Embodiment; -ig. 10: a view of the movable switch plate (simplified illustration) from the side of the cover plate, according to the embodiment according to FIGS. 1 and 2.

In Fig. 1 and 2, a switch with four switch positions (S ₀ - S ₃ ) is shown. This consists of a cover plate 1 with recess 2, the fixed switch plate 3 and the movable switch plate 4, the contact surfaces in the form of spring contacts 5 and contact tracks 6 have. The movable switch plate 4 is provided with two guide pins 7.8, which are guided in a respective guideway 9.10. The guideway 9 is formed by straight web segments 11, which are lined up at the same angle and a closed guideway 9, ie guideway beginning and end are directly connected to each other result. The guideway 10 is formed as a consisting of a straight track segment 11 lane and as an open track, ie no direct connection between the guideway beginning and end, designed babei the guideway 9 for the guide pin 7 in the switch interior by a guide edge 14 of a square, with the fixed switch plate connected guide piece 12 and the cover plate side formed by a further guide edge 14. In contrast, the guide track 10 for the guide pin 8 consists of a straight, arranged in the fixed switch plate 3 guide slot 13 lying in a plane parallel guide edges 14. On the guide pin 7, the actuating element 15 is further provided, and the guide piece 12 is for locking the respective switch position equipped with a locking element 16 not further described.

Now, if the seated on the guide pin 7 actuator 15 is moved from its basic position S ₀ in the arrow direction in the position S ₁ , the guide pin 7 moves along the guide flanks 14 of the guide piece 12 and the cover plate 1 of the first straight path segment 11. Simultaneously shifts also guided in the guide contactor 13 guide pin 8 to the right. In this case, the movable switch plate 4 is not only shifted to the right with respect to the fixed switch plate 3, but also performs a rotation superimposed on the straight movement (and thus surface movement) about the guide pin 8 acting as a displaceable axis. The located on the switch plate 4 contact paths 6 thereby occupy a different position relative to the located on the switch plate 3 spring contacts. If the actuator from the switch position S ₁ in the arrow direction further pushed to the bottom right, the switch position S _{2 is} reached. In this way, mutatis mutandis, the other switch positions can be adjusted clockwise or counterclockwise.

Another embodiment of the switch is shown in Figure 3. In contrast to the variant described in FIGS. 1 and 2 in this case both guideways 9,10 are formed as open guideways, which consist of similar zigzag-shaped, lined up at equal angles straight track segments 11. The guideways 9,10 are provided in the fixed switch plate 3 as a guide slot or guide groove and / or in the cover plate as a guide slot. The actuating element 15 is connected directly to the movable switch plate 4 and arranged between the two .Führungsstiften 7.8 and extends through (not shown) located in the cover plate 1 recess. When shifting the

Actuating element 15 in the arrow direction is in each case a parallel guide of the guide pins 7,8 guaranteed and carried out a planar displacement of the switch plate 4 relative to the switch plate 3 without superimposed rotation. In the example of FIG. 4, the guideways 9,10, in contrast to FIGS. 1 and 2, both open. These consist of juxtaposed, curved track segments 11, wherein the arranged as a guide slot 13, arranged in the fixed switch plate 3 guideways 9,10 connected at the point of switch position S ₃ and arranged in mirror image to the longitudinal axis 17. The actuator 15 is connected directly to the movable switch plate 4 and undergoes a coordinated with the guideways 9,10 guide 18 - shown in phantom - in the cover plate, not shown. In this case, the guide 18 is formed as a guide slot 13.

If the actuating element 15 is displaced from the basic position B ₀ in the direction of the arrow, the guide pin 8 forms the axis of rotation, and the guide pin 7 moves from the switch position S ₀ into the switch position S ₁ . The actuating element 15 is thus in position B ₁ . If it is moved further in the direction of the arrow, the guide pin 7 located in position S ₁ forms the axis of rotation, and the guide pin 8 moves into switch position S ₂ , wherein the actuating element 15 assumes the position B ₂ . Upon further actuation of the element 15 in the direction of arrow again the guide pin 8 forms the axis of rotation, and the guide pin 7 goes into the switch position S ₃ , while the actuator 15 assumes the position B ₃ . In the last possibility of actuation of the element 15 by moving from position B ₃ to position B ₄ , the guide pin 7, now in position S _3, again acts as an axis of rotation, and the pin 8 assumes the position S ₄ . Contrary to the direction of the arrow, the actuating element 15 and the guide pins 7, 8 are analogously returned to their respective initial position B ₀ , S ₀ and S ₃ . The paths of the actuating element 15 shown in FIG. 4 at the same time demonstrate the paths which the contact tracks 6 located on the movable switch plate 4 pass through relative to the spring contacts 5 arranged on the fixed switch plate 3.

