Definitions

  • the invention relates to an electrical installation device comprising an electronic circuit module for actuating or switching and/or dimming consumers, which has at least one microswitch.
  • Electrical installation devices such as flush-mounted switches or dimmers, which are primarily intended for switching corresponding consumers, are well known.
  • Known electrical installation devices can be found in the documents, for example EP 2 492 940 A1 , EP 2 743 953 A1 , EP 2 194 552 A2 , WO 2012/010226 A1 , DE 195 44 769 A1 and US 2010/0101924 A1 be removed.
  • such installation devices have a switching contact that can switch a consumer connected to it, for example a lamp. To do this, simply switching the switching contact opens or closes the circuit.
  • Microswitches are also used to open or close the circuit, the contacts of which are usually less than 3mm apart when open.
  • the stroke that such microswitches have when actuated is correspondingly small. This is so low that a user experiences little to no haptic feedback when pressing the switch. This lack of feedback may be desirable or not disadvantageous in certain applications, such as digital controls, while it may be undesirable in other applications, such as classic light switches on walls.
  • light switches are often designed as toggle switches with a rocker switch that can be moved or tilted into two different switching positions. The switches can remain in the respective switched position until they are pressed again.
  • microswitches Due to the aforementioned small stroke of microswitches, the mechanics used to operate the microswitch must be precisely coordinated. Therefore, the mechanisms for operating the microswitches are often not suitable for additionally holding the rocker switch in the corresponding switching position.
  • the installation device comprises at least one rocker switch for actuating a microswitch, which can be moved into one of two switching positions when actuated via an operating stroke, the microswitch having a switching stroke that is many times smaller than the operating stroke of the rocker switch, a transmission device for Transmitting a movement of the rocker switch to the microswitch, and a snap device that forces the rocker switch into one of the two switching positions.
  • the transmission device is provided, which transmits the movement of the rocker switch to the microswitch and switches it, the transmission device having a resilient arm with a link guide.
  • the large operating stroke of the rocker switch is provided so that a user experiences haptic feedback when operating the microswitch.
  • the snap device forces the Rocker switch when pressed into its corresponding switching position, so that the user can feel the rocker switch tipping as it transitions from one switching position to the other.
  • the snap device also forces the rocker switch to remain in the respective switching position until it is actuated again.
  • the snap device is designed in such a way that the user registers or feels the actuation of the rocker switch as haptic feedback, for example as a kind of “click”.
  • the installation device according to the invention can therefore use the advantages of a microswitch, but at the same time retains the switching feeling of a classic mechanical light switch.
  • the snap device and the transmission device can be spatially separated from one another or combined with one another.
  • the snap device can act directly on the microswitch, with the transmission device both transmitting the movement of the rocker switch to the microswitch and also ensuring that the rocker switch is forced into one of the two switching positions.
  • the snap device and the transmission device are designed to be spatially separated from one another. Since the microswitch has a comparatively small switching stroke, the transmission device must switch precisely. It can therefore be advantageous if the snap device is designed to be spatially separated from the transmission device, so that these two different mechanisms do not interfere with each other and can each be designed to be optimized for their function. For example, the microswitch can be switched precisely and comparatively gently, while the snap device can force the switching rocker to overcome resistance with appropriate effort.
  • the snap device has a leaf spring and a link guide.
  • the link guide can be formed, for example, by a projection or a recess, a groove, one or more webs or the like on a base.
  • the linkage it would also be conceivable for the linkage to be designed as a sequence of projections and recesses.
  • the leaf spring can be biased against the base, so that the link guide or at least parts of it form a resistance that the leaf spring must overcome. By overcoming resistance in this way when operating the rocker switch, the desired haptic feedback can be made possible. The user can feel at which point the leaf spring overcomes a dead center, for example the highest point of a projection, and thus slips from one switching position to the other.
  • the link guide for designing the switch can also be designed in such a way that the rocker switch is held in the corresponding switching position.
  • the snap device has a spiral spring and a link guide.
  • the link guide can be designed as a projection and/or recess on a base. It would also be possible for the link guide to have a groove, a web or a slot in which the spiral spring is guided.
  • the function of the coil spring in the snap device is essentially the same as that of the leaf spring.
  • the spiral spring is additionally assigned a sleeve which surrounds the spiral spring at least in sections.
  • the sleeve can be designed in such a way that that end of the spiral spring that faces the link guide is arranged within the sleeve, so that the sleeve is guided by the link guide when the rocker switch is actuated.
  • one can Sleeve can also be better pressed against the link guide in order to force the rocker switch into one of two switching positions when actuated.
  • the transmission device has a resilient arm with a link guide.
  • the resilient arm serves as the element that operates the microswitch, i.e. when the rocker switch is actuated it is moved so far in the direction of the microswitch that the resilient arm can switch the microswitch.
  • the link guide can be designed on the resilient arm, while the switching rocker can have a projection, a nose, a prong, a pin or similar, which is guided along the link guide when switching and thereby moves the resilient arm from its rest position.
  • the link guide can be designed in such a way that the resilient arm moves away from the microswitch again after switching and returns to its starting position (tactile function).
