Description

Die Erfindung betrifft einen Sicherheitsschalter mit den Merkmalen des Oberbegriffs des Anspruches 1.The invention relates to a safety switch with the features of The preamble of claim 1.

Sicherheitsschalter, wie sie beispielsweise aus der DE 44 08 024 A1 bekannt sind, dienen dazu, die Stromversorgung von elektrischen Maschinen davon abhängig zu machen, ob gewisse Schutzeinrichtungen der Maschine sich in der richtigen Stellung befinden. Bei einigen Anwendungen kann es vorkommen, daß der Sicherheitsschalter den Steuerstromkreis für die Stromversorgung der Maschine nicht schaltet, weil die Schutzeinrichtungen größere Toleranzen aufweisen als der Sicherheitsschalter zuläßt.Safety switch, as for example from DE 44 08 024 A1 are known, serve the power supply of electrical Make machines dependent on whether certain protective devices the machine is in the correct position. With some Applications it can happen that the safety switch Control circuit for the machine power supply does not switch because the protective devices have larger tolerances than the Allows safety switch.

Aus der DE 296 09 012 U1 ist ein Sicherheitsschalter gemäß dem Oberbegriff des Anspruchs 1 bekannt. Dabei werden die Mittel zum Fixieren der Steuerscheibe durch einen quer zur Längsachse des Schaltstößels bewegbaren und in einen Anfangsbereich des Aufnahmeschlitzes für den Betätiger eingreifenden elektromagnetisch betätigbaren Riegel blockiert. Nachteilig ist dabei, daß im entriegelten bzw. entfixierten Zustand die Steuerscheibe beispielsweise durch Vibrationen oder Erschütterungen derart bewegt werden kann, daß der Schlüssel bzw. Betätiger aus dem Schlüsselkanal herausbewegt wird.From DE 296 09 012 U1 a safety switch according to the The preamble of claim 1 is known. The means for Fixing the control disc by a transverse to the longitudinal axis of the Switch plunger movable and in an initial area of the Receiving slot for the actuator engaging electromagnetic actuatable latch blocked. The disadvantage here is that in the unlocked or the control disc is unlocked, for example by vibrations or vibrations can be moved in such a way that the key or Actuator is moved out of the key channel.

Der Erfindung liegt daher die Aufgabe zugrunde, einen verbesserten Sicherheitsschalter der eingangs genannten Art zu schaffen. Diese Aufgabe ist durch einen im Anspruch 1 bestimmten Sicherheitsschalter gelöst. Besondere Ausführungsarten der Erfindung sind in den Unteransprüchen bestimmt.The invention is therefore based on the object of an improved To create safety switches of the type mentioned. This task is solved by a safety switch defined in claim 1. Particular embodiments of the invention are in the subclaims certainly.

Durch die Mittel zum Fixieren der Steuerscheibe bei vollständig eingeführtem Schlüssel wird verhindert, daß die Steuerscheibe sich durch Erschütterungen der Maschine unter dem Schlüssel durchdreht, und dadurch der Schlüssel nicht mehr herausgezogen werden kann. Der eingeführte Schlüssel hat nach Beendigung der Drehbewegung der Steuerscheibe eine bestimmte Einführtiefe. Sofern die Mittel zum Fixieren ein tieferes Einführen des Schlüssels, also einen größeren "Nachlauf" ermöglichen, können auch nicht exakt schließende Schutzeinrichtungen zuverlässig überwacht werden. Es sind vorteilhafte Ausführungsformen vorgesehen, bei denen zumindest ein Teil dieser Mittel die Steuerscheibe auch bei nicht eingeführtem Schlüssel fixieren.By means of fixing the control disc when complete introduced key is prevented that the control disc through Machine shocks under the key, and the key can no longer be removed. The inserted key has the after the rotation of the Control disc a certain insertion depth. Unless the means to fix a deeper insertion of the key, ie a larger "wake" protective devices that do not close exactly be reliably monitored. They are advantageous embodiments provided, in which at least part of this means the control disc fix even if the key is not inserted.

Bei einer bevorzugten Ausführungsform sind die Mittel zum Fixieren dadurch verwirklicht, daß die Steuerscheibe wenigstens eine Ausnehmung aufweist, die mit einem relativ zur Steuerscheibe beweglichen Sperrelement zusammenwirkt.In a preferred embodiment, the means for fixing in that the control disk has at least one recess has that with a movable relative to the control disc locking element interacts.

