Abstract

351,739. Switch contacts. MASCHINENFABRIK OERLIKON, Oerlikon, near Zurich, Switzerland. June 26, 1930, No. 19473. Convention date, July 25, 1929. [Class 38 (v).] Abutting contacts 1, 2 which, owing to want of alignment, may engage one another one-sidedly, as shown in the Figure, are relieved of the resulting repulsive electrodynamic forces due to the substantially parallel nature of the current paths in the two contacts by slotting the contacts at 3 at right-angles to the current paths. The current paths are thereby caused to take a direction which, in the region of the contact faces, is substantially normal to the faces.
