Abstract:
The present invention relates to a switching device comprising at least one contact point, an arc extinguishing chamber assigned to the contact point, and an arc blow device assigned to the contact point. The arc extinguishing chamber comprises an exit opening through which plasma, which is generated inside the switching device by a switch arc developing when the contact point opens, can exit out of the switching device, the exit opening having a clearance dimension and defining an exit plane. The arc blow device is provided for generating a magnetic blow field by which the switch arc developing when the contact point opens is blown away from the contact point towards the exit opening. Furthermore, the switching device comprises at least one first arc guide plate which extends from the contact point to the exit opening and by which the switch arc is guided and stretched on the way from the contact point to the exit opening, wherein the first arc guide plate comprises a first portion and a second portion within the arc extinguishing chamber between the contact point and the exit plane, the first portion of the first arc guide plate being arranged proximal to the contact point, and the second portion of the first arc guide plate being arranged distal to the contact point. According to the invention it is provided that the second portion of the first arc guide plate extends beyond the exit opening in a direction parallel to the exit plane so that the switch arc is stretched by the second portion of the first arc guide plate at least at one end of the switch arc beyond the clearance dimension of the exit opening, wherein an arc guide pin projecting from the second portion of the first arc guide plate is arranged in front of the exit opening, by which arc guide pin the switch arc is again shortened in front of the exit opening.

Claim (Index 10):
Switching device ( 1 ) according to  claim 1 , characterized in that the switching device ( 1 ) further comprises a second arc guide plate ( 19 ), wherein first and second arc guide plates ( 8 ,  19 ) diverge starting from the contact point ( 2 ) in such a way that the switch arc ( 4 .  4 \u2032,  4 \u2033,  4 \u2033) is first stretched to a length which lies above the clearance dimension ( 5 ) of the exit opening ( 3 ), wherein the switch arc ( 4 ,  4 \u2032,  4 \u2033) is shortened again in front of the exit opening ( 3 ) as a result of the arc guide pin ( 12 ).
