  • the the coupling length is set using the lock nut 54 fixed.
  • the auxiliary levers 32, 33 of an interrupter unit are set such that they are at right angles to the oscillating link 27 in the end positions corresponding to the switch-off or switch-on position and assume a dead center position.
  • the angles which in this case include the auxiliary levers 32, 33 with a plane C perpendicular to the plane B in the end positions are denoted by ⁇ 4 and ⁇ 4 . Since the pivot axis of the auxiliary levers 32, 33 and the axis of the shaft 20 also lie in the plane C, the angle ⁇ 4 is equal to the negative angle ⁇ 4 .
  • the auxiliary levers 32, 33 of the interrupter unit 3 are set via the drive linkage 47 such that they assume a smaller angle ⁇ 3 in comparison with the angle ⁇ 4 of the auxiliary levers 32, 33 of the interrupter unit 4 in the switch-off position according to FIG. 1, in the switch-on position 3, however, include a larger angle ⁇ 3 with the plane C.
  • the reverse is the selected setting of the auxiliary levers 32, 33 in the interrupter unit 2; 1 at a larger angle ⁇ 2 than those of the interrupter unit 4 (angle ⁇ 4 ), in the switched-on position according to FIG. 3 the angle ⁇ 2 is smaller than the angle ⁇ 4 .

  • the movable contact pieces 10 of the interrupter units 2, 3, 4 are staggered in terms of time out of engagement with the fixed contact pieces 8, ie they stagger a stroke KT necessary for the contact separation;
  • the contact separation on the interrupter unit 2 takes place, since the articulation point of the drive linkage 47 on the oscillating link 27 according to FIG. 3 is closest to the shaft 20, and thus already with a relatively small movement of the auxiliary levers 32, 33 Swiveling of the oscillating link 27 and thus also the swing arm 21 operatively connected to the push rod 22 takes place.
  • FIG. 4 Another embodiment of a likewise three-pole High-voltage switch 1 'is shown in Figs. 4 to 6.
  • the similar and equivalent parts are still with the same reference numerals as in Figs. 1 to 3.
  • Swing members 27 are the same as those 1 to 3 and form together with the above-mentioned transmission links each have a part a transmission chain assigned to each interrupter unit 2, 3, 4 60, which also in this embodiment with the continuously adjustable drive linkage 47 is connected.
