Description

Die Erfindung betrifft einen Befehlstaster in Scheibenelement-Bauweise mit einem Betätiger, der ein in eine Tragwand einbaubares Gehäuse und einen mittels Feder rückstellbaren hohlen Stößel aufweist, dessen äußeres Ende als von innen beleuchtbare Drucktaste ausgebildet ist, mit einem Kupplungsstück, das mehrere Steckplätze zur Aufnahme von parallel nebeneinander anzuordnenden scheibenförmigen Elementen aufweist, und mit Elementen, die u. a. als Schaltelemente mit einem in Stößelbewegungsrichtung verschiebbar gelagerten und vom Stößel betätigbaren beweglichen Organ und mit wenigstens einem Kontaktsatz oder als Leuchtelement mit einer Lampenfassung oder anderen Beleuchtungseinheit ausgebildet sind.The invention relates to a command button in the disc element design with an actuator which has a housing which can be built into a supporting wall and a hollow plunger which can be reset by means of a spring, the outer end of which is designed as a push button which can be illuminated from the inside, with a coupling piece which has a plurality of slots for receiving has parallel to be arranged disc-shaped elements, and with elements that u. a. are designed as switching elements with a movable member which is displaceable in the tappet movement direction and can be actuated by the tappet and with at least one contact set or as a lighting element with a lamp holder or other lighting unit.

Diese Art Befehltaster ist bekannt aus DE-A- 3 014 639This type of command button is known from DE-A-3 014 639

Ein bekannter Befehlstaster dieser Gattung wird unter dem Warenzeichen RAFIX S 22 von der Firma Rafi GmbH & Co. vertrieben und ist in dem als Anlage beigefügten Prospektblatt dargestellt. Der als Betätigungselement bezeichnete Betätiger hat eine runde Drucktaste, das als Kupplung bezeichnete Kupplungsstück hat drei Steckplätze. Die Schaltelemente sind als Kontaktelemente bezeichnet. Ihre beweglichen Organe haben ein flaches, oben überstehendes Ende und tragen je eine Kontaktbrücke, die je nach dem Typ des betreffenden Schaltelements als Öffner oder Schließer wirkt. Die Anschlußklemmen befinden sich an der vom Betrachter abgewandten Unterseite. Das Leuchtelement, welches nur am mittleren Steckplatz des Kupplungsstücks angebracht werden kann, enthält lediglich die Anschlußklemmen für die oben aufgesetzte Lampenfassung.A well-known control buttons of this type is sold under the trademark RAFIX S 22 by the company Rafi GmbH & Co. and is shown in the annexed leaflet. The actuator designated as the actuator has a round push button, the coupling piece referred to as the clutch has three slots. The switching elements are referred to as contact elements. Your mobile organs have a flat, top protruding end and each carry a contact bridge, which acts as a break or make contact depending on the type of switching element concerned. The connection terminals are located on the underside facing away from the viewer. The light element, which can only be attached to the middle slot of the coupling piece, only contains the connection terminals for the lamp holder attached above.

Infolge der hohlrunden Form des Stößels, die zur Aufnahme der Lampe und Lampenfassung zur Beleuchtung der Drucktaste erforderlich ist, erreicht der Stößel die beweglichen Organe der Schaltelemente nur dann, wenn diese in den äußeren Steckplätzen eingefügt sind. Wenn auf das Leuchtelement verzichtet werden kann und ein drittes Schaltelement erwünscht ist, kann dieses zwar anstelle des Leuchtelements am mittleren Steckplatz eingefügt werden, jedoch ist dann nachteiligerweise ein besonderes Druckstück in den Stößel einzufügen, um dessen Stirnfläche im Zentrum auszufüllen, so daß auch das bewegliche Organ des mittleren Schaltelements erreicht und vom Stößel mitbewegt wird.As a result of the hollow, round shape of the plunger, which is required for accommodating the lamp and lamp holder for illuminating the pushbutton, the plunger only reaches the movable elements of the switching elements when they are inserted in the outer slots. If the lighting element can be dispensed with and a third switching element is desired, this can be inserted instead of the lighting element in the middle slot, but then disadvantageously a special pressure piece has to be inserted into the plunger in order to fill its end face in the center, so that the movable one Organ of the middle switching element is reached and moved by the plunger.

