ABSTRACT:
An electrical protection switch, or circuit breaker, includes a movable contact part rotatably seated on a bolt which is secured to a leg of a mount. The other leg of the mount lies against a flange of a coil member which forms a portion of a magnetic release means. Two retaining elements extending parallel to one another and mutually spaced apart project from this flange. The retaining elements accept one leg of the mount therebetween and are provided with resilient tongues which press against the leg of the mount lying against the flange and, thus, press the leg against the flange. Fastening of the mount having the movable contact part to the magnetic release means, or coil member, is performed simply by slipping the mount onto the coil member by a snap-in connection.
