- the rotary switch is rotatably mounted in the switching unit, wherein it is also axially limited.
- the housing part has a recess into which the rotary knob is at least partially inserted, in particular, in which the sleeve portion of the knob is at least partially inserted, in particular and is rotatably mounted.
- Switching unit is made possible through the housing wall.
- one on the connecting part in particular an am
- Hollow shaft portion of the connecting part arranged locking lug engaged in a recess of the sleeve portion, in particular for non-rotatable connection of the connecting part with the knob.
- the advantage here is that a simple connection is achieved and the locking takes place during axial insertion.
- Dismantling is also possible if the locking lug is bent back radially, that is pressed out of the latching lug receiving recess.
- Labyrinth seal arranged, in particular wherein the knob has an annular groove and at least one of the groove walls of the annular groove projects into an annular groove of the housing part at least partially.
- knob and the connecting part are each made as a one-piece, so one-piece, plastic injection molded part.
- the advantage here is that a simple production is possible.
- knob is slidably mounted on the housing part.
- the advantage here is that no further components are necessary.
- a sealing ring is arranged on the sleeve portion of the knob, which rests in an annular recess of the housing part, in particular wherein the contact surface between the sealing ring and sleeve portion has a constant radial distance from the sleeve axis, ie in particular only in the axial direction and in the circumferential direction extends ,
- the sealing ring is attachable to the sleeve portion and thus a simple assembly is executable.
- the connecting part on a disc-like portion which presses against the sealing ring in particular wherein the normal direction of the pressing on the sealing ring pressure surface is aligned on the disc-like portion in the axial direction.
- the advantage here is that an axial circlip is not necessary.
- the connecting part has a polygon section, cross section or eccentrically shaped section which is at least partially introduced into the receiving recess of the switching unit.
- Section is arrangeable. Thus, a non-rotatable and preferably backlash-free connection is possible.
- the sealing ring is arranged axially between the locking lug and the disc-like portion.
- the radial extent of the disk-like portion has a maximum as a function of the circumferential angle, in particular which is used as an assembly display aid.
- the sealing ring is axially deformed so strongly
- the advantage here is that the sealing ring is protected against excessive deformation.
- FIG. 1 an electrical appliance, in particular an inverter, is shown in plan view.
- FIG. 2 shows a sectional view.
- a switching unit 1 of the device with connection part 2 and knob 3 is shown in exploded view from a first viewing direction, wherein the housing is omitted.
- FIG. 5 shows a switching unit 1 of the device with connection part 2 and rotary knob 3 in an exploded view from a different viewing direction than in FIG.
- an upper part 5 which is preferably made of plastic, placed on a lower part, which is preferably made of metal, such as aluminum, and having cooling ribs and / or cold fingers.
- the arranged in the device power electronics is thermally conductively connected to the lower part, so that the heat generated by the power electronics via the lower part can be discharged to the environment.
- the signal electronics is provided on a printed circuit board 20, which is connected to the upper part 5, in particular screw-connected or clips connected or engaged.
- outside input means are arranged, with which parameters stored in the signal electronics can be changed.
- a rotary knob 3 is provided which is non-rotatably connected, in particular by means of non-positive connection and / or snap-in connection, with a connecting part 2, which in turn rotatably with its driver portion 41, which is preferably formed cross-shaped, inserted into a corresponding receiving recess 50 and thus form-fitting connected is.
- the knob 3 is guided with its sleeve-shaped extension through a recess in the wall of the upper part 5, that is, the housing of the upper part 5.
- a sealing ring 21 in particular O-ring made of rubber, is arranged.
- This sealing ring 21 thus touches the sleeve-like extension in the circumferential direction continuously and has a larger radial distance than the sleeve-like extension, since it is arranged on the radial outer side.
- the sealing ring 21 is located in a recess of the housing, so the upper part 5 and is thus limited against the axial direction. Because the recess forms for the sealing ring 21 a contact surface portion whose normal is aligned in the axial direction.
- the sleeve-like extension of the rotary knob 3 receives a hollow shaft portion of the connecting part 2, wherein this hollow shaft portion also has an axial slot to improve the deformability in the radial direction.
- the connecting part 2 has axially spaced from the sealing ring 21 on two locking lugs, which are engaged in recesses 40, in particular holes, wherein the recesses are arranged in the sleeve-like extension.
- the sleeve-like extension is axially spaced from the sealing ring 21 on two locking lugs, which are engaged in recesses 40, in particular holes, wherein the recesses are arranged in the sleeve-like extension.
- the sleeve-like extension is axially spaced from the sealing ring 21 on two locking lugs, which are engaged in recesses 40, in particular holes, wherein the recesses are arranged in the sleeve-like extension.
- the sleeve-like extension is axially spaced from the sealing ring 21 on two locking lugs, which are engaged in recesses 40, in particular holes, wherein the recesses are arranged in the sleeve-like extension.
- the connecting part 2 has an axial region adjoining the axial region covered by the sealing ring 21, in which a disc-like section of the
- Connecting parts 2 is formed.
- the connecting part 2 is radially further expanded in this area than the largest radial distance of the sealing ring 21st
- Section of the connecting part 2 is slidably mounted on the housing during the rotational movement of the Knob 3, which is also slidably mounted on the housing, ie upper part 5.
- the housing axially on both sides of a bearing surface for a sliding bearing.
- a labyrinth seal 32 is arranged in particular in the region of the sliding bearing of the rotary knob 3, which is formed by means of the housing facing side of the knob 3 formed annular grooves, one arranged between two annular grooves, axially formed on the knob 3 to the housing out and protruding annular wall projects into a corresponding annular groove of the housing at least partially.
- annular wall formed on the housing projects at least partially into one of the annular grooves of the rotary knob 2.
- labyrinth seal 32 seals, but the sealing ring 21 is provided as a further seal to increase the sealing safety
- the hollow shaft section 34 also presses outwardly in the radial direction and is thus connected in a force-locking manner to the sleeve section 33.
- the radial extent of the disk-like extension is different in the circumferential direction.
- a mounting orientation indicating portion 4 is formed so that the mounting orientation is made clear.
- the switching unit 1 is electrically connected to its electrical connection elements 42 connected to conductor tracks of the printed circuit board 20 and thus mechanically held by the printed circuit board 20.
- the printed circuit board 20 is in turn screw-connected to the upper part 5.
- the switching unit 1 connects depending on the angular position of the rotatably received in the receiving recess 50 connecting part 2 different electrical lines together.