Wenn derartige Befehlstaster zur Handsteuerung von Motorantrieben mit gegenläufigen Drehrichtungen verwendet werden, ergibt sich das folgende Problem, beispielsweise wenn der Motor ein Tor öffnet und schließt und wie üblich für jede Drehrichtung ein Befehlstaster vorgesehen ist, der mit einem "Öffner"-Schaltelement und mit einem "Schließer"-Schaltelement bestückt ist. Dabei unterbricht der Öffner im Befehlstaster "Rechtslauf" den Schaltkreis für den Linkslauf und umgekehrt (elektrische Verriegelung). Es kann geschehen, daß die Arbeitskontaktbrücke mit ihren Gegenkontaktstücken verschweißt und beim Loslassen der Drucktaste hängenbleibt. Der im anderen Schaltelement enthaltene Öffner geht jedoch in seine Ruhestellung zurück und erfüllt somit seine Verriegelungsfunktion nicht mehr. Der bekannte Befehlstaster ist somit für Schaltanordnungen, bei denen bestimmte Abhängigkeiten zwischen den einzelnen Schaltelementen zu beachten sind, nicht geeignet.If such command buttons are used for manual control of motor drives with opposite directions of rotation, the following problem arises, for example when the motor opens and closes a gate and, as usual, a command button is provided for each direction of rotation, which has an "opener" switching element and one "Normally open" switching element is equipped. The NC contact in the "clockwise" command button interrupts the circuit for counterclockwise rotation and vice versa (electrical locking). It can happen that the working contact bridge is welded to its counter contact pieces and gets stuck when the push button is released. The one contained in the other switching element However, the opener returns to its rest position and thus no longer fulfills its locking function. The known command button is therefore not suitable for switching arrangements in which certain dependencies between the individual switching elements have to be observed.

Häufig besteht das Bedürfnis, bei den beschriebenen und ähnlichen Befehlstastern die Schaltelemente nicht tastend, sondern rastend zu betätigen, so daß durch einen Druck auf die Drucktaste die Kontaktsätze in die eine Stellung und nach Loslassen der Drucktaste durch erneutes Tasten in die andere Stellung gebracht werden. Es ist aus der DE-C 11 69 549 und (ohne Nachweis) auch bei Befehlstastern in Scheibenelement-Bauweise bekannt, den Mechanismus zur sogenannten Hoch- und Tiefverrastung im Betätiger unterzubringen. Das hat zur Folge, daß im Sortiment ein Betätiger ohne und ein Betätiger mit diesem Mechanismus auf Vorrat gehalten werden muß. Ein weiterer Nachteil dieser bekannten Bauform besteht darin, daß bei einer später notwendigen Änderung der Schaltfunktion von rastend auf tastend oder umgekehrt der in die Tragplatte eingebaute Betätiger ausgewechselt werden muß, was sehr hinderlich ist. Und stets können sämtliche Kontaktsätze entweder nur fastend oder nur rastend betätigt werden (keine Mischung).Frequently, there is a need to actuate the switching elements in the described and similar command pushbuttons rather than by pushing, so that by pressing the pushbutton the contact sets are brought into one position and after releasing the pushbutton by pressing again in the other position. It is known from DE-C 11 69 549 and (without proof) also in the case of command buttons in disk element design to accommodate the mechanism for so-called high and low locking in the actuator. As a result, an actuator without and an actuator with this mechanism must be kept in stock in the range. Another disadvantage of this known design is that when the switching function is later changed from latching to momentary or vice versa, the actuator built into the support plate has to be replaced, which is very cumbersome. And all contact sets can always be actuated either only fasting or only latching (no mixture).

