- the accessory is housed in pockets in the housing of the electrical switch.
- the accessory is typically covered with an accessory cover to protect the accessory from unauthorized access.
- the accessory lid itself is often designed so that when switched on this can not be removed from the housing of the electrical switch. For safety reasons, it should be prevented that the electrical switch is switched on when the accessory cover is open.
- an electrical switch comprising a blocking means which, in a blocking position, prevents the triggering of the switch and the opening of the contacts.
- the blocking element for blocking the movement of a handle or a shift lever of an electrical switch is switchable between at least two positions and in the first position, the blocking element can block the movement of the handle or the shift lever and in the second position the blocking element can not block the movement of the handle or the lever.
- the advantage here is that the electrical switch can not be switched on manually with removed accessory cover. This is important to protect a surgeon and prevent misuse of the electrical switch.
- the blocking element is a blocking rocker, which is mounted pivotably about a rotation axis D.
- the blocking rocker may comprise a bearing, and this may be formed as a rotation axis D.
- the blocking rocker may include a first contour configured to block the handle or the shift lever of an electrical switch.
- the blocking rocker may comprise a second contour, which is designed to cooperate with a component of the electrical switch for pivoting the blocking rocker.

- FIG. 1 an electrical switch 100 is shown in a side sectional view.
- the electrical switch 100 comprises a handle 180, which is in the illustration of Figure 1 in the off position.
- the handle 180 is actuated along a circular path from an off position, which in the FIG. 1 corresponds to the right position, in an on position, which in the FIG. 1 would correspond to a left position.
- the handle 180 comprises an extension 181 which can interact with a blocking element 200.
- the blocking element 200 is designed as a blocking rocker.
- the blocking rocker 200 is configured to block the movement of the handle 180 by being pivoted into the movement of the handle 180.
- the blocking rocker 200 is pivotally mounted with its bearing 210 about a rotation axis D.
- the blocking rocker 200 is pivotable between at least two positions. In its first position it blocks the movement of the handle 180 and in its second position it can not block the movement of the handle 180.
- an accessory cover 150 is placed on the housing of the electrical switch 100. This closes the so-called accessory pockets, in which accessories can be installed in the electrical switch 100.
- the accessory cover 150 ensures that the blocking rocker 200 is moved to the second position, in which it can not block the movement of the handle 180. This happens because, for example, a second contour 230 of the blocking rocker 200 cooperates with the accessory cover 150 of the electrical switch 100.
- the electrical switch 100 can thus be reciprocated between its different positions without restriction.
- the blocking rocker 200 may be formed substantially triangular with the first corner as a bearing 210, the second corner as a first contour 220 and the third corner as a second contour 230th
- the blocking rocker 200 blocks in its first position the movement of the handle 180. This may be direct or also indirect. Furthermore, the blocking rocker 200 may block the shift lever of an electrical switch 100.
- the electrical switch 100 may include a mechanism that prevents the accessory cover 150 from being removed in the on position of the electrical switch 100. This mechanism can thus ensure that the accessory cover can be removed only in the case of a handle 180 in the off position of the electric switch 100. Because, according to the representation of the FIG. 2 the accessory cover 150 no longer cooperates with the blocking rocker 200, the blocking rocker 200 is pivoted to the first position in which it can block the movement of the handle 180. The second contour 230 of the blocking rocker 200 does not interact with the accessory cover 150. This tilts according to the representation of FIG. 2 the blocking rocker 200 to the right about its axis of rotation D.
- the angle of rotation of the blocking rocker 200 is denoted by ⁇ , for example. Characterized in that the blocking rocker has rotated 200 by the angle ⁇ in a clockwise direction, there is now a first contour 220 of the locking rocker 200 in the path of movement of the handle 180. This is in more detail in FIG. 3 explained.
- FIG. 3 For example, the electrical switch 100 is shown and the handle 180 has been moved leftward toward the on position by an angle ⁇ .
- the first contour 220 of the blocking rocker 200 now blocks the handle 180 so that it comes into mechanical contact with the extension 181.
- This blocking position is preferably provided before the tilting point in the direction of the on position of the handle 180.
- FIG. 4 the blocking rocker 200 is shown enlarged according to the position of the electrical switch in the FIG. 3 ,
- the blocking rocker 200 is pivoted to the first position.