Die Ausnehmung kann beispielsweise in einer seitlich an die Steuerscheibe angeformten Materialpartie vorgesehen sein, während das Sperrelement dann an einem seitlich von der Steuerscheibe angeordneten und relativ zu dieser beweglichen Verriegelungsglied ausgebildet ist. Bei diesen Ausführungen können Teile verwendet werden, die bereits bei bekannten Sicherheitsschaltern vorhanden sind. Dies reduziert die Zahl der notwendigen Teile und die erforderlichen Änderungen der Werkzeuge. Eine besonders raumsparende Ausführung ergibt sich, wenn das Verriegelungsglied senkrecht zur Drehachse der Steuerscheibe beweglich ist.The recess can, for example, in a laterally on the control disc molded material portion may be provided while the locking element then on a side of the control disc and relative to this movable locking member is formed. With these Designs can use parts that are already known Safety switches are available. This reduces the number of necessary parts and the necessary changes to the tools. A particularly space-saving design results if the locking member perpendicular to the axis of rotation of the control disc is mobile.

Ausnehmung und Sperrelement können beispielsweise aber auch so verwirklicht sein, daß die Ausnehmung in einem Bereich der Steuerscheibe vorgesehen ist, welche bei einer Drehung der Steuerscheibe in den Schlüsselkanal ragt, und daß das Sperrelement am Schlüssel vorgesehen ist. Bei einem längsgeschlitzten, gabelförmig ausgebildeten Schlüssel ergibt sich eine besonders einfache Verwirklichung des Sperrelementes durch auf der Innenseite des Schlitzes vorgesehene Absätze. Die Ausnehmung ist dann nutartig ausgebildet, wodurch die Steuerscheibe ihre Bruchsicherheit beibehält. Die Ausnehmung könnte aber auch die gesamte Dicke der Steuerscheibe durchsetzen, wobei dann am Schlüssel anstelle der Absätze eine durchgehende Materialpartie vorgesehen sein könnte.
Die Funktionsfähigkeit des Sicherheitsschalters wird vorzugsweise dadurch gefördert, daß die Mittel zum Fixieren symmetrisch auf beiden Seiten der Steuerscheibe vorgesehen sind.The recess and the locking element can, for example, also be implemented in such a way that the recess is provided in a region of the control disk which projects into the key channel when the control disk rotates, and that the locking element is provided on the key. In the case of a longitudinally slotted, fork-shaped key, the locking element is particularly simple to implement by means of shoulders provided on the inside of the slit. The recess is then groove-shaped, whereby the control disk maintains its break resistance. However, the recess could also penetrate the entire thickness of the control disk, in which case a continuous material section could be provided on the key instead of the shoulders.
The functionality of the safety switch is preferably promoted in that the means for fixing are provided symmetrically on both sides of the control disc.

Eine Erweiterung der Einsatzmöglichkeiten des erfindungsgemäßen Sicherheitsschalters ergibt sich, wenn dieser zwei, nicht parallel zueinander, vorzugsweise senkrecht zueinander verlaufende Schlüsselkanäle aufweist, in die wahlweise der Schlüssel eingeführt werden kann. Betätigungsglieder, welche bei nicht eingeführtem Schlüssel in die Schlüsselkanäle ragen und vorzugsweise mit Sperrgliedern zum Fixieren der Steuerscheibe in dieser Stellung verbunden sind, geben beim Einführen des Schlüssels die Steuerscheibe frei. Die Zahl der notwendigen Bauteile wird auf einfache Weise reduziert, wenn ein solches Betätigungsglied entlang einer Winkelhalbierenden der beiden Schlüsselkanäle beweglich ist und dadurch in beide Schlüsselkanäle gleichzeitig ragen kann. Eine weitere vorteilhafte Reduktion der Zahl der Bauteile wird erreicht, wenn das Betätigungsglied zugleich als Verriegelungsglied ausgebildet ist.An expansion of the possible uses of the invention Safety switch arises when this two, not in parallel to each other, preferably perpendicular to each other Has key channels into which the key can optionally be inserted can. Actuators which, when the key is not inserted, into the Key channels protrude and preferably with locking members for fixing the control disc are connected in this position, give when inserting the control disc free. The number of components required is reduced in a simple manner if such an actuator is movable along a bisector of the two key channels and can thus protrude into both key channels at the same time. Another advantageous reduction in the number of components is achieved if that Actuator is also designed as a locking member.

