  • the second driver 12 is moved completely out of the slot 8 upon reaching the switch-on position of the first and second switching contact piece 2, 3 ( FIG. 5 ). Now, the pendulum moving part 7 by the securing device 17 in a second end position of the pendulum moving part 7 (if necessary, supported by the biased energy storage 13) is held.
  • a turn-off movement is shown.
  • the linear drive 9 drives the storage loading lever 10 counterclockwise, whereby the second driver 12 is moved into the slot 8.
  • the pendulum moving part 7 is held spring-loaded by the securing device 17.
  • the bolt 16 is driven through the gate 8 until the time in which the energy storage 13 with the storage spring 14 in the charged state, a dead center ( FIG.
  • the bolt 16 has been released from the second driver 12 and strikes against the second end stop 19 and is about to move the pendulum moving part 7 counterclockwise opposite and about to trigger a movement of the transmission shaft 6.
  • the FIG. 9 shows the jump-like displacement of the pendulum moving part 7 and a corresponding abrupt turn-off of relatively movable switching contact pieces 2, 3.
  • the linear actuator 9 pushes the first driver 11 out of the backdrop 8, so that a backup of the end position of the pendulum moving part 7 below Use of the force effect of the securing device 17 is present.
