The triangular projected part 10a is disposed so that it is projected on the back of the plane where a movable contact point 1a of the movable contact 10 is placed. When the circuit is opened, only one slope in contact with each other at an apex of a triangle comes together with the pin 8. At the same time force of reaction from the pin 8 is applied in the direction toward the tip of the movable contact 10 as the arrow C indicates.