  • the link guide it would also be possible for the link guide to be designed in such a way that the resilient arm is pressed onto the microswitch when switching until a user activates the rocker switch again and the resilient arm thus moves away from the microswitch again (switching function).
  • the transmission device has a leaf spring.
  • the rocker switch can have a projection, a nose, a prong, a pin or something similar in order to move the leaf spring out of its rest position when it is actuated, so that it snaps and thereby activates the microswitch.
  • the transmission device could also be designed in such a way that the leaf spring switches the microswitch every time it is actuated releases again, as well as the leaf spring actuating the microswitch and remaining in the switched position until the rocker switch is actuated again.
  • a further embodiment provides that the transmission device has a resilient arm and a leaf spring.
  • the leaf spring can be arranged between the resilient arm and the rocker switch, so that the movement of the rocker switch is transmitted via the leaf spring to the resilient arm in order to ultimately actuate the microswitch.
  • the circuit module can be actuated both wirelessly, for example via Bluetooth or WLAN, and via the microswitch.
  • This embodiment has proven to be particularly advantageous as the demand for intelligent or digital solutions for building technology is constantly growing. A user can operate a light switch either manually or via a remote control or an app on a cell phone or tablet.
  • Fig. 1 shows part 10 of an installation device.
  • the installation device includes, among other things, an electronic circuit module (not shown) with at least one microswitch 22, a rocker switch (not shown) for actuating the installation device, a transmission device 18, a snap device 30 and a housing (not shown). Furthermore, the installation device has a rocker element 12, on which the switching rocker is arranged, a suspension 11 for the rocker element 12 (cf. Fig. 1 ) and a carrier 14.
  • the rocker element 12 is connected to the rocker switch in a known manner in such a way that when the rocker switch is actuated, the rocker element 12 moves in accordance with the movement of the rocker switch.
  • the installation device is designed so that it can be used in standard flush-mounted boxes or surface-mounted inserts.
  • the rocker element 12 is mounted on the carrier 14 so that it can be tilted about an axis A.
  • the carrier 14 has a base 16 for the transmission device 18 or the snap device 30, which is detailed in the following figures are shown.
  • a microswitch 22 is also arranged below the rocker element 12 or the carrier 14 (see Fig. 5 ), which can be switched by pressing the rocker switch.
  • a first embodiment of the transmission device 18 is in Fig. 2 , 3A and 7 to see.
  • the rocker element 12 has a tapered projection 24, the tip of the projection 24 lying in a plane with the axis A.
  • the carrier 14 has a spring arm 26, which in turn has a bulge 28 with two side surfaces 28a and 28b (see Fig. 3A ).
  • the spring arm 26 is arranged immediately below the projection 24, so that the projection 24 slides on the spring arm 26 when the rocker element 12 is actuated.
  • the tip of the projection 24 moves in the direction of the bulge 28 or along the side surface 28a, so that the projection 24 presses against the spring arm 26 and thus moves it downwards, away from the rocker element 12, until the projection 24 reaches the tip of the bulge reached 28.
  • the projection 24 can slide down on the opposite side surface 28b, whereby the spring arm 26 can move back towards the rocker element 12.
  • the microswitch 22 not shown, is arranged directly below the spring arm 26, the microswitch 22 can be actuated by the up-and-down movement of the spring arm 26.
  • FIG. 3B Another embodiment of the transmission device 18, which is based essentially on the same principle as the embodiment of Fig. 2 and 3A is in Fig. 3B shown.
  • the difference here lies in the design of the bulge 28.
  • the side surfaces 28a and 28b are arranged at an obtuse angle to one another, so that there is no tip over which the projection 24 slides when the rocker switch or the rocker element 12 is actuated could. If the rocker switch is actuated, the projection 24 moves along the side surface 28a and presses the spring arm 26 downwards in the direction of the microswitch 22.
  • the projection 24 then comes to rest on the side surface 28b, which is parallel to the spring arm 26, so that the spring arm 26 is so long remains pressed down until the rocker switch 12 is actuated again and the projection 24 slides again over the side surface 28a next to the bulge 28.
  • the projection 24 moves along the side surface 28a onto the side surface 28b and comes to rest on it.
  • the spring arm 26 remains pressed downwards and thus also holds the microswitch 22 in a switched position.
  • the spring arm 26 can return to its starting position so that the microswitch 22 is released, thereby achieving the function of a switch.
  • a resistance-free switching stroke of less than 3 millimeters is sufficient to actuate the microswitch 22, which is why the transmission devices 18 shown provide little to no haptic feedback to the user when the rocker switch 12 is actuated.
  • the transmission devices 18 shown provide little to no haptic feedback to the user when the rocker switch 12 is actuated.
  • the snap device 30 according to the invention is provided in the arrangement of the installation device, which is in connection with the Fig. 5 to 9 will now be explained in more detail.
  • At least part of the snap device 30 or its link guide can be mounted on the carrier 14 with a resilient part of the transmission device 18 (see, for example, leaf spring 32 in Fig. 5 ) be trained. Also in the embodiments of the transmission device 18 according to Figs. 2 to 3B In principle, it is conceivable that parts of the snap device 30 are formed on the same carrier 14 as the spring arm 26.
