    Abstract: An exemplary vacuum interrupter for a circuit breaker arrangement including a cylindrically shaped insulating part, within which a pair of electrical contact parts are coaxially arranged and surrounded concentrically by the insulating part. The electrical contact parts can be configured to initiate a disconnection arc only between corresponding inner contact elements after starting a disconnection process, and corresponding outer contact elements can be configured to commutate the arc from the inner contact elements to the outer contact elements until the disconnection process is completed, wherein each inner electrical contact element is designed as a TMF-like contact element for generating mainly a transverse magnetic field, and each outer electrical contact element is designed as an AMF-like contact element for generating mainly an axial magnetic field.

    Abstract: A movable contact for a rotary switch is provided. The movable contact includes first and second contacts for contacting a stationary contact, where the first and second contacts are arranged at a distance from each other for receiving the stationary contact between the first and second contacts. The first contact is a straight contact blade for contacting stationary contacts at both ends of the blade. The second contact is a spring element configured to bend when the stationary contact is placed between the first contact and the second contact, and to cause a pressing force to the stationary contact to press the stationary contact against the first contact after the stationary contact has been placed between the first contact and the second contact.