- the first contour 220 of the blocking rocker 200 blocks the path of movement of the handle 180.
- the extension 181 of the handle 180 abuts the first contour 220 of the blocking rocker, which prevents the handle can be moved further in the direction of the on position of the electrical switch.
- this additionally comprises an elastic element 300, which may be formed for example as a spring or correspondingly shaped plastic.
- the spring 300 causes the blocking rocker 200, if it does not cooperate with the accessory cover 150, is transferred to the first position. According to the representations in the FIGS. 1 to 4 This means that the spring 300 rotates the blocking rocker 200 in a clockwise direction. It can be provided that the blocking rocker 200 abuts against a stop, for example against an edge 190 in the housing cover of the electrical switch 100, and thus the movement of the blocking rocker 200 in the clockwise direction is limited.
- FIG. 5 the electrical switch 100 is shown in a plan view of the electrical switch 100.
- the handle 180 extends through the accessory cover 150.
- the blocking rocker 200 is located within the housing of the electrical switch 100 and is in the illustration of FIG. 5 not visible.
- FIG. 6 the electrical switch 100 is again shown in a plan view, with the accessory cover 150 removed.
- the electrical switch 100 comprises a handle 180, which is in a blocking position by the interaction with the blocking rocker 200.
- the blocking rocker 200 protrudes with its second contour 230 from the housing of the electrical Switch 100 out, so that this second contour 230 can cooperate with the accessory cover 150.
- the blocking rocker 200 is located according to the FIG. 6 in its first position and thus the second contour 230 in its stop position.
- the blocking rocker 200 is pivoted about the axis of rotation D by the angle ⁇ .
- the second contour 230 may also cooperate with another component (150) of the electrical switch (100) as the accessory cover, for example with a cover, an adapter plate or a drive, in particular a motor drive, a rotary drive or a door coupling drive.
- the kinematic and kinetic regulation of the blocking mechanism with the blocking element 200 is determined by the elastic element 300.
- the sensitivity with respect to the dynamics is controllable.
- the end of the rotational movement and thus the achievement of the blocking position of the blocking rocker 200 can be determined by a geometric design of the guide pocket. Due to the supporting force of the elastic element, the blocking element 200 is pressed against the edge 190 in the housing cover and held in position. The limitation of the movement can be solved analogously thereto via another boom or by another design feature.
- the blocking element 200 Due to the lack of contact between the blocking element 200 and accessory cover 150, the blocking element 200 is rotated by the force of the elastic element 300 and transferred to the blocking position, its first position, and held there. If the operator moves the handle 180 in the direction of the on position, it is blocked in front of the latching point of the lock. In this case, the handle 180 meets the first contour 220 of the blocking rocker 200.
- the lock of the electrical switch 100 is prevented from snapping around and thus prevents a contact contact of the electrical contacts of the electrical switch 100.
- a conceivable embodiment is to place the blocking element 200 in the housing of a switch. Due to the gear ratio only a relatively small angle of rotation ⁇ for blocking the handle 180 and thus the switching mechanism is required. Due to the favorable positioning of the axis of rotation D of the blocking rocker 200, a closing moment is introduced to the blocking rocker 200 upon contact introduction of the handle 180 onto the first contour 220 of the blocking rocker 200 as a result of the contact force. Consequently, the mechanism is brought into self-locking and avoided a solution of the blockage.
- the contact surface of the housing of the electrical switch 100 at the upper end of the blocking element 200 and the early stop position, for example in the upper housing part allow for easy Reseten the mechanics. This is made possible by the large lever arms of the contact force to the pivot point of the blocking element 200.

