Claims

[Scope of utility model registration request]

At least one pair of movable and fixed contacts, which are composed of a conductor and a contact fixed thereto, are operated to open and close within the container, and a movable and fixed contact, which is disposed in the vicinity of the contact and prevents the arc generated between the contacts when the contact is opened. Equipped with multiple arc extinguishing plates for erasing,
A switch characterized in that an arc-extinguishing plate closest to the movable contact during opening is provided with opposing walls facing the upper surface and the distal end surface of the movable contact, respectively.
