  • the switch position indicator a pivoted display lever with a display panel, which in at least one position of the Indicator lever visible from the outside through a housing window is.
  • a drive part of the display lever acts in this way together with the switching wheel of a step switch that the Drive part in a clearly assignable to the operating state Radius is held by the axis of rotation of the ratchet.
  • Such a display lever is a simple one, in particular very few parts comprehensive mechanics for displaying the Operating state realized.
  • the indicator lever is driven by the ratchet is connected, which is often anyway with a stepper is available.
  • the invention is one introduced into an end face of the ratchet wheel Link guide provided, in which a guide pin of the display lever protrudes as a drive part.
  • Prefers is this backdrop guide by a closed ring Guide groove formed.
  • a star-like or polygonal shape of the backdrop guide is particularly advantageous, especially since the distance between the axis of rotation of the ratchet wheel and the point of engagement of the drive part in the link guide during a rotation of the ratchet wheel is continuously varied.
  • By rounded Corners of the star or polygon shape is a low-friction and tilt-free guidance of the drive part is ensured.
  • the indicator lever is used to simplify the assembly effort preferably carried out in one piece.
  • plastic especially polyoxymethylene (POM) or polyamide (PA) as material for the Display lever particularly suitable. This is especially the Manufacture of the indicator lever as an inexpensive molded part allows.
  • the electrical shown in FIG 1 with the housing 1 open Switchgear 2 has two input terminals 3a, 3b and two output terminals 4a, 4b and a magnetic step switch 5 for remote-controlled triggering of a switching process Mistake.
  • the step switch 5 comprises a magnetic coil 6 and one arranged at a head end 7 of the magnetic coil 6 Yoke plate 8.
  • the yoke plate 8 is shown in FIG shown rest position at a short distance from the head end 7 suspended in such a way that they are projected along the Coil axis 9 approximately covers the cross section of the magnetic coil 6.
  • the yoke plate 8 is on a side edge 10 pivoted, so that they towards the head end 7 or is pivotable away from this.
  • the side edge 10 opposite Free end 11 is a slide-like projection formed with an approximately parallel to the coil axis 9 extending slide valve 12 with respect to an approximately Direction of force along the coil axis 9 in a positive manner Connection is established.
  • a coil spring mounted on the slide valve 12 13 holds the slide switch 12 and with it connected yoke plate 8 under tension in the illustrated Rest.
  • the slide switch 12 projects with a button end 14 for manual Actuation of the switching device 2 out of the housing 1.
  • the opposite end 15 lies approximately on the circumference of a - Put simply, square ratchet wheels 16.
  • switching device 2 When switching device 2 is operated, be it by manual Pushing the button end 14 or by applying an electrical
  • the yoke plate 8 becomes voltage to the magnetic coil 6 attracted to the head end 7 by magnetic force and the slide switch 12 parallel to the coil axis 9 in the direction of the switching wheel 16 moves.
  • the end 15 of the Switch slide 12 a torque on the switching wheel 16 and turns it one-eighth of a turn with each shift (45 °) in a predetermined direction of rotation 17 (in the illustrated Example clockwise).
  • the switching wheel 16 is in a manner not shown with a switch contact 18th in mechanical connection, so that when the Switching wheels 16 of the switching contact 18 between two switching positions is switched back and forth.
  • the switching device 2 has a switch position indicator 19 provided, the main component of which is a display lever 20.
  • the Indicator lever 20 is approximately parallel to the slide switch 12 in Housing 1 positioned and about a to the axis of rotation 21 of the Ratchets 16 approximately parallel pivot axis 22 on the housing 1st pivoted.
  • the display lever 20 from a display arm 23 and a drive arm 24 formed from approximately opposite sides each approximately perpendicular to the pivot axis 22 on a joint sleeve 25 are molded.
  • the indicator lever 20 is positioned in the housing 1 such that the display field 27 serving free end of the display arm 23 near one User accessible housing front 28 lies and through a housing window let into the housing front side 28 29 is visible to the outside.
  • the free end of the drive arm 24 is with a guide pin 30 acting as a drive part provided, approximately in the direction of the pivot axis 22 from the drive arm 24 stands out.
  • the guide pin 30 forms together with one in FIG 3 illustrated guide of the switching wheel 16 a Swivel drive for the indicator lever 20.
  • the link guide is designed as a ring-shaped closed guide groove 31, which is introduced into an end face 32 of the switching wheel 16 and whose axis of rotation 21 rotates in an axially symmetrical manner.
  • the guide groove 31 has the shape of a square with the axis of rotation 21 curved side lines, i.e. a hybrid form between a regular polygon and an asterisk.