Bei dem ersten Ausführungsbeispiel des erfindungsgemäßen Sicherheitsschalters weist das Schaltergehäuse 1 in dem in der Zeichnung dargestellten Kopfteil einen in Längsrichtung des Schaltergehäuses 1 verlaufenden ersten Schlüsselkanal 3 auf. Ferner ist im Kopfteil des Schaltergehäuses 1 ein zweiter Schlüsselkanal 5 vorgesehen, welcher senkrecht zum ersten Schlüsselkanal 3 verläuft. Ein Schlüssel 7 ist von außen wahlweise in einen der beiden Schlüsselkanäle 3 oder 5 einführbar. Im Kopfteil des Schaltergehäuses 1 ist eine Steuerscheibe 9 drehbar gelagert, wobei deren Drehachse 11 sowohl senkrecht zum ersten Schlüsselkanal 3 als auch senkrecht zum zweiten Schlüsselkanal 5 verläuft. Die Steuerscheibe 9 ragt in beide Schlüsselkanäle 3 und 5 hinein.In the first embodiment of the invention Safety switch has the switch housing 1 in the in the drawing head part shown in the longitudinal direction of the switch housing 1st extending first key channel 3. Furthermore, in the head part of the Switch housing 1, a second key channel 5 is provided, which runs perpendicular to the first key channel 3. A key 7 is from outside insertable either in one of the two key channels 3 or 5. A control disk 9 is rotatable in the head part of the switch housing 1 stored, the axis of rotation 11 both perpendicular to the first Key channel 3 and perpendicular to the second key channel 5. The control disk 9 projects into both key channels 3 and 5.

An einer Stelle, die bei nicht eingeführtem Schlüssel 7 im Kreuzungsbereich der beiden Schlüsselkanäle 3 und 5 liegt, weist die Steuerscheibe 9 auf jeder Seite eine radial nach außen verlaufende, kurze Nut 13 auf. Der Schlüssel 7 ist an dem in einen Schlüsselkanal 3 oder 5 einzuführenden Ende gabelförmig ausgebildet, wobei auf der Innenseite der beiden Enden im Endbereich des Schlüssels 7 jeweils ein Quersteg 7' vorgesehen ist. Beim Einführen des Schlüssels 7 in einen der beiden Schlüsselkanäle 3 oder 5 greifen diese Querstege 7' in die Nuten 13 ein und nehmen dadurch die Steuerscheibe 9 im weiteren Verlauf des Einführvorganges des Schlüssels 7 mit, wodurch es zu einer Drehbewegung der Steuerscheibe 9 kommt.At a point that when the key is not inserted 7 in Crossing area of the two key channels 3 and 5, has the Control disc 9 on each side a radially outward, short Groove 13. The key 7 is on the key channel 3 or 5 inserted end fork-shaped, being on the inside of the both ends in the end region of the key 7 each have a cross bar 7 ' is provided. When inserting the key 7 into one of the two Key channels 3 or 5 engage these crossbars 7 'in the grooves 13 and thereby take the control disc 9 in the further course of Insertion process of the key 7, causing it to rotate the control disc 9 comes.

An der Steuerscheibe 9 liegt ein in der Zeichnung nicht dargestellter, in Längsrichtung des Schaltergehäuses verschiebbarer Stößel an. Am anderen Ende dieses Stößels ist im Schaltergehäuse 1 ein ebenfalls nicht dargestellter Schalter vorgesehen. Bei der durch das Einführen des Schlüssels 7 hervorgerufenen Drehbewegung der Steuerscheibe 9 verschiebt letztere den Stößel und betätigt dadurch zwangsläufig den Schalter.On the control disc 9 is a, not shown in the drawing, in Longitudinal direction of the switch housing sliding plunger. At the other The end of this plunger is also not in the switch housing 1 shown switch provided. With the by introducing the Key 7 caused rotation of the control disc 9th the latter moves the plunger and thereby inevitably actuates the Switch.

Auf den beiden Seiten der Steuerscheibe 9 ist im Bereich der Drehachse 11 jeweils eine ovale Materialpartie 15 angeformt. Jede der beiden gleich ausgebildeten Materialpartien 15 weist eine in Bezug auf die Drehachse 11 radial der Nut 13 gegenüberliegende, nutartige erste Ausnehmung 17 sowie zwei um 90□ versetzte, ebenfalls nutartig ausgebildete weitere Ausnehmungen 19 auf. Die weiteren Ausnehmungen 19 befinden sich an den beiden spitzen Enden der ovalen Materialpartie 15, während die erste Ausnehmung 17 an einer Längsseite vorgesehen ist.On the two sides of the control disk 9 is in the region of the axis of rotation 11 each formed an oval material section 15. Each of the two the same formed material parts 15 has one with respect to the axis of rotation 11 radially opposite the groove 13, groove-like first recess 17 and two more, offset by 90 □, also formed like a groove Recesses 19 on. The further recesses 19 are located the two pointed ends of the oval material section 15, while the first Recess 17 is provided on one long side.

