Generic electromechanical switching devices are basically known, so it does not require a separate printed evidence for this. Usually they are used in control panels, which serve the control of electrical installations, at least partially electrically operated machines, combinations thereof or the like. The electromechanical switching devices serve in particular the activation or deactivation of electrically controllable functions, which are usually activated or deactivated by means of a control voltage in the form of a low voltage. It has become established to use predominantly rotationally actuated electromechanical switching devices for the electromechanical switching elements. As a result, on the one hand a simple handling can be achieved and on the other hand can be realized in this way a simple installation and arrangement in the control panel. The control panel can through a wall be formed, which may be formed of a metallic material, such as steel sheet or the like. But it can also be formed of a plastic, a composite material and / or the like. In addition, the control panel can also be designed as a control box or as a control cabinet and provide a closed cavity in which preferably electrical power is connected.

The switchboard usually has an opening adapted to external dimensions of the electromechanical switching device, into which the electromechanical switching device is inserted and fastened.

Operator side protrudes beyond a surface of the panel, the rotatably mounted and manually operable actuator unit so that it can be manually operated by an operator. On the other hand, the rear side projects beyond the switching unit, which is connected to electrical lines via connections of the switching unit, in order to establish or interrupt an electrical connection between two or more of the electrical lines in accordance with the respective current switching state of the electromechanical switching unit.

On the actuation side, two different embodiments are essentially to be distinguished, namely a key-operated actuating unit and, secondly, a rotary knob actuating unit. In addition, there are a variety of different configurations with respect to the switching unit and the einnehmbaren switching states.

For these different electromechanical switching elements, there are each own constructions that lead to a variety of different electromechanical switching devices and require a corresponding production-side effort.

From the US 6,274,835 B1 is an electromechanical switching device for providing an electrical connection between at least two terminals in response to a switching state due to a manual operation, wherein the electromechanical switching device is designed for placement in a control panel of an electrical control device and a rotatably mounted and manually operable actuator unit and with a the actuation unit has connectable switching unit. The switching unit provides the at least two electrical connections of the electromechanical switching device and connects them to one another depending on the electrical switching state. The switching unit has at least one displaceably mounted in a longitudinal direction of the electromechanical switching device switching element, wherein a coupling unit mechanically connecting the actuating unit and the switching unit and is adapted to transmit the manual operation of the actuating unit to the switching element of the switching unit, wherein the electromechanical switching device at least is formed by the operating unit, the coupling unit and the switching unit in a modular manner.

The invention has set itself the task of reducing the cost of an electromechanical switching unit.

With the invention, an electromechanical switching unit according to the independent claim 1 is proposed. Further advantageous developments will become apparent from the features of the dependent claims.

With the invention is particularly proposed that the electromechanical switching device comprises a coupling unit which mechanically connects the actuating unit and the switching unit, and which is adapted to transmit the manual operation of the actuating unit to the switching element of the switching unit, wherein the electromechanical switching device by at least the Actuator, the coupling unit and the switching unit is formed in a modular manner.

By means of the coupling unit is achieved that the electromechanical switching device in a modular manner from the components actuator unit, clutch unit and switching unit is almost arbitrarily combined produced. By means of the coupling unit specific, preferably standardized, connections between the coupling unit and the operating unit and the coupling unit and the switching unit can be created so that an electromechanical switching device of any kind can be assembled in a simple manner from a kit of a few components. It proves to be particularly advantageous that even the individual components, namely the coupling unit, the operating unit and the switching unit and the elements associated therewith can be used as pre-tested assemblies. As a result, the production of electromechanical switching devices can be considerably simplified, so that a variety of electromechanical switching devices can be produced as needed in the short term. With the invention, therefore, a considerable flexibility in terms of the production of electromechanical switching devices can be achieved become. In addition, the invention makes it possible to manufacture the individual components of the electromechanical switching device, namely the coupling unit, the actuating unit and the switching unit at different times separately at different locations and only then merge the electromechanical switching device when corresponding orders are present. The modules can be formed by the actuating unit, the coupling unit and the switching unit.

