(57) Abstract Objective With simple configuration, degradation of the contact breaker points by the arcIt prevents, it offers the contact breaker points opening and closing feature whose life is long. Constitution In fixed armature 16 arc runner piece 17 providingru. Electromagnetic power F and the above-mentioned arc run which are generated depending upon the magnetic field dWith by na piece 17, arc e1 is moved by arc e2,ru. Because of this, arc e2 traveling contact 7a and fixed connectionThere are no times when it concentrates with respect to the shortest distance of 0.6 a. In addition, aArc e2 is absorbed from the side by kuranna piece 17,It becomes arc-shaped and is extended. Because of this, the arc e which is extendedWith 2 the damage to traveling contact 7a and the fixed contact 6the decreaseLittle it does.