In axialer Richtung neben den Materialpartien 15 der Steuerscheibe 9 ist auf beiden Seiten der Steuerscheibe jeweils ein Verriegelungsglied 21 vorgesehen. Jedes Verriegelungsglied 21 weist ein Langloch 23 auf, welches die Drehachse 11 umschließt. Durch in der Zeichung nicht dargestellte Führungen im Schaltergehäuse 1 ist die einzig mögliche Bewegungsrichtung des Verriegelungsgliedes 21 definiert, und zwar senkrecht zur Drehachse 11 und zugleich in Richtung des Langloches 23. Diese Bewegungsrichtung ist auf den Kreuzungspunkt der beiden Schlüsselkanäle 3 und 5 ausgerichtet und verläuft entlang einer ihrer Winkelhalbierenden, also um 45□ versetzt zu den Schlüsselkanälen. Das auf diesen Kreuzungspunkt ausgerichtete Ende des Verriegelungsgliedes 21 ist mit 21' bezeichnet. An dem bezüglich dieses Kreuzungspunktes abgewandten Ende ist das Verriegelungsglied 21 mittels einer in der Zeichnung nicht dargestellten Feder am Schaltergehäuse 1 abgestützt. Auf der der Steuerscheibe 9 zugewandten Seite weist das Verriegelungsglied 21 einen erhabenen Sperrzahn 25 auf, welcher formschlüssig sowohl in die erste Ausnehmung 17 als auch die weiteren Ausnehmungen 19 der Materialpartie 15 der Steuerscheibe 9 eingreifen kann. Die mögliche Eingreiftiefe ist dabei im Falle der weiteren Ausnehmungen 19 geringer als bei der ersten Ausnehmung 17. Das auf den Kreuzungspunkt der Schlüsselkanäle 3 und 5 ausgerichtet Ende 21' ragt sowohl in den ersten Schlüsselkanal 3 als auch in den zweiten Schlüsselkanal 5. Dieses Ende 21' des zugleich als Betätigungsglied wirkenden Verriegelungsgliedes 21 ist als Rampe für den Schlüssel 7 ausgebildet. In the axial direction next to the material parts 15 of the control disk 9 a locking member 21 on each side of the control disk intended. Each locking member 21 has an elongated hole 23, which encloses the axis of rotation 11. Not in the drawing guides shown in the switch housing 1 is the only possible Direction of movement of the locking member 21 defined, namely perpendicular to the axis of rotation 11 and at the same time in the direction of the elongated hole 23. This direction of movement is at the intersection of the two Key channels 3 and 5 aligned and running along one of them Bisectors, i.e. offset by 45 □ to the key channels. That on this crossing point is aligned end of the locking member 21 designated 21 '. At the one facing away from this crossing point End is the locking member 21 by means of one in the drawing Spring not shown supported on the switch housing 1. On the the Control disc 9 facing side, the locking member 21 has a raised ratchet tooth 25, which positively in both the first Recess 17 and the other recesses 19 of the Lot of material 15 of the control disk 9 can engage. The possible The depth of engagement is less than in the case of the further recesses 19 at the first recess 17. The on the intersection of the Key channels 3 and 5 aligned end 21 'protrudes both in the first Key channel 3 as well as in the second key channel 5. This end 21 ' the locking member 21, which also acts as an actuator, is as Ramp designed for key 7.

Solange der Schlüssel 7 sich außerhalb der Schlüsselkanäle 3 und 5 befindet, ist die Steuerscheibe 9 mit der Nut 13 auf den Kreuzungspunkt der beiden Schlüsselkanäle 3 und 5 ausgerichtet. Beim Verriegelungsglied 21 liegt aufgrund der das Verriegelungsglied 21 belastenden Federkraft die Drehachse 11 an demjenigen Ende des Langloches 23 an, das vom Kreuzungspunkt abgewandt ist. Gleichzeitig greift der Sperrzahn 25 in die Ausnehmung 17 der Materialpartie 15 ein.As long as the key 7 is outside the key channels 3 and 5 is, the control disc 9 with the groove 13 on the crossing point of the two key channels 3 and 5 aligned. With the locking element 21 lies due to the spring force loading the locking member 21 Axis of rotation 11 at that end of the elongated hole 23 on the Crossing point is turned away. At the same time, the ratchet tooth 25 engages in the Recess 17 of the material section 15.

