It further includes fixed switching contacts and a device for cooling, de-ionizing and extinguishing an electric switching arc. The fixed contact is provided with a pre-contact function over the entire contact width thereof. Moveable contact levers are arranged according to a set pattern in a distributed manner over the entire width of the contact carriers and are provided with or without a pre-contact. A contact lever with a pre-contact and a contact lever without a pre-contact can be provided successively. Similarly, two or more contact levers with a pre-contact and two or more contact levers without a pre-contact can be successively and alternatingly provided in packet-form.
