  • Electrical contact arrangement having a first and a second contact piece
    Patent number: 7699666
    Abstract: A first contact piece and a second contact piece interact to give a contact configuration. The second contact piece is singled-sided and can be reversibly deformed. In order to increase the contact pressure of the second contact piece onto the first contact piece, an additional pressure element is provided. The pressure element generates contact pressure acting upon the second contact piece via a deflecting device.
    Type: Grant

  • Vacuum circuit-breaker and a method for controlling the same
    Publication number: 20040061504
    Abstract: The aim of the invention is to improve the interrupting capacity of a vacuum switch, to achieve this, the contact parts (4, 5) that can be displaced in relation to each other are separated at a variable speed. Separation takes place in such a way that during a predetermined time period a predetermined distance between the contacts is not exceeded. To prevent said predetermined distance from being exceeded, a braking element is allocated to the vacuum circuit breaker.
