Definitions

  • the invention relates to an electromagnetic switching device with a switching position indicator which is actuated directly by the contact bridge support and which projects beyond the contour of the switching device at least in a switching position, the displacement of which is increased compared to that of the contact bridge support by means of a snap mechanism.
  • a switching position indicator is taken along by the contact bridge carrier when switched on, which is moved by a certain range after the path of the contact bridge carrier has ended via a spring-loaded slide which acts on an inclined plane. If the coil of the electromagnetic switching device is de-energized, the contact bridge carrier returns to the starting position and the contacts are opened, but the switch position indicator remains in the on position and must only be returned to the starting position by manual operation of the slide due to the weight of the switch position indicator. With this arrangement, only the on function but not the off function of the device can be displayed with certainty.
  • a switch position transmitter for electrical switches is also known (DE-B-1 590 211), in which a spring acts on a signaling switch shaft, which pulls it into the central position, and in which a coupling rod is slidably connected via stops to a pin attached to a pivoting lever is.
  • the invention is thus intended to provide a switching device of the type mentioned above, which additionally has the isolating function / DIN 57660, part 107 ⁇ 2.1.4), d. H. can take over the main switch function (DIN 57113 ⁇ 6.2) without having to make a considerable effort.
  • the switch position indicator with the contact bridge carrier is coupled with play in both the on and off direction so that both the opening and closing of the normally open contacts entrain the switch position indicator through the contact bridge carrier only when the contact bridge carrier has already covered a certain distance and that this distance is dimensioned when the normally open contacts are opened so that after they have been covered the contact opening distance fulfills the isolating function conditions.
  • a structurally simple structure for the connection with play results if the switch position indicator is displaceably guided with a T-shaped projection in a rectangular cutout of the contact bridge support which determines the play. It has proven to be advantageous if the snap mechanism is formed by means of a snap spring.
  • the switch position indicator comprises a pivotably mounted segment indicator.
  • the electromagnetic switching device shown in the drawing comprises a contact bridge support 1, which by the Druckbuchfe 2 is pressed into the off position of the switching device when the magnetic drive (not shown in more detail) is de-energized.
  • the contact pressure spring 3 presses the contact bridge 5, which is displaceably guided in the window 4 of the contact bridge carrier 1, onto the fixed contact parts 6. Further contact bridges can be held in the contact bridge carrier 1, as indicated by dashed lines, which can interact with other fixed contact parts.
  • the switch position indicator 7 is guided with a T-shaped projection 8 in a rectangular recess 9.
  • the rectangular recess 9 has a passage 10 for the stem 11 of the switch position indicator 7.
  • the walls 12 and 13 determine the play that the switch position indicator 7 has with respect to the contact bridge carrier 1. Due to its snap behavior, a spring 14 supported on the housing ensures the increased movement path of the switch position indicator 7 with respect to the contact bridge carrier 1.
  • the movement limitation is determined by a molding 15 which cooperate with the stops 16 and 17 of the cover 18.
  • An opening 19 is used to hang a padlock in order to be able to lock the switching device in the off position.
  • the switch position indicator 7 is only taken along when the contact bridge support 1 has covered the path 20. In this case, the creepage distances and clearances between the fixed contact parts 6 and the contact bridge 5 are so large that the isolating function is fulfilled. Due to the contact of the T-shaped extension 8 on the wall 13, the spring 14 is brought over the dead center position when the contact bridge support 1 moves further and the indicator jumps beyond the upper edge of the cover 18 until either the projection 15 abuts the stop 16 (this is the Normal case) or in the event that the separation did not take place completely, the T-shaped attachment 8 can be arranged on the wall 12, so that there is no defined display of the off state to the outside. By engaging the T-shaped extension 8 on the wall 12, the switch position indicator is pulled into the position shown in FIG.
  • the switching on of the contactor can be blocked by hanging a lock in the passage 10, i. H. it is ensured that, for. B. while the maintenance work on the machine, the switching device can be switched on neither mechanically nor electrically.
  • auxiliary control contacts 21 are additionally provided, which can be actuated by the molding 15 of the switch position indicator 7. This enables the disconnector function to be monitored.
  • upstream circuit breakers or the like take over the disconnector function when the contactor fails. The control then takes place via the auxiliary control contacts 21 with an additional time delay.
  • the auxiliary switches usual for motor contactors are not suitable for such a monitoring function.
  • the position is identified by 0 with I by the pivotably mounted segment indicator 22, which is pivoted by the switch position indicator 7.
  • the described switchgear design ensures galvanic isolation in safety circuits with little effort.
  • the switching device design described is becoming increasingly important due to the increasing use of electronic circuits, since electronic switching elements generally cannot meet the electrical isolation.