Der Erfindung liegt die Aufgabe zugrunde, einen Befehlstaster der einleitend bezeichneten Art vorzuschlagen, dessen Betätiger kein besonderes Druckstück oder sonstiges Zusatzteil erfordert, wenn anstelle des Leuchtelements am mittleren Steckplatz ein Schaltelement eingefügt wird. Außerdem soll der Befehlstaster auch bei Schaltungen mit elektrischer Verriegelung verwendbar sein.The invention has for its object to propose a command button of the type described in the introduction, the actuator does not require a special pressure piece or other additional part if a switching element is inserted in the middle slot instead of the lighting element. In addition, the command button should also be usable for circuits with electrical locking.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die beweglichen Organe der scheibenförmigen Elemente miteinander formschlüssig kuppelbar sind. Dies kann durch eine einfügbare Querverbindung erreicht werden oder insbesondere dadurch, daß an den zur Scheibenebene parallelen Seitenflächen der beweglichen Organe Aussparungen und/oder senkrecht zur Scheibenebene abstehende Vorsprünge vorgesehen sind, die in die Aussparungen eingreifen.This object is achieved in that the movable members of the disc-shaped elements are positively coupled to each other. This can be achieved by an insertable cross-connection or, in particular, in that recesses and / or projections protruding perpendicular to the plane of the disc are provided on the side surfaces of the movable members parallel to the plane of the disc and engage in the recesses.

Infolge einer derartigen seitlichen Kupplung kann das bewegliche Organ desjenigen Schaltelements, welches am mittleren Steckplatz in der Stößelachse sitzt, vom beweglichen Organ wenigstens eines daneben angebrachten Schaltelements mitbewegt werden. Das Leuchtelement kann aber auch ein lose bewegliches Organ aufweisen, das nur dazu dient, die beiderseits anschließenden Schaltelemente miteinander zu kuppeln, beispielsweise, wenn diese als Öffner und Schließer innerhalb einer elektrischen Verriegelungsschaltung funktionieren. Es ist auch möglich, mehr als drei Steckplätze am Kupplungsstück vorzusehen, wobei die weiter außen eingefügten Schaltelemente ebenfalls über entsprechende Kupplungen angetrieben werden. Die Zahl nebeneinander anzuordnender Elemente ist somit nicht mehr begrenzt und ein Zusatzteil zur Veränderung der Stirnfläche des Betätigerstößels ist nicht mehr erforderlich.As a result of such a lateral coupling, the movable member of the switching element which is seated at the central slot in the tappet axis can be moved by the movable member of at least one switching element attached next to it. However, the light-emitting element can also have a loosely movable element which only serves to couple the switching elements which connect on both sides to one another, for example if they function as openers and closers within an electrical locking circuit. It is also possible to provide more than three slots on the coupling piece, the switching elements inserted further out also being driven via corresponding couplings. The number of elements to be arranged next to one another is thus no longer limited and an additional part for changing the end face of the actuator plunger is no longer required.

Eine besonders zweckmäßige Ausführungsform der Kupplungsanordnung besteht darin, daß an den beweglichen Organen an einer Seitenfläche ein Vorsprung und eine den Vorsprung oben und unten abstützende Aussparung in gleicher Höhe und in gleichem Abstand von der Quermittelebene sowie an der anderen Seitenfläche fluchtend mit dem Vorsprung eine weitere Aussparung vorgesehen sind. Man erreicht dadurch, daß zwei Elemente sowohl mit einander zugekehrten Vorsprüngen als auch in der Weise miteinander gekuppelt werden können, daß der Vorsprung des einen Elements in die weitere Aussparung des anderen Elements eingreift. Man kann also beim Zusammenfügen eines Pakets von mehreren Elementen erreichen, daß an den Enden kein Vorsprung übersteht.A particularly expedient embodiment of the coupling arrangement consists in that a projection on the movable members on one side surface and a recess supporting the projection above and below at the same height and at the same distance from the transverse median plane and on the other side surface in alignment with the projection another recess are provided. It is achieved in that two elements can be coupled with each other facing projections as well as in such a way that the projection of one element in the further recess of the other element. When assembling a package of several elements, one can ensure that there is no protrusion at the ends.