Wird in einem der beiden Schlüsselkanäle 3 oder 5 der Schlüssel 7 eingeführt, so trifft der Schlüssel 7 zunächst gegen das als Rampe wirkende Ende 21' des Verriegelungsgliedes 21 und schiebt dadurch das Verriegelungsglied 21 entgegen der Federkraft zurück, also aus dem Schlüsselkanal 3 bzw. 5 heraus. Gleichzeitig löst sich der Sperrzahn 25 aus der ersten Ausnehmung 17. Beim weiteren Einführen des Schlüssels 7 nehmen dessen Querstege 7', welche in jeweils eine Nut 13 eingreift, die Steuerscheibe 9 mit. Gleichzeitig läuft die Materialpartie 15 mit ihrem Umfang am Sperrzahn 25 vorbei. Aufgrund der Exzentrizität der Materialpartie 15 wird das Verriegelungsglied 21 noch weiter aus dem Schlüsselkanal 3 bzw. 5 herausgeschoben, als es der Schlüssel 7 vermag.If the key 7 is in one of the two key channels 3 or 5 introduced, the key 7 first hits against the one acting as a ramp End 21 'of the locking member 21 and thereby pushes it Locking member 21 back against the spring force, that is from the Key channel 3 or 5 out. At the same time, the ratchet tooth 25 is released the first recess 17. When the key 7 is inserted further take its crossbars 7 ', which engages in a groove 13, respectively Control disc 9 with. At the same time, the material section 15 runs with her Circumference past the ratchet tooth 25. Because of the eccentricity of the Lot of material 15, the locking member 21 is further from the Key channel 3 or 5 pushed out as the key 7 can.

Wenn der Schlüssel 7 vollständig eingeführt ist, also kurz bevor die Querstege 7' die Nuten 13 wieder verlassen würden, fällt der Sperrzahn 25 in eine der weiteren Ausnehmungen 19 ein. Dadurch ist die Steuerscheibe 9 in dieser Position fixiert. Die auf das Verriegelungsglied 21 wirkende Federkraft reicht dabei aus, um den Sperrzahn 25 auch bei Erschütterungen in der weiteren Ausnehmung 19 zu halten. Der erfindungsgemäße Sicherheitsschalter kann so ausgebildet sein, daß ausgehend von der fixierten Position des Steuerschiebers der Schlüssel 7 weiter in den Schlüsselkanal 3 oder 5 eingeführt werden kann in der Art eines Nachlaufes, die Querstege 7' also die Nuten 13 wieder verlassen.When the key 7 is fully inserted, just before the Crosspieces 7 'would leave the grooves 13 again, the ratchet tooth 25 falls in one of the further recesses 19. This is the control disc 9 fixed in this position. The one acting on the locking member 21 Spring force is sufficient to lock the ratchet tooth 25 even when shaken to hold in the further recess 19. The invention Safety switch can be designed so that starting from the fixed position of the spool key 7 further in the Key channel 3 or 5 can be introduced in the manner of a Trail, the crossbars 7 'so leave the grooves 13 again.

Beim Herausziehen des Schlüssels 7 wird die über die Steuerscheibe 9 von deren Materialpartie 15 auf den Sperrzahn 25 ausgeübte Kraft so groß, daß der Sperrzahn 25 aus der weiteren Ausnehmung 19 herausgedrückt wird und so die Steuerscheibe 9 für eine Drehung freigibt.When the key 7 is pulled out, the control disc 9 of whose material 15 exerted on the ratchet 25 force so large that the ratchet tooth 25 is pressed out of the further recess 19 and so releases the control disk 9 for rotation.

