Abstract
The invention relates to a single- or multi-pole switching device, in particular for DC applications, having at least one rotating switching element () which is connected to a drive, and also comprising switching contacts (), connection pieces () and connection poles or connection terminals () and a housing arrangement which accommodates the abovementioned parts. According to the invention, a movably guided rotary cylinder () is formed in the housing arrangement, said rotary cylinder being located in a body which is designed as a rotary cylinder holder (). The rotary cylinder () has at least one contact pin () which passes radially or tangentially or eccentrically through the rotary cylinder and has, at its end, a contact piece () in each case. Mating contact pieces () are arranged in the rotary cylinder holder (), said mating contact pieces being electrically connected to the connection pieces () or connection poles or connection terminals (). A narrow, arc-influencing gap is present between the rotary cylinder () and the rotary cylinder holder (), wherein, as a result of the movement of the rotary cylinder (), the electrical connection between the contact pieces () and the mating contact pieces () can be broken by way of the contact pin () and the resulting disconnection arcs () enter the air gap subject to an extension and are rapidly extinguished there.
