  • the control device has brought the electrical equipment in a closed position.
  • the position of the position indicator 26 given by the position of the control shaft 4 of the contacts of the bulb, is such that the feeler 28 is retracted under the first interlocking lever 7, and does not interfere with the latch 29, which is biased by the spring towards the first interlocking lever 7.
  • the first interlocking lever 7 is supported on the stud 27 of the indicator 26, so that the flap 11 can not be brought opposite the access port 12 to the control shaft 3 of the control of the bulb via this lever 7.
  • the control device has brought the electrical equipment into an open position, the selector S of control of the grounding having not yet been actuated, so that the orifice 6 of access to the shaft of operation 5 of the earth shaft is closed by the flap 9 of the second interlocking lever 8.
  • the access port 12 to the operating shaft 3 of the control shaft 4 contacts of the switchgear is released and thus allows a closing maneuver.
  • the operating shaft of the control of the bulbs has achieved at least 70% of its opening rotational stroke, so that the probe 28 has moved the latch 29 in rotation clockwise against the return spring , showing a game j between the bent part 17 and the latch 29.
  • this clearance j allows the first interlocking lever 7 to be moved in rotation in the clockwise direction following an actuation of the position selector S to the position allowing the earthing , position illustrated on the figure 4 .
  • the selector S slides relative to the support of the apparatus, this sliding being guided by the displacement of the stud 27 in the arcuate groove 21 of the support of the apparatus.
  • the second interlocking lever 8 moves in rotation in the counterclockwise direction so as to release the access 6 to the operating shaft 5 of the grounding shaft.
  • the displacement of the selector S to the right in the drawings, corresponding to an authorization of earthing, can be carried out indifferently by the actuation of the actuator 22 of the selector S by the user, or by the actuation of the lock 23 by means of a key such as this is illustrated on the figure 4 .
  • the probe 28 remains retracted and does not act on the latch 29, which remains supported by its upper portion 29a on the first portion 18 of the bent portion 17 of the second arm 13 of the first interlocking lever 17 , as was the case on the figure 2 which illustrates the apparatus in closed position.
  • the latch 29 prevents the rotation of the second lever 8 and therefore the action on the selector S and thus on the lock 23. It is therefore no longer the stud 27 of the indicator 26 which blocks the selector S, a set i being created between this pad 27 and the first lever 7, but the latch 29 acting on the bent portion 17.
  • This latch 29 also prevents the displacement of the first lever 7 and thus prevents the locking of the control device in the open position, since the lever 7 can not close the orifice 12 for access to the primary shaft 3, the latter remaining therefore accessible for a closing maneuver.
  • the clearance present between the stud 27 and the lever 7 makes it possible to rotate the lever in the event of soldered contacts. This possibility of rotation makes it possible to force the prohibition of access to grounding.
  • the present invention thus prevents grounding of the cables if the circuit is soldered, the cables being always connected to the network, this being likely to cause a short circuit.
  • the invention therefore protects the user when it intends to put the cables to the ground, following a voluntary opening of the circuit breaker or switch to intervene thereon.
