Abstract
A contact assembly including a first contact member electrically connected to a first electrical terminal, a second contact member electrically connected to a second electrical terminal, and a third contact member movable into and out of contact with the second contact member. An elastically deformable fourth contact member ensures electrical contact between the first contact member and the second contact member and the contact assembly is configured such that the fourth contact member is increasingly compressed between respective abutment surfaces of the first contact member and the third contact member as the third contact member moves towards the second contact member, thereby resiliently deforming the fourth contact member. Also, an electrical circuit breaker and an electrical switch, respectively including such a contact assembly. Further, a vacuum interrupter including such an electrical circuit breaker.
