Abstract
In arc interrupters having fixed and movable contacts and a fixed annular electrode surrounded by an arc-driving coil, the problem of electrode collapse owing to the magnetic forces generated in the electrode and the coil is reduced or obviated by providing the electrode with at least one flange which is supported against distortion by ferromagnetic material which forms part of a magnetic circuit produced by the coil when it is part of an arc current path.
