Abstract

PURPOSE: To improve interrupting capacity by providing a fixed contact piece with a 1st slit having an open end at one side end of the fixed contact piece and a 2nd slit extending from the closed end toward a fixed contact point side and passing between the fixed contact point and the other side end of the fixed contact piece.
CONSTITUTION: Providing a fixed contact piece 8 with slits 13A and 13D, current entering from a terminal 8C is made to flow between the slit 13D and a side end 8E of the fixed contact piece 8, to make a U-turn and to enter an arc 12. In this way, since there is little current component flowing from the right side of the arc 12 into the arc 12 and almost all the current enters the arc 12 from its left side, a drive force F1 becomes smaller than an arc reverse drive force F2 caused by a fixed contact piece current, the arc 12 is driven to the F2 side and runs on the fixed contact piece 8 in the direction of the arrow P. Constituting in this way, contact point wear can be reduced and at the same time interrupting capacity can be improved.
