Vacuum chamber for low power switching, has sintered structure applied to inner surface of cylinder lid to form fixed contact

摘要

The vacuum chamber has a contact carrier for a fixed contact and moving contact carrier for a moving contact. The contacts are made of a sintered structure formed from two materials. An insulating cylinder is closed with a lid at each end. One lid (12) forms the fixed contact carrier. A sintered or smelted structure is applied to the inner surface of the lid to form the fixed contact (18). An Independent claim is included for a method of manufacturing a fixed contact inside a lid for a vacuum chamber.