Especially for the regularly scheduled application in the low voltage area according to standardization, in particular the Directive 2006/95 / EC of the European Parliament and the Council of 12 December 2006 for the approximation of the laws of the member states concerning electrical equipment for use within certain voltage limits, the invention proves to be especially advantageous. As is known, special technical requirements are made of such electromechanical switching devices, which must also satisfy special tests. Despite this special effort in terms of electrical safety can be realized with the invention of the modular design, which allows a favorable production of the electromechanical switching devices.

The electromechanical switching device is typically provided as a rotationally actuated electromechanical switching device with a longitudinal axis, which usually also represents an axis of rotation with respect to the rotatable mounting of an actuating element of the actuating unit at the same time. With special designs, the axes can also differ from each other. Usually, the electromechanical switching device is divided into two areas from the point of view of electrical safety, namely an area for manual operation which is sufficiently electrically insulated from an electrically active area which provides the actual switching function in accordance with the switching state of the electromechanical switching device. The switching unit puts over it In addition, usually also the connections ready, between which the electrical connection is made or interrupted according to the respective switching state. Due to this construction, the operating area usually protrudes from the control panel, whereas the active area is separated from the operating area by the control panel, in particular with respect to electrical safety and electrical insulation, in particular shielded.

The coupling unit preferably represents a connection region, which is correspondingly coupled in rotation with the actuating unit for transmitting a rotational movement of the actuating unit. For example, the connection can be made in that the coupling unit has a coded receptacle for a correspondingly opposite coded projection of the actuating element, so that between both a rotationally fixed connection can be achieved. However, it can also be provided that a latching element of the actuating unit engages in a latching receptacle of the coupling unit in order to produce the rotary connection.

The coupling unit is further provided for converting the rotational movement, which is introduced by means of the actuating element into the coupling unit, into a translational movement and correspondingly displacing the switching element of the switching unit in a translatory manner. This allows the switching element to realize the desired switching state. Corresponding to the respective rotational positions of the actuating element, corresponding axial positions of the switching element thus result. Corresponding to the respective positions of the switching element with respect to the respective switching states, contacts connected to the terminals of the switching unit are respectively connected. As a result, a plurality of switching functions can be realized with only a few components in the desired manner by means of the electromechanical switching device according to the invention.

The switching element itself may, for example, be guided in an axially sliding manner and have one or more electrically conductive regions by means of which electrical connections can be made or interrupted between contacts of the switching unit.

According to an advantageous development, it is proposed that the coupling unit has a rotational angle limiting disc which has at least one rotational angle limiting element. Preferably, the rotational angle limiting disc is arranged in the connecting region between the coupling unit and the actuating unit. With the rotation angle limiting disk, a rotation angle of the actuating element can be set in a predeterminable manner. For example, the rotation angle can be limited to 90 degrees. In addition, the rotation angle can be limited to 45 degrees. Advantageously, the rotation angle limiting disk is designed to be able to limit a plurality of rotation angles. By appropriate adjustment or assembly of the rotational angle limiting disc can be achieved that a respective limiting angle with respect to a manual actuation of the actuating unit can be adjusted. The rotation angle limiting elements can be formed, for example, by recesses, in particular openings, in the rotation angle limiting disk. The recess preferably extends over a rotation angle range, which allows a setting range over the desired rotation angle.

According to a further development, it is proposed that the rotation angle limiting disc is arranged rotationally fixed relative to the switching unit. Particularly advantageously, the rotation angle limiting disc is connected to the switching unit via the coupling unit. This makes it possible to set the permissible angle of rotation with respect to the switching unit as a reference point.

An embodiment according to the invention proposes that the coupling unit has a crank element acting together with a crown element. By this configuration, it is easily possible to convert the rotary actuator of the actuator into an axial movement, which acts on the switching element. At the same time it can be provided that the crown element is rotatably connected to the link element, wherein the crown element is arranged axially movable and cooperates with a rotatably fixed in a rosette and fixed in the longitudinal direction of the electromechanical switching device arranged shelf to provide the desired locking and / or tactile functions , The link element preferably provides a link which acts on the switching element and converts a rotational movement into an axial movement of the switching element. Preferably, therefore, the link element is rotatably mounted and rotatably connected to a rotational axis of the actuating unit. As a result, the rotational movement of the actuating unit can act directly on the link element. In this way, a simple, easy-to-use arrangement can be achieved.

