Abstract (en)
[origin: EP2416332A1] The device has a rotary contact with switching pieces (400) that carry two end contacts (410), where the switching pieces are mounted in spatial variable rotary points. The rotary points include guide and pivot levers (210, 220), which are engaged with spatially fixed axles of guide and pivot lever bearings (215, 225) at a housing and with spatially movable axles (216, 226) of the levers at the switching pieces. Contact force springs i.e. tension springs, apply contact pressure force. An electric arc extinguishing chamber (600) is continuously formed over an opening path of contact pieces.
