ABSTRACT:
An electric high-voltage circuit breaker is provided with two coaxially arranged contact members, which are movable relative to each other, with one rated-current contact (5, 7) and one burning contact (5, 7) each. The rated-current contact (7) and burning contact (7) of one movable one of the two contact members are frictionally joined to each other via a support part. The end, turned away from a stationary one of the two contact members, of the rated-current contact of the movable contact member is in contact, in a sliding manner, with a current supply of this contact member. This breaker is to be further developed in such a manner that the use of an additional sliding contact between the burning contact and the current supply can be omitted even when switching extremely large currents. This is achieved by the fact that the rated-current contact of the movable contact member is formed by contact fingers which are elastically supported on the support part (18) and that the support part is constructed to be electrically conductive and has a contact surface which acts in conjunction with the contact surfaces of the contact fingers after separation of the rated-current contacts. Such a breaker is preferably used as a generator switch.