Die Erfindung ermöglicht eine wesentliche Weiterbildung eines gattungsgemäßen Befehlstasters, welche darin besteht, daß ein besonderes scheibenförmiges Element vorgesehen ist, das ein bewegliches Organ und einen Mechanismus zur Hoch- und Tiefverrastung desselben aufweist. Dieses Element kann an irgendeinem Steckplatz des Kupplungstücks angefügt werden, wodurch erreicht wird, daß alle mit ihm gekuppelten Schaltelemente die rastende Funktion übernehmen. Es ist also vorteilhafterweise nicht mehr erforderlich, den Betätiger gegen einen Betätiger mit Hoch- und Tiefverrastung auszuwechseln, sondern es genügt, das rastende Element an einem leeren Steckplatz anzufügen oder eines der bisherigen Elemente durch das rastende Element zu ersetzen.The invention enables an essential further development of a generic push button, which consists in the fact that a special disk-shaped element is provided, which has a movable element and a mechanism for locking it up and down. This element can be added to any slot of the coupling piece, which ensures that all switching elements coupled to it take over the locking function. It is therefore advantageously no longer necessary to replace the actuator with an actuator with high and low latching, but it suffices to add the latching element to an empty slot or to replace one of the previous elements with the latching element.

Da die bekannten Leuchtelemente raummäßig schlecht ausgenutzt sind, kann das Element mit Hoch- und Tiefverrastung seines beweglichen Organs vorteilhafterweise auch als Leuchtelement ausgebildet sein, derart, daß eine Lampenfassung über dem beweglichen Organ angeordnet ist. Der Rastmechanismus wird somit vom Betätiger in das Leuchtelement verlegt. Dadurch wird die Raumausnutzung wesentlich verbessert.Since the known lighting elements are poorly used in terms of space, the element with the up and down latching of its movable member can advantageously also be designed as a lighting element in such a way that a lamp holder is arranged above the movable member. The locking mechanism is thus moved by the actuator into the lighting element. This significantly improves the use of space.

Insgesamt wird mit der Erfindung ein außerordentlich variables und vielseitiges Befehlstaster-System geschaffen, das die Montage erleichtert und durch wenig Einzelteile die Vorratshaltung entlastet.Overall, the invention creates an extraordinarily variable and versatile command button system, which simplifies assembly and relieves the need to hold stocks with fewer individual parts.

The actuator housing is divided into a widened head (3) and a cylindrical socket (4), the latter of which is inserted through the supporting wall (2) and fastened by means of a screw ring (5). A hollow, cylindrical plunger (6) is slidably guided in the socket (4). The plunger face (see also Fig. 3) is widened like a flange. At the outer end, the plunger (6) is designed as a push button (7). It is kept in the position shown by means of a spring (8).

Ein weiterer Bestandteil des Befehlstasters ist ein ebenfalls nur schematisch dargestelltes Kupplungsstück (9), das auf geeignete Weise am Stutzen (4) befestigt und derart ausgebildet ist, daß wahlweise ein bis drei scheibenförmige Elemente (10, 11, 12) in paralleler Anordnung daran festgemacht werden können, vorzugsweise durch lösbare Steckverbindungen. Die Anordnung ist so getroffen, daß das mittlere Element, im Beispiel ein Leucht- und Rastelement (11), den mittleren Steckplatz in Verlängerung der Betätigerachse besetzt.Another component of the command button is a coupling piece (9), also shown only schematically, which is fastened in a suitable manner to the connecting piece (4) and is designed in such a way that one to three disk-shaped elements (10, 11, 12) are attached to it in a parallel arrangement can be, preferably by detachable connectors. The arrangement is such that the middle element, in the example a lighting and locking element (11), occupies the middle slot in the extension of the actuator axis.

Die wesentlichen Einzelteile des Leucht- und Rastelements (11), die im einzelnen noch anhand von Fig. 7 erläutert werden, sind: Eine oben aufsitzende Lampenfassung (13) für eine Glühlampe (14) (Fig. 1), die in den hohlen Stößel (6) hinein vorsteht und das Tastfeld der Drucktaste (7) beleuchtet, ein in Stößelbewegungsrichtung verschiebbar gelagertes bewegliches Organ (15) und ein mit diesem zusammenwirkender Rastmechanismus (16). Das bewegliche Organ (15) hat eine quer durchgehende rechteckige Aufnahmeöffnung (17), welche durch rechteckige Fenster (18) an beiden Breitseiten des Elementengehäuses in jeder Stellung des beweglichen Organs (15) zugänglich ist.The essential individual parts of the lighting and latching element (11), which will be explained in more detail with reference to FIG. 7, are: A lamp holder (13) for an incandescent lamp (14) (FIG. 1) seated at the top, which is in the hollow plunger (6) protrudes and illuminates the touch field of the pushbutton (7), a movable member (15) mounted displaceably in the tappet movement direction and a latching mechanism (16) which interacts with it. The movable member (15) has a transverse rectangular receiving opening (17) which is accessible through rectangular windows (18) on both broad sides of the element housing in any position of the movable member (15).

