Abstract
A housing of a vacuum switching tube containing switch contacts or contact leads includes at least one insulator having a given temperature coefficient and a connecting surface, at least one non-magnetic metal part having a temperature coefficient differing from the given temperature coefficient, and a magnetic connecting part with a temperature coefficient substantially equal to the given temperature coefficient, the connecting part connecting the metal part to the connecting surface of the insulator with a vacuum-tight joint between the connecting part and the connecting surface of the insulator, the connecting part and metal part having shapes preventing destruction of the vacuum-tight joint under given maximum expected thermal and mechanical stresses, and the connecting part being free of surfaces that can vibrate and transmit vibrations to the environment of the switching tube.