In Fig. 5, an embodiment is disclosed, the guideways 9,10 are united in a closed, common guideway with dual function, ie arranged in the fixed switch plate 3 closed guideway guides both the guide pin 7 and the guide pin 8. The guideway is doing is formed of three curved track segments 11, which have the same radius of curvature and the same arc length and are thus arranged symmetrically to the axes 17. The actuator 15 is connected to the movable switch plate 4 and undergoes a matched with the guideway guide 18 on the star-shaped recess 2 (shown in phantom) in the cover plate, not shown. By such a design and the movement of the actuating element 15 in the positions B ₀ -B ₅ a total of 6 switch positions (S ₀ to S ₅ ) are possible, the rotational axis functions of the guide pins 7,8 change.

A next embodiment variant is shown in FIG. In this case, the guideway 9 and the guide pin 8, the guideway 10 associated with the guide pin 7. Both guideways 9,10 are provided in the fixed switch plate 3, designed as open guideways and consist of zig-zag-shaped curved curved track segments 11. The actuator 15 is connected to the movable switch plate 4 and undergoes a tuned with the guideways 9,10 Guide 18 with slots and recesses 2 (both shown by dashed lines) in the cover plate, not shown.

This training also with rotating axis function, as well as the examples of Figures 4 and 5, allows, according to the positions B ₀ -B _{9 of} the actuating element 15,10 switch positions, S ₀ -S ₉ , and is particularly advantageous when a device Turn on and off in a specific order, with locking relay or locking electronics is saved. This advantage applies to all described embodiments, which are provided with open guideways.

In Fig. 7, an embodiment is shown, which differs from that shown in FIGS. 1 and 2 by the arrangement of the formed as a guide slot 13 closed track 9 for the guide pin 7 in the fixed switch plate 3 and moreover a larger number of Switch positions (S ₀ -S ₈ ) allows, the guideway 9 consists of lined up in the same and different angles straight track segments 11. With regard to the basic mode of operation of this embodiment, reference is made to the functional description in FIGS. 1 and 2. Another variant of the switch shows Fig.8. It follows the illustrations according to FIGS. _1, 2 and 7, but allows more complicated switching possibilities with a larger number of switch positions (S ₀ -S ₁₅ ). In this case, the guide track 9 is formed as a closed guide track and provided as a guide groove 19 in the fixed switch plate 3. The guideway 9 consists of aligned in equal and different angles straight and curved track segments 11, which are partially connected with cross-linking web segments 20, in a curved or not shown straight form.

So can be taken from position switch S ₄ by a shift to the left above the position S ₃ , by a shift to the right above the position S ₅ , by a shift to the right position S ₈ or by shifting to the right with simultaneous rotation in a clockwise direction the position S ₉ while driving over the position S ₈ . By shifting to the left and down can be taken from position S _4, the position S ₁₃ , etc. From position S ₉ , it is possible to take over the position S _8, the positions S ₄ or S ₇ or the position S ₁₀ , etc. Furthermore, z. B. from S ₄ by passing over S ₁₃ , S ₁₄ and S ₁₅ to S _{0 are} returned, without overriding the positions S ₃ , S ₂ and S ₁ , so skip them.

In Fig. 9, the fixed switch plate 3 is shown with a possible contact arrangement for the embodiment of FIGS. 1 and 2 with four possible switch positions (S ₀ to S ₃ ). With K ₀ to K ₉ designed as spring contacts 5 contact surfaces are designated.

Fig. 10 shows the cooperating with the fixed switch plate 3 movable switch plate 4 (preferably printed circuit board material) with formed on the bottom as contact tracks 6 contact surfaces (shown in phantom) for the example of FIGS. 1 and 2. The contact tracks 6 are designed in that, for a part of the contacts K ₀ to K _9, no contact interruption occurs when switching from one switch position to the next. For the movable switch plate 4 of FIG. 10 following switch connections of the spring contacts 5 of the fixed switch plate 3 of FIG. 9 for the embodiment of FIGS. 1 and 2 (switch position S ₀ to S ₃ ) are produced: 1. switch position S ₀

The connection between K ₁ and K ₀ is interrupted (switch position "Off"). In this position the connection of the other contacts can be arbitrary.

2. Switch position S ₁

K ₁ , K ₅ and K ₀ connected K ₂ and K ₃ connected K ₄ open K ₆ open K ₈ and K ₇ connected K ₉ open

3. Switch position S ₂

K ₁ , K ₄ , K ₅ and K ₀ connected K ₂ open K ₃ open K ₆ open K ₈ open

K ₉ and K ₇ connected X. switch position S ₃ K ₁ , K ₄ and K ₀ connected K ₂ open K ₃ open K ₆ and K ₅ connected K ₇ open K ₉ and K ₇ connected

In addition, the following criteria are met:

On the way from switch position S ₂ to switch position S ₃ , the contacts K ₁ , K ₀ and K _{4 are} SO the contacts K ₉ and K _{7 are} not interrupted; in contrast, the contacts K ₂ and K ₃ and the contact K ₈ not closed.

In addition, it can be seen from the circuit connections that the contact K _{5 is} a changeover switch to contact K ₆ and the contacts <! or K ₀ and the contact K _{4 is} a simple switch to the contacts K ₁ and K ₀ . In this case, 2 contacts are saved over the known switches, since the corresponding compounds are produced by the design of the contact tracks 6 on the movable switch plate 4 of FIG.
