ABSTRACT:
The breaker mechanism (6) has a position to either side of a zero position and is distinguished in that it has a minimum number of few parts, and that it can be assembled from only one direction. This ensures a trip-free mechanism. Conversely, switching on is impossible when the breaker mechanism (6) is unlatched. The breaker mechanism (6) has an intermediate piece (15) that is assigned an alternating function in reference to the two positions. Together with a rotary handle (12), it forms a toggle lever joint with two effective ends.
