Electric vacuum switch

摘要

The invention relates to a vacuum switch with cup-shaped switch contact components having an obliquely slit contact carrier and mounted unslit contact ring. The contact carrier consists of copper with or without additional chromium and the contact ring consists of a chromium-copper matrix with or without additions. The electrical conductivity changes rapidly from the contact carrier to the contact ring by a factor of at least 3. The invention is useful for high power vacuum switches.