In addition, it is proposed that the crown element is rotatably mounted with the link element and slidably mounted in the longitudinal direction of the electromechanical switching device in the link element. This makes it possible, in cooperation with the link element to convert a rotary actuator of the actuating unit in a longitudinal movement and to act on the switching device. For this purpose, the switching element preferably has at least one contact region which cooperates with the backdrop provided by the link element. The displaceable mounting of the crown element in the gate element makes it possible for a crown gate facing the shelf to interact with the shelf and thereby provide desired mechanical functions such as detents, buttons and / or the like. For example, one or more bearing points for the crown element can be provided in the link element for this purpose.

It proves particularly advantageous if the crown element is biased in the direction of the shelf. On the one hand, this ensures that the crown element is permanently in engagement with the shelf, regardless of a rotational position of the actuating element.

Furthermore, it is proposed that the coupling unit has a modular construction, in particular as a separate module in each case with a crown element, a link element and a spring. With the modular structure, it is possible to create the electromechanical switching device as needed in a variety of functional configurations in a simple and flexible manner. The modules may be formed by elements of the coupling unit. Thereby, the basic mechanical structure of the electromechanical switching device can be maintained substantially independent of the modules used.

According to a further embodiment, it is proposed that the crown element and / or the link element are arranged interchangeably in the coupling unit. This embodiment makes it possible to retrofit an electromechanical switching device with another function. For this purpose, the crown element and / or the link element can then be easily replaced. Preferably, standardized dimensions for the crown element and / or the gate element are provided so that they can be easily exchanged in the coupling unit at will.

In this first exemplary embodiment, the electromechanical switching device 10 has a rotatably mounted and manually operable actuating unit 46 in the form of a key-operated lock 46. Furthermore, the electromechanical switching device 10 has a switching unit 14 that can be connected to the lock 46, which in the present case provides two electrical connections 62 of the electromechanical switching device 10 and electrically interconnects them depending on the electrical switching state and the switching element displaceably mounted in a longitudinal direction 16 of the electromechanical switching device 10 18 ( FIG. 4 ) having. The switching unit 14 is designed to assume the switching state as a function of the operation of the lock 46.

Furthermore, the electromechanical switching device 10 according to FIG FIG. 1 a coupling unit 20, which mechanically connects the lock 46 and the switching unit 14 with each other. The coupling unit 20 is further configured to transmit the manual operation of the lock 46 to the switching element 18 of the switching unit 14.

From the 1 and 2 is already an essential aspect of the invention can be seen, namely the modular principle of the electromechanical switching device 10. Both variants of the electromechanical switching device 10 according to the 1 and 2 Basically based on a similar structure. This is based on FIG. 3 and FIG. 4 further clarified.

FIG. 3 shows in a perspective-schematic exploded view of the electromechanical switching device 10 according to FIG. 1 with optional embodiments for the coupling unit 20. In the present case, the lock 46 in a sleeve 50th arranged rotationally fixed. The lock 46 includes a rotatably mounted unspecified lock cylinder which can be rotatably actuated upon insertion of a mating key, that is, a key with a corresponding key secret. The front side of the lock cylinder is surrounded by a display plate 52 which is axially supported in the longitudinal direction 16 of the electromechanical switching device 10 between the sleeve 50 and the lock 46.

On a display disc 52 opposite end face of the lock 46, a stop plate 22 is arranged, by means of which a rotation angle for the manual operation of the lock 46 can be limited or adjusted. In this respect, the stop disc 22 forms a rotation angle limiting unit.

The operation can for example be done either by a handle in the form of the rotary knob or by a key operation of a castle. Each of these elements is connected to the corresponding link element either non-positively or positively.

The link element serves to convert the rotational movement into a translational movement with respect to the slide. Accordingly, the rotational movement is transmitted to the slide 18 by means of a link of the link element. Furthermore, the crown element is mounted longitudinally displaceable in direction 16 in the link element. At the same time it is rotatably connected to the link element, so that the crown element follows a rotational movement of the link element. The crown element has a crown on which a shelf 58 faces. The shelf 58 is rotationally fixed and arranged in the longitudinal direction 16 fixed in the rosette 54. Due to a bias by the spring 48, the Kronenkulisse is located on an unspecified projection of the shelf 58 at.
