Image Number 11 for United States Patent #8576042.
A miniature circuit breaker has a housing formed of a housing base of insulating material and a pot-like housing cover, which is or can be positioned onto the housing base. Two elongate and flat contact arms are partially embedded in the housing base parallel with respect to one another in terms of their longitudinal direction. A fixed contact is arranged at an inner end of a first one of the contact arms. A bimetallic snap-action disk with a free end, forming or bearing a moving contact, is fitted at an inner end of the second contact arm at a fastening point. The fastening point, the moving contact and the fixed contact are in this case on an axis which is parallel to the longitudinal direction of the contact arms.
