ABSTRACT:
A bent roundabout current path (8d) rising in the shape of an inverted U is formed between a horn portion (8a) and the end portion of a fixed contact (1) where an arcing horn (8) is joined to the fixed contact (1). An arc (12) is subjected to the electromagnetic force directed to an arc-extinguishing chamber side from the magnetic field H of an current I flowing through the arc-(12)-side conductor portion of the roundabout current path (8d). Therefore, the moving-contact-(4)-side foot of the arc (12) is retained in the leading end portion of the moving contact (4) and not returned to the movable contact (3) side.
