Abstract
Protection switch, especially line protection switch, whose contact parts open in front of fire extinguishing plates that are arranged perpendicular to the opening direction, comprising at least one of the parts in contact with the plane in which the ends touch, a contact angle, dividing arc slide rails to the extinguishing chamber with the extinguishing plates, characterized in that the extinguishing plates have a thickness of 2 to 5, preferably 3 to 4 mm. and the ratio of its length transversely to the extension of the arc with respect to its thickness is in a field of 4: 1 to 7: 1, preferably 1 to 1: 1, because the contact angle is preferably 30º, because the separation from the contact points of the contact pieces to the extinguishing plates, it is 3 to 8 times, preferably times the thickness of the extinguishing plates, because the arc slide rails are arranged closer together than the contact parts open and leaving separating towards the extinguishing plates approximately under the contact angle, and because means are developed for the ventilation of the arc zone in the direction from the contact pieces to the extinguishing chamber.
