  • the housing 3 of the switch has one cylindrical or conical section and coaxial to the axis 5 3b, which is dimensioned so that the cylindrical Switching means 4 through the housing opening on the front 3a can be inserted.
  • the housing 3 is also so trained that there are known means on the front panel 2 of the control element can be mounted. It will therefore not dealt with in more detail below on these assembly means.
  • At the front of the front panel 2 is one on the housing 3 adjacent, arch-shaped, stationary stop rib 8 arranged, which has a length of ⁇ / 2 measured in radians.
  • knob 6 shown has a substantially cylindrical or conical wall section with a free End of the cylindrical or conical wall section protruding and facing in the assembled state of the front panel 2 arcuate rib 9.
  • This rib 9 has an arc length ⁇ and is dimensioned and with regard to the insertion position the key 7 arranged that the stop rib 8 and the rib 9 together when turning the rotary knob 6 toast before turning the key 7.
  • the latter has a rotation angle in the illustrated embodiment of a maximum of 90 °.
  • the rotary switch 1 is thus designed that the rotary knob 6 from that shown in FIG Turn clockwise 90 ° to the right and can be turned back again.
  • the rotary switch 1 is for example as an electrical on / off switch applicable.
  • stop rib 8 and only touch the rib 9 when they alternate engage in corresponding recesses, if so the stop rib 8 into the recess delimited by the rib 9 6a of the free end of the cylindrical or conical Knob wall section engages.
  • the fixed stop rib 8 of the invention Overturn protection can be as shown in Figure 1 the front of the front panel 2 arranged, for example welded, glued or otherwise insoluble on this be attached.
  • the stop rib 8 can within the scope of the invention also on the housing 3 containing the switching means 4 or - as already mentioned above - on a lock washer be provided, which in turn on the front panel Control panel is arranged.
  • the latter variant has the essential one Advantage that the overturn protection according to the invention, in turn consisting of on the rotary knob and on the locking washer arranged, abuttable ribs, without big effort adapted to known rotary switches or even subsequently mounted on rotary switches already installed can be. So you can easily use standard rotary switches equipped with the overturn protection according to the invention in a first step the locking washer placed on the front panel and then on this the switch housing is attached, for example, by a nut can happen that is on a on the switch housing attached thread is screwed.
  • FIGS. 4 drawn to 9. They are as a whole with 10, 110, 210, 310, Designated 410 and 510 and each have one as a stop for the rib of the associated knob certain stop rib 11, 111, 211, 311, 411 and 511.
  • the discs also have one each radially inward protrusion 12, 112, 212, 312, 412 and 512 on, which in the inserted state in a recess of the Intervening housing and thus an undesirable as protection against rotation Prevents the disc from twisting.
  • a standard knob is used, which is an arcuate Has stop rib with arc length ⁇ / 2.
  • a standard knob is used, which is an arcuate Has stop rib with arc length ⁇ / 2.
  • FIGS. 10 and 15 Examples of key switches where the fixed Stop rib on the housing containing the switching means is provided, are shown in Figures 10 and 15.
  • the two rotary switches shown in these figures 601 and 701 are essentially identical, like switch 1 and each have a switch housing 603, 703 with a rotatable switching means arranged therein 604, 704, and a cap-shaped rotary knob 606, 706 with a key matching the slot in the switching device 607, 707.
  • the key switch shown in Figures 10 and 15 601 and 701 are also designed as three-way switches, for which two different authorization keys belong. We pass one of these two authorization keys those already described and shown in FIGS Sectional rotary knob 606 and 706 formed, the other by the one drawn in section in FIGS. 13 and 18 Knob 606b or 706b.
  • Switch 601 is a three-way switch with the three fixed ones Switch positions I, ⁇ , II.
  • the stop rib 608 of the housing 603 a length of ⁇ / 2 measured in radians
  • the knob 606b a rib with the length ⁇ From the drawing it is now clear that the two Knobs 606 and 606b in the attached state due to their different rib structure different switching authorizations allow.
  • Switch 701 is also a three-way switch, however this has two fixed switching positions I and ⁇ with an intermediate angle of 90 ° and a pulse circuit II with a rotation angle of 60 °.
  • this case has the housing 703 two narrow stop ribs 608. These are arranged in this way and dimensioned that the two knobs 706 and 706b with their ribs 709 and 709b of ⁇ / 2 and 5 ⁇ / 6 length in plugged-in state allow the circuits according to FIG. 19, where A is the switching options of the rotary knob 706 and B shows the circuit for knob 706b. From the figure 19 it can be seen that only with the rotary knob 706 the pulse switching II is possible and that the rotary knob 606b only the I- ⁇ rotary switch allows.
  • the knob 706b matching the switch 701 still has additionally one opposite the stop rib 709b Locking rib 710b.
  • This is used here of the rotary knob 706b on a switching element which, for example to prevent the type drawn in Figures 10 and 11. So is the rib in the illustrated embodiment 710b arranged so that when trying to turn the knob 706b put on the housing 603 of the switch 601, the ribs 608 and 710b butt and thereby inserting the Prevent key in the switching means 604.
  • the knob fits 706 to switch 601 and key 706 to Switch 601.
  • the knobs according to the invention can therefore optionally be designed so that they are not just special Allow circuits, but only additionally fit a switch or can be combined with several switches are.
  • the front panel can also be designed differently than in shown example. So of course she has to not necessarily part of the casing or housing the item to which the switch is attached should be, but can be as with conventional control panels an intermediate piece that can be screwed on, for example. It can also be manufactured, for example, so that the Rotary switch is recessed and its surface, for example connects flush to the surface of the front panel, whereby then the key of the rotary knob a correspondingly longer one Has form and protrudes from it.
  • the rotation protection of the disks 10, 110, 210, 310, 410 and 510 may be formed by means of themselves from that described above and in FIGS. 4 to 9 differentiate drawn type and for example by locking means are formed, which in turn consist of one in each Disc existing recess and a matching one as well Ribs located on the front panel or switch housing consist.
  • the washers can also be used as protection against rotation Have positioning pins or the like, which are used in the Engage the condition in a recess in the front panel and thus prevents undesired rotation of the disk.
