  • Such a flexible display flag is inexpensive due to a plastic or elastomer film is formed.
  • the switch position indicator is preferably at one Switching device used, the switching drive one by one Includes pivot axis pivotally mounted shift lever.
  • This Shift lever is conveniently used to shift the Display flag shared by a fastening end of the display flag fixed to the gear lever at a distance from the axis of rotation is.
  • the display lever has a reference to the Axis centered, cylindrical rotating body on the enables a stable pivot bearing of the shift lever and also a good one regardless of the gear lever position Protection against tampering.
  • this rotating body is also used to guide the indicator flag, by being fixed to the circumference of the rotating body.
  • the indicator flag is breaking out into the interior of the housing preferably prevented by at least one housing web, which is approximately tangent to the rotary body of the shift lever is arranged.
  • a simple and stable attachment of the display flag to the Switch drive is by a retaining bead at the end of the attachment the display flag realized, the form-fitting in a corresponding Retaining groove of the switching drive, in particular the Shift lever.
  • the display flag is preferably with two display fields provided, for example, by different colors are marked, with the indicator flag between two display positions can be moved, each in each an associated display field appears in the housing window.
  • the electrical switching device 1 shown in FIG 1 includes an insulating housing 2, of which only a half-shell in sections is shown. To look inside the To enable housing 2, the housing 2 is touch-proof final second half-shell not shown.
  • On the housing front wall 3 of the housing 2 is a shift lever 4 arranged for manual actuation of the switching device 1.
  • the Housing front wall 3 is the one in the installed state User-facing side of the housing 2.
  • the shift lever 4 comprises a cylindrical rotating body 5 which is about its cylinder axis or axis of rotation 6 rotatably mounted in the housing 2 is and the circumference of the inside of a housing opening 7 of Front wall 3 is present.
  • FIG 2 includes the shift lever 4 also has a handle 8 and an actuating arm 9.
  • the handle 8 and the actuating arm 9 are mutually at an obtuse angle to the circumference of the rotating body 5 integrally formed and protrude radially from there with respect to the Axis of rotation 6 from.
  • the shift lever 4 is in the housing 2 used that the handle 8 through the housing opening 7 protrudes the housing 2 while the actuating arm 9 within of the housing 2 is arranged.
  • a switch position indicator 10 is in the Housing front wall 3 introduced a housing window 11 behind which a display flag 12 is slidably guided.
  • Guide for the indicator flag 12 is used within the housing 2 arranged guide web 13, which is at a short distance runs approximately parallel to the front wall 3 of the housing. Between the housing front wall 3 and the guide web 13 is thus a band-like guide channel 14 for the display flag 12 formed.
  • the display flag 12 which can be seen in FIG. 1 only hinted at is shown in more detail in FIG. She assigns one band-like shape and is made of a flexible material, in particular a plastic or elastomer film.
  • the display flag 12 is in its longitudinal direction 15 in two display fields 16a and 16b divided, for example one wear different color markings. That the display panel 16a adjacent longitudinal end of the indicator flag 12 is as a fastening end 17 provided and is used to attach the display flag 12 on the shift lever 4.
  • the fastening end carries 17 a retaining bead 18 which is positive in a corresponding holding groove 19 at the foot of the actuating arm 9 of the shift lever 4, and thus on the circumference of the rotating body 5, can be inserted.
  • the holding groove 19 extends not over the entire width of the shift lever 4, but is closed at one end by a stop wall 20.
  • the holding bead 18 faces one another a side edge 21 set back end, which as Stop surface 22 when inserting the display flag 12 in the holding groove 19 is used.
  • the stop surface 22 and the stop wall 20 are dimensioned so that when completely in the retaining groove 19 inserted retaining bead 18 the indicator flag 12 and the shift lever 4 to each other in the direction of the axis of rotation 6 are centered.
  • FIG. 4 shows the housing 2 with the shift lever 4 removed shown.
  • An extension of the guide web 13 is another Housing web 23 with reduced compared to the guide web 13 Strength arranged. Starting from the guide bridge 13 The housing web 23 extends approximately at a 45 ° angle from the Housing front wall 3 away, so that the housing web 23 the guide channel 14 widens approximately like a funnel towards the axis of rotation 6.
  • An identically trained and fully assembled state the housing web 23 opposite in mirror image second housing web is in the, not shown second half shell of the housing 2.