Als Einzelteile der Schaltelemente (10, 12) sind auch in den Figuren 8 und 9 nur das jeweilige bewegliche Organ (19) gezeigt. Es ragt mit seinem quadrischen oberen Ende über das Elementengehäuse hinaus und wird bei Betätigung der Drucktaste (7) von der Stirnfläche des Stößels (6) nach unten gedrückt. Die Rückstellfeder sowie die Kontaktsätze, d. h. je nach Ausführungsform ein oder mehrere Öffner oder Schließer, sind in der schematischen Darstellung nicht wiedergegeben. Zur gegenseitigen Kupplung haben die beweglichen Organe (19) an einer Seite einen senkrecht zur Scheibenfläche abstehenden Vorsprung (20) von rechteckigem Querschnitt. Unmittelbar neben diesem Vorsprung befindet sich eine gleichgroße Aufnahmeöffnung (21), die durchgehen kann oder, im Beispiel bis zu der zur Scheibenfläche parallelen Mittelebene des Schaltelements reicht. Auf der gegenüberliegenden Seite hat jedes der beweglichen Organe (19) ebenfalls eine Aufnahmeöffnung (22), die mit dem Vorsprung (20) fluchtet und den gleichen Querschnitt wie dieser hat. Fenster (18) zu beiden Seiten des Elementengehäuses gestatten - wie bei dem Leuchtelement - den Zugang zu den Aufnahmeöffnungen (21 und 22) sowie den Durchtritt des Vorsprungs (20). Die Fenster (18) sind um die Hublänge nach unten verlängert, so daß die Hubbewegung des beweglichen Organs (19) nicht behindert wird.As individual parts of the switching elements (10, 12), only the respective movable member (19) is also shown in FIGS. 8 and 9. It protrudes with its square upper end beyond the element housing and is pressed down by pressing the push button (7) from the end face of the plunger (6). The return spring as well as the contact sets, d. H. depending on the embodiment, one or more break contacts or make contacts are not shown in the schematic illustration. For mutual coupling, the movable members (19) have on one side a projection (20) of rectangular cross section projecting perpendicularly to the disk surface. Immediately next to this projection there is a receiving opening (21) of the same size, which can pass through or, in the example, extends to the central plane of the switching element parallel to the disk surface. On the opposite side, each of the movable members (19) also has a receiving opening (22) which is aligned with the projection (20) and has the same cross section as this. Windows (18) on both sides of the element housing allow - as with the lighting element - access to the receiving openings (21 and 22) and the passage of the projection (20). The windows (18) are extended downwards by the stroke length, so that the lifting movement of the movable member (19) is not hindered.

Die Elemente (10 bis 12) nach den Figuren 1 bis 3 sind so angeordnet, daß die Vorsprünge (20) der beiden Schaltelemente (10 und 12) von beiden Seiten in die Aufnahmeöffnung (17) des beweglichen Organs (15) des Leucht- und Rastelements (11) eingreifen. Dadurch sind diese drei beweglichen Organe miteinander gekuppelt. Das bewegliche Organ (15) macht sämtliche Bewegungen der beiden anderen beweglichen Organe (19) mit. Umgekehrt werden aber auch die beweglichen Organe (19) bei der Verrastung des beweglichen Organs (15) mit Hilfe des Rastmechanismus (16) in der unteren oder oberen Stellung festgehalten. Beide Schaltelemente (10 und 12) wirken somit rastend, d. h. als Schalter. Drückt man auf die Drucktaste (7), so bewegen sie sich nach unten und werden dort durch den Rastmechanismus (16) festgehalten. Nach dem Loslassen bewegt sich die Drucktaste (7) und der Stößel allein zurück. Bei erneutem Drücken der Drucktaste (7) wird die Verrastung gelöst und die drei beweglichen Organe gehen gemeinsam in die obere Ausgangsstellung zurück. Die Montage der drei Elemente (10 bis 12) erfolgt in der Weise, daß diese zunächst senkrecht zur Scheibenebene ineinander gefügt werden und dann der ganze Block in Stößelbewegungsrichtung in das Kupplungsstück (9) eingefügt und beispielsweise verklinkt wird.The elements (10 to 12) according to Figures 1 to 3 are arranged so that the projections (20) of the two switching elements (10 and 12) from both sides in the receiving opening (17) of the movable member (15) of the light and Engage the locking element (11). As a result, these three movable organs are coupled together. The movable member (15) follows all the movements of the other two movable members (19). Conversely, the movable organs (19) are locked when the movable organ (15) is locked with the aid of the Locking mechanism (16) held in the lower or upper position. Both switching elements (10 and 12) thus act latching, ie as a switch. If you press the push button (7), they move downwards and are held there by the locking mechanism (16). After releasing, the push button (7) and the plunger alone move back. When the push button (7) is pressed again, the catch is released and the three movable elements return together to the upper starting position. The three elements (10 to 12) are assembled in such a way that they are first inserted into one another perpendicular to the plane of the disc and then the entire block is inserted into the coupling piece (9) in the direction of the tappet movement and, for example, is latched.

