Abstract (en)
[origin: EP0369807A2] A miniature circuit breaker is disclosed with has a double biasing connector which can bias the movable contact to either the off position or to provide contact pressure in the on position. Switching between effective directions of action is achieved instantaneously and is effected by operation of an operating handle in the miniature circuit breaker. The double biasing connector may take the form of a spring acting on a movable contact via a switch arm pivotally connected to the movable contact. If the free end of the switch arm is held by the operating handle, the spring provides contact pressure, however, when the switch arm is released by the operating handle, the spring acts to pull the movable contact to the off position.
