Claims

[Scope of utility model registration request]

A link mechanism that is linked to the operation of the handle, an interlocking plate that is arranged to move up and down in conjunction with this link mechanism, and a movable contact that is inserted into an opening drilled in the interlocking plate and faces a fixed contact on the bottom surface of the tip. a movable contact that opens and closes the contact according to the vertical movement of the interlocking plate; one end elastically contacts the upper and lower surface of the opening of the interlocking plate, and the other end elastically contacts the upper surface of the movable contact to close the contact. A breaker equipped with a contact pressure spring that applies contact pressure by urging a movable contact in a pole direction, characterized in that a lower part of the opening of the interlocking plate and the movable contact are engaged with each other in an uneven manner. holding structure for the movable contact.
