Definitions

  • the switching device 1 described can thus have a compact design, with a small number of necessary parts.
  • FIGS. 3 through 13 show details of the switching device 1 described.
  • the connecting rod 10 is preferably designed as a plastic component and has, according to the present preferable execution configuration, two arms, which run from the support point to the engagement area 12, thus spanning over a gap.
  • the connecting rod 10 further comprises an actuating shoulder 29, with the actuating shoulder 29 bearing against the second projection 30 of the hand switching lever 7 when the hand switching lever 7 is in a non-stationary position in which the movable contact 4 and the housing-mounted contact 6 are in contact or almost in contact.
  • the actuating shoulder 29 can best be seen in Fig. 10 to 13 .
  • the actuating shoulder 29 is arranged on the connecting rod 10 between the end portion 12 of the connecting rod 10 and the movably mounting of the connecting rod 10.
  • the end portion 12 of the connecting rod 10 has a concave engagement area 31 for engaging at the first projection 11 of the hand switching lever 7. It is preferable that the first projection 11 have a recess, in order to avoid premature displacement of the connecting rod 10.
  • the contact separation occurs in a representative switching device 1, in which the latching is released.
  • the switching lever 7 is moved back into the switched-off position, the latch 20 is shifted again under the latch support 22, creating a new latching, which is necessary to keep the contacts 4, 6 connected.
  • the housing 14 of the switching device 1 have a - not shown - housing projection in the area of the latch support 22, and that the connecting rod 10 - particularly in the area of its placement on the latch support 22 - have a striking pad 16 for propping up the latch support 22 on the housing projection after the release of the latching.
  • the first projection 11 cannot push the connecting rod 10 - and, with it, the latch support 22 - too far from the latch 20. It can, therefore, be ensured that, when the switching lever 7 is moved back into the switched-off position, the latch 20 again forms a latching with the latch support 22.
