types of magnetos, but the principle back of it isapplicable to the stationary type of interrupter as principal merits of this interrupter are the parallelmotion of the separating contacts and a very quick anddefinite break of the circuit for a very small throw ofthe arm, so that the wear and the forces due to inertiato which this interrupter is subject are reduced to aminimum. The arm is also of very light construction,having, as it does, only one projecting end from thepivot, so that the forces to which the contacts are sub-ject in closing are reduced to practically only that of thetension of the spring. Any centrifugal force at playupon the arm aids the spring. The tendency is in this type of interrupter action forthe spring to close the contacts very quickly followingthe separating action, so that this type of interrupterlends itself very effectively to battery and coil types of LOCKING SPRING INSULATED PLATE. CONNECTING SCREW PLATEFig. 15—A novel type of interrupter possessing manyadvantages. 1112 AUTOMOTIVE INDUSTRIES THE AUTOMOBILE May 26, 1921 ignition systems, because of the fact that the periodnecessary for the sparking action of the coils is veryshort and the interrupter allows a large percentage ofthe complete cycle of the action to be on closed is a decided advantage in battery systems oper-ating at high speeds. Interrupter with Tungsten and Silver Contacts During the war with Germany platinum supplies werelimited, and ignition manufacturers did considerableexperimentation with contacts made of other had been used for a number of years andhad given satisfactory results under special principal objection was that of oxidization. It hasbeen found in rotary magneto work that tungsten willfunction properly as long as the magneto is in continu-ous operation, but if the magneto stands over night withits contacts sep
