In a vacuum interrupter for circuit breakers, the aim is to reduce the contact pressure force. The contacts of the vacuum interrupter are configured for this purpose such that there is arranged inside an outer contact region, serving the purpose of arc quenching, an inner contact region which includes a plurality of resilient contact tongues arranged next to one another on a divided circle.