Im Ausführungsbeispiel ist das Blockierelement 200 als Blockierwippe ausgeführt. Die Blockierwippe 200 ist so ausgestaltet, dass sie die Bewegung der Handhabe 180 blockieren kann, indem sie in die Bewegung der Handhabe 180 eingeschwenkt werden kann. Dazu ist die Blockierwippe 200 mit ihrer Lagerstelle 210 um eine Drehachse D schwenkbar gelagert. Die Blockierwippe 200 ist zwischen mindestens zwei Positionen schwenkbar. In ihrer ersten Position blockiert sie die Bewegung der Handhabe 180 und in ihrer zweiten Position kann sie nicht die Bewegung der Handhabe 180 blockieren.In the exemplary embodiment, the
Auf das Gehäuse des elektrischen Schalters 100 ist ein Zubehördeckel 150 aufgesetzt. Dieser verschließt die sogenannten Zubehörtaschen, in denen Zubehöre im elektrischen Schalter 100 eingebaut sein können. Der Zubehördeckel 150 sorgt dafür, dass die Blockierwippe 200 in die zweite Position bewegt wird, in der sie nicht der Bewegung der Handhabe 180 blockieren kann. Dies geschieht dadurch, dass beispielsweise eine zweite Kontur 230 der Blockierwippe 200 mit dem Zubehördeckel 150 des elektrischen Schalters 100 zusammenwirkt. Dadurch, dass durch den Zubehördeckel 150 die Blockierwippe 200 in der zweiten Position gehalten wird, kann nun der Fortsatz 181 der Handhabe 180 nicht von der Blockierwippe 200 blockiert werden. Der elektrische Schalter 100 kann somit zwischen seinen unterschiedlichen Stellungen ohne Einschränkung hin- und herbewegt werden.On the housing of the

Die zweite Kontur 230 kann auch mit einem anderen Bauteil (150) des elektrischen Schalters (100) als dem Zubehördeckel zusammenwirken, beispielsweise mit einem Deckel, einer Adapterplatte oder einem Antrieb, insbesondere einem Motorantrieb, einem Drehantrieb oder einem Türkopplungsantrieb.The
Die kinematische und kinetische Regulation des Blockiermechanismus mit dem Blockierelement 200 wird durch das elastische Element 300 bestimmt. Dadurch ist die Empfindlichkeit bezüglich der Dynamik steuerbar. Das Ende der Drehbewegung und somit das Erreichen der Blockierposition der Blockierwippe 200 kann durch eine geometrische Gestaltung der Führungstasche bestimmt werden. Durch die unterstützende Kraft des elastischen Elements wird das Blockierelement 200 gegen die Kante 190 im Gehäusedeckel gedrückt und in ihrer Position gehalten. Die Begrenzung der Bewegung kann analog hierzu über einen anderen Ausleger beziehungsweise durch ein anderes Gestaltungsmerkmal gelöst werden.The kinematic and kinetic regulation of the blocking mechanism with the blocking
Aufgrund der fehlenden Kontaktberührung zwischen Blockierelement 200 und Zubehördeckel 150 wird das Blockierelement 200 durch die Kraft des elastischen Elements 300 in eine Drehbewegung versetzt und in die Blockierposition, ihre erste Position, überführt und dort gehalten. Bewegt der Bediener die Handhabe 180 in Richtung der Ein-Position, so wird diese vor dem Umschnapppunkt des Schlosses blockiert. Dabei trifft die Handhabe 180 auf die erste Kontur 220 der Blockierwippe 200. Das Schloss des elektrischen Schalters 100 wird vom Umschnappen abgehalten und verhindert somit eine Kontaktberührung der elektrischen Kontakte des elektrischen Schalters 100.Due to the lack of contact between the blocking
Eine denkbare Ausführung ist das Blockierelement 200 in dem Gehäuse eines Schalters zu platzieren. Durch das Übersetzungsverhältnis ist nur ein relativ kleiner Drehwinkel α für das Blockieren der Handhabe 180 und somit des Schaltschlosses nötig. Durch die günstige Positionierung der Drehachse D der Blockierwippe 200 wird bei Kontakteinleitung der Handhabe 180 auf die erste Kontur 220 der Blockierwippe 200 in Folge der Kontaktkraft ein schließendes Moment auf die Blockierwippe 200 eingeleitet. Folglich wird die Mechanik in Selbsthemmung gebracht und eine Lösung der Blockierung vermieden. Die Berührfläche des Gehäuses des elektrischen Schalters 100 am oberen Ende des Blockierelements 200 und die frühe Anschlagposition beispielsweise im Gehäuseoberteil ermöglichen ein leichtes Reseten der Mechanik. Dies wird durch die großen Hebelarme der Kontaktkraft zum Drehpunkt des Blockierelements 200 ermöglicht.A conceivable embodiment is to place the blocking