  • the link guide could also be provided on its own support in the installation device.
  • the example of the transmission device 18 in Fig. 5 shows a common carrier 14 'for a leaf spring 32, which represents a resilient element of the transmission device 18 (see Fig. 5 ), and a web 34, which serves as an obstacle for a spring 36, in particular a leaf spring 36, of the snap device 30.
  • the carrier 14 ' can be arranged between the rocker element 12 and the carrier 14, which carries the spring arm 26.
  • the example shown of the transmission device 18 includes the projection 24, which is formed on the rocker element 12, a leaf spring 32, which is formed on the carrier 14 ', and the spring arm 26, which is provided on the carrier 14. Accordingly, when the rocker switch is actuated, the projection 24 can slide over the leaf spring 32, so that it is pressed downwards towards the spring arm 26 and thus also pushes it downwards, so that the microswitch 22 is actuated.
  • the projection 24 can be relative to the Leaf spring 32 must be aligned so that the leaf spring 32 snaps back into its starting position after each actuation of the rocker switch, or that it remains pressed down until the rocker switch is actuated again and thus releases the leaf spring 32.
  • the snap device 30 is used in the example Fig. 5 composed of a leaf spring 36, which is attached to the rocker element 12, and a web 36, which is formed on the carrier 14 '.
  • the leaf spring 36 is here - similar to the projection 24 in the previously described transmission device 18 - designed and arranged in such a way that it must slide over the web 34 when the rocker switch is actuated. This initially leads to the web 34 forming a resistance, so that force must be used to push the tensioned leaf spring 36 over the web 34. As soon as this force is reached or overcome and the leaf spring 36 jumps over the web 34, this can be felt and heard by the user as a “click”. The user therefore feels that he has just activated the rocker switch, analogous to the feel that conventional mechanical light switches have. In this way, the user can be given a good, familiar switching feeling, while at the same time only one microswitch 22 is required for the actual switching of the consumer.
  • the snap device 30 also serves to hold the rocker switch or the rocker element 12 in the respective switched position. It can only move back into the other position when the rocker switch is actuated by a user.
  • the leaf spring 36 simply needs to be pretensioned relative to the web 34 so that it cannot overcome the web 34 on its own without external force.
  • the web 34 therefore also serves as a boundary between the switching positions.
  • FIG Figs. 6 and 7 Another embodiment of the transmission device, in which a leaf spring 36 is used, is shown in FIG Figs. 6 and 7 shown. Since this leaf spring 36 is of the same design as that used in the previously described snap device, the same reference number is also used.
  • a leaf spring 36 is attached to the rocker element 12. Similar to the embodiment of Fig. 3B When the rocker switch is actuated, the leaf spring 36 slips onto a projection 38 which is formed on a spring arm 40, so that the spring arm 40 is pushed downwards and thus actuates a microswitch 22 located underneath (not shown).
  • the snap device 30 includes a spiral spring 42, the front end of which is guided in a sleeve 44. Furthermore, a link guide with projections and recesses 48, 46 is provided, which on average are in Fig. 9 you can see.
  • the spiral spring 42 essentially takes on the same functions as the leaf spring 36 from the exemplary embodiments Figs. 6 and 7 .
  • the spiral spring 42 is biased against the carrier 14, on which the projections and recesses 48, 46 are formed, in such a way that it forces the switching rocker to remain in the respective switched position.
  • the sleeve 44 surrounds the spiral spring 42 at least on the side facing the projections and recesses 48, 46. This allows the spiral spring 42 to be inside the Sleeve 44 are guided so that the sleeve 44 serves as a contact surface between the spiral spring 42 and the projections and recesses 48, 46.
  • the sleeve 44 has also proven to be advantageous when fixing the rocker switch in the respective switching position. Due to the larger contact surface of the sleeve 44 compared to the pure spiral spring 42, the sleeve 44 is better held in the corresponding recess 46 and thus in the respective switching position.
  • the material of the sleeve 44 or its surface can be designed accordingly in order to increase the static friction between the sleeve 44 and the projections or recesses 48, 46.
  • a spring arm 26 or a leaf spring 32 for the transmission device 18 is arranged on the same carrier 14 as the projections and recesses 48, 46.
  • Such a spring arm 26 is also in the perspective view of Fig. 8 to see.
  • FIG. 4 A non-inventive embodiment of the snap device 30 in an installation device is shown in Fig. 4 shown, wherein in this embodiment the transmission device and the snap device are integrated.
  • the snap device 30 includes a spiral spring 42, the front end of which is guided in a sleeve 44.
  • the upper microswitch 22 serves as a link guide for the front end of the sleeve 44
  • Actuating element is dome-shaped, so that when the rocker switch 12 is actuated, on the one hand, the microswitch 22 is actuated, but on the other hand, after actuating the microswitch 22, the sleeve 44 slides over the dome-shaped actuating part of the microswitch and thereby induces the desired snap movement or the desired tactile feedback gives.