Die beschriebene Funktion ändert sich nicht, wenn ein Schaltelement, beispielsweise (12), weggelassen wird oder weitere Schaltelemente (23) angefügt werden, wie dies strichpunktiert dargestellt ist. Dazu ist allerdings ein entsprechend verbreitertes Kupplungsstück (24) erforderlich.The function described does not change if a switching element, for example (12), is omitted or additional switching elements (23) are added, as is shown in broken lines. However, a correspondingly widened coupling piece (24) is required for this.

Läßt man bei dem Leucht- und Rastelement (11) den Rastmechanismus (16) und das bewegliche Organ (15) weg, so hat man ein reines Leuchtelement, wie an sich bekannt. Die beiden Schaltelemente arbeiten dann tastend, d. h. sie gehen nach dem Loslassen der Drucktaste (7) jedes Mal wieder in die Ausgangsstellung zurück.If the locking mechanism (16) and the movable member (15) are omitted from the lighting and locking element (11), one has a pure lighting element, as is known per se. The two switching elements then work groping, i. H. after releasing the push button (7) they go back to the starting position each time.

Ist die Beleuchtung der Drucktaste (7) nicht erforderlich, so kann anstelle des Leuchtelements (11) in die Mitte eine weiteres Schaltelement (25) eingefügt werden, was Fig. 11 zeigt. Es ist auf beiden Seiten mit seinen Nachbarelementen verkuppelt und alle drei beweglichen Organe arbeiten gemeinsam in tastender Funktion.If it is not necessary to illuminate the pushbutton (7), a further switching element (25) can be inserted in the center instead of the lighting element (11), as shown in FIG. 11. It is coupled with its neighboring elements on both sides and all three movable organs work together in a groping function.

Schließlich kann die Bestückung gemäß Fig. 4 auch in der Weise vorgenommen werden, daß zwar in der Mitte das Leucht- und Rastelement (11) angebracht und das eine Schaltelement (10) mit diesem gekuppelt ist, das andere Schaltelement (12) jedoch seitenverkehr eingefügt ist, so daß der Vorsprung vom Leucht- und Rastelement abgewandt ist und nach außen steht. In dieser Konfiguration arbeitet das Schaltelement (10) rastend und das Schaltelement (12) tastend.Finally, the equipping according to FIG. 4 can also be carried out in such a way that, although the lighting and latching element (11) is attached in the middle and one switching element (10) is coupled to it, the other switching element (12) is inserted on the side is, so that the projection faces away from the lighting and locking element and stands outwards. In this configuration, the switching element (10) operates in a latching manner and the switching element (12) in a tactile manner.

