A switch apparatus includes at least two contact levers, arranged rotatably about a common rotation axis and arranged, at least sectionally, parallel to one another and spaced apart. The contact levers each have two contact lever arms including contact sections for respectively making contact with one fixed mating contact section of a power line element. The two first contact lever arms make contact with a first force transfer element, and the two second contact lever arms make contact with a second force transfer element for applying a spring force. At least one force transfer element has, in touching sections for touching the contact lever arms, a bulge which extends radially outwards, for the uniform transfer of the spring force to the contact lever arms. At least one holding element of the two holding elements may be configured to be movable relative to the power line elements via an articulated bearing.