Beim zweiten Ausführungsbeispiel des erfindungsgemäßen Sicherheitsschalters ist ebenfalls ein Schaltergehäuse 101 mit einem Schlüsselkanal 105 vorgesehen. Ein längsgeschlitzter, gabelförmiger Schlüssel 107 ist in den Schlüsselkanal 105 einführbar. Eine Steuerscheibe 109, welche in den Schlüsselkanal 105 ragt, dreht sich beim Einführen des Schlüssels 107 dadurch, daß Querstege 107' des Schlüssels 107 in Nuten 113 eingreifen, welche auf beiden Seiten der Steuerscheibe 109 vorgesehen sind. Um die Drehachse 111 der Steuerscheibe 109 herum ist eine Materialpartie 115 an die Steuerscheibe 109 angeformt, die eine Flanke 117 aufweist.In the second embodiment of the invention Safety switch is also a switch housing 101 with a Key channel 105 provided. A slit, forked Key 107 can be inserted into key channel 105. A control disc 109, which protrudes into the key channel 105, rotates when the Key 107 in that transverse webs 107 'of the key 107 in grooves 113 engage, which is provided on both sides of the control disk 109 are. Around the axis of rotation 111 of the control disk 109 is one Material 115 formed on the control disc 109, the one flank 117.

Neben jeder Materialpartie 115 ist je ein Verriegelungsglied 121 vorgesehen, welches mit einem Langloch 123 die Drehachse 111 umschließt und nur in Fig. 2A dargestellt ist. Das Verriegelungsglied 121 ist senkrecht zum Schlüsselkanal 105 beweglich und mittels einer nicht dargestellten Feder abgestützt. Ein auf der Innenseite des Verriegelungsgliedes 121 vorgesehener Sperrzahn 125 liegt an der Flanke 117 der Materialpartie 115 an, solange der Schlüssel 107 sich außerhalb des Schlüsselkanals 105 befindet. A locking member 121 is located next to each material section 115 provided which encloses the axis of rotation 111 with an elongated hole 123 and is only shown in Fig. 2A. The locking member 121 is movable perpendicular to the key channel 105 and not by means of one illustrated spring supported. One on the inside of the Locking member 121 provided locking tooth 125 lies on the flank 117 of the material section 115 as long as the key 107 is outside of the key channel 105 is located.

In einem Randbereich der Steuerscheibe 109 sind auf beiden Seiten nutartige Ausnehmungen 119 vorgesehen, welche senkrecht zur radialen Richtung verlaufen und an einem Ende am Umfang der Steuerscheibe 109 münden. Dieser Randbereich kann bei einer Drehung der Steuerscheibe 109 in den Schlüsselkanal 105 gelangen.In an edge region of the control disk 109 are on both sides groove-like recesses 119 are provided, which are perpendicular to the radial Run direction and at one end on the circumference of the control disk 109 lead. This edge area can when the control disc rotates 109 get into the key channel 105.

Wenn der Schlüssel 107 in den Schlüsselkanal 105 eingeführt wird, drückt die Spitze des Schlüssels 107 das Verriegelungsglied 121 entgegen der Federkraft zurück, wobei der Sperrzahn 125 sich von der Flanke 117 löst. Die Querstege 107' des Schlüssels 107 nehmen die Steuerscheibe 109 so lange mit, bis die Querstege 107' sich in Einführrichtung betrachtet hinter der Steuerscheibe 109 befinden. Die Steuerscheibe 109 bewegt dabei einen in Fig. 2A angedeuteten Stößel, welcher wiederum den Schalter betätigt. In der Stellung, in der die Querstege 107' sich hinter der Steuerscheibe 109 befinden, sind die nutartigen Ausnehmungen 119 entlang des Schlüsselkanals 105 ausgerichtet, wie in Fig. 2C dargestellt. Der Schlüssel 107 kann nun weiter in den Schlüsselkanal 105 eingeführt werden in der Art eines Nachlaufs, wobei auf der Innenseite des Schlüssels 107 vorgesehene Absätze 127 in die nutartigen Ausnehmungen 119 eingreifen und damit die Steuerscheibe 109 fixieren.When the key 107 is inserted into the key channel 105, pushes the tip of the key 107 the locking member 121 against the Spring force back, the locking tooth 125 detaching from the flank 117. The crossbars 107 'of the key 107 take the control disk 109 so long with, until the crossbars 107 'are viewed behind in the direction of insertion the control disc 109 are. The control disk 109 moves one 2A indicated plunger, which in turn actuates the switch. In the position in which the crossbars 107 'are behind the control disk 109 are located, the groove-like recesses 119 along the key channel 105 aligned as shown in Fig. 2C. The key 107 can now be further introduced into the key channel 105 in the manner of a wake, provided on the inside of the key 107 Shoulders 127 engage in the groove-like recesses 119 and thus the Secure control disc 109.
