Abstract
An electric circuit interrupter including a pair of electrodes, one of the electrodes being relatively movable with respect to the other into and out of engagement with the other. At least one of the electrodes comprises an annular contact section and an arc driving section surrounding the annular contact section. The arc driving section is formed with a plurality of slots inwardly extending from the outer periphery of the arc driving section to divide it into arc driving segments. The slots are inclined at an angle with respect to the radius of the arc driving section and also inclined at an angle with respect to the axis of the arc driving section such that the arc driving segments can overlap the adjacent arc driving segments across the inclined slots.