Zur Vervollständigung wird im folgenden ein konstruktiv detailliert ausgebildetes Leucht- und Rastelement anhand von Fig. 7 beschrieben. Das Elementengehäuse (30) aus Isolierstoff besteht aus zwei zusammenpassenden Halbschalen, von denen nur die hintere dargestellt ist. Man erkennt das schon erwähnte Fenster (18) sowie Öffnungen zum Einführung der Anschlußdrähte für die Lampe und zum Einstecken des Schraubenziehers für die Klemmschrauben. In das Gehäuse sind zwei Metallbügel (31) und (32) eingesetzt. Sie weisen an ihrem oberen abgewinkelten Ende Klemmfinger (33) auf. Die Klemmfinger des einen Bügels verbinden diesen mit der Bajonettverschluß-Fassung (13) und der andere Bügel (32) ist auf gleiche Weise mit einer Blattfeder (34) verbunden, welche den anderen Anschluß für die Glühlampe bildet. Die unteren Enden der Metallbügel sind mit Schraubgewinde und Deckplatte (35) zum Anschluß von Leitungsdrähten versehen.To complete this, a structurally detailed lighting and locking element is described below with reference to FIG. 7. The element housing (30) made of insulating material consists of two matching half shells, of which only the rear one is shown. One recognizes the already mentioned window (18) as well as openings for the introduction of the connecting wires for the lamp and for inserting the screwdriver for the clamping screws. Two metal brackets (31) and (32) are inserted into the housing. They have clamping fingers (33) at their upper angled end. The clamping fingers of one bracket connect it to the bayonet fitting socket (13) and the other bracket (32) is connected in the same way to a leaf spring (34) which forms the other connection for the incandescent lamp. The lower ends of the metal brackets are provided with a screw thread and cover plate (35) for connecting lead wires.

In dem Elementegehäuse (30) ist ein Rastschieber (36) hin und her bewegbar gelagert. Er steht unter dem Einfluß zweier gegeneinander wirkender Druckfedern (37). Ferner ist in dem Elementegehäuse das bewegliche Organ (15) in Bewegungsrichtung des Stößels des Befehlstasters beweglich gelagert. Das bewegliche Organ (15) umfaßt den Rastschieber (36) gabelförmig. Am Ende wenigstens einer Gabelzinke ist ein Stift (38) quer eingesetzt, der mit einer Nut in Form einer Herzkurve am Rastschieber (36) zusammenwirkt. Die Form dieser Herzkurve ist im Prinzip in DE-PS 11 69 549 beschrieben. Diese Anordnung bewirkt, wie in der genannten Patentschrift erläutert, eine Hoch- und Tiefverrastung des beweglichen Organs (15), wobei zu berücksichtigen ist, daß dieses infolge der Kupplung an ein Schaltelement unter der Wirkung der Rückstellfeder des beweglichen Organs (19) dieses Schaltelements steht.A locking slide (36) is mounted so that it can move back and forth in the element housing (30). It is under the influence of two pressure springs acting against each other (37). Furthermore, the movable member (15) is movably mounted in the element housing in the direction of movement of the plunger of the command button. The movable member (15) comprises the locking slide (36) in a fork shape. At the end of at least one fork tine, a pin (38) is inserted transversely a groove in the form of a heart curve on the locking slide (36) interacts. The shape of this heart curve is described in principle in DE-PS 11 69 549. This arrangement, as explained in the cited patent, causes the movable member (15) to be locked up and down, taking into account that this is due to the coupling to a switching element under the action of the return spring of the movable member (19) of this switching element .

Anhand von Fig. 10 werden die Einzelheiten eines Schaltelements mit Ruhekontakt (Öffner) erläutert. Wie bei dem Leucht- und Rastelement nach Fig. 7 ist ein Isolierstoffgehäuse vorgesehen, in welches zwei Metallbügel (39) spiegelbildlich eingefügt sind. Diese haben unten einen Leitungsanschluß wie beschrieben und die oberen Enden sind ebenfalls abgewinkelt. In die untere Fläche der oberen Abwinkelungen ist je eine Edelmetallwarze eingesetzt. Diese arbeiten mit einer beweglichen Kontaktbrücke (40) zusammen, die von dem beweglichen Organ (19) gehalten ist. Sie durchsetzt dieses in Querrichtung. Das bewegliche Organ (19) ist im Gehäuse in Stößelbewegungsrichtung verschiebbar geführt und steht unter dem Einfluß einer Druckfeder (41), die es nach oben drückt. An dem beweglichen Organ (19) sind der Vorsprung (20) und die Aufnahmeöffnung (21) erkennbar.
