Definitions

  • the invention relates to a rotary drive for an electrical switch, which comprises a rosette, a rotatable link and a slide.
  • Such rotary actuators are available on the electrical market for low-voltage switching devices and are part of the prior art.
  • a slider is extended by rotating a toggle in front of the front panel in the axial direction, which actuates a switching element on the rear of the switch.
  • the rotary actuator is designed with a knob or lock as a handle with a grid or button function. The reset of the rotary drive when the handle is released is effected by spring force in the axial direction on the slide.
  • the invention has for its object to provide an electrical switch of the above type, in which the locking takes place via the torsion spring.
  • the object is achieved by a switch with the features according to claim 1.
  • An embodiment in which the torsion spring has at least one circular turn and the two spring ends have the circular shape tangentially or on a radius to the outside up to a certain distance proves to be particularly advantageous leave, then turned in opposite directions and end up as two pieces of wire running parallel to the torsion spring axis.
  • FIG. 1 shows an exploded view of the rotary drive 1 according to the invention, which comprises a rosette 2, two slides 4, a link 3, a torsion spring 5, a cover 9, a seal 15, a front ring 16 and a toggle 17.
  • the illustration shows the installation position of the components mentioned.
  • the torsion spring 5 consists of several adjacent turns 12 of the same diameter. Both ends 6, 7 of the torsion spring 5 leave the diameter tangentially or on a radius to the outside up to a certain distance, are then bent in opposite directions at right angles and end up as two straight pieces of wire running parallel to the winding axis at the same height.
  • the windings 12 of the torsion spring 5 enclose, with little play, an inner guide formed by the cover 9, which, however, can also be provided by the link 3, in which the torsion spring 5 is mounted concentrically.
  • the rosette 2 shows a cross-sectional view of the position of the torsion spring 5 in the unactuated zero position and in the position locked over the spring end 7.
  • the rosette 2 has a largely ring-shaped surface with a step-shaped shoulder 10 and an area 19 with a diameter reduction, which is delimited by two radially extending transitions 18 to the shoulder 10, on each side of which a latching catch 11 in the step-shaped shoulder 10 at the same angular distance lies.
  • the backdrop 3 is largely arranged within the rosette 2 and carries the torsion spring 5 within the end region which is designed in the form of an annulus and faces the knob 17.
  • the annular end region is provided with two cutouts 14 at the same angular distance as the above-mentioned transitions 18 of this type. that also radially extending transitions 20 of the cutouts 14 are in overlap with the above-mentioned transitions 18 of the rosette 2 in the zero position of the rotary drive.
  • a concentric outer guide with a corresponding diameter clamps the spring ends 6,7 projecting like wings inwards.
  • the outer guide is axially divided in two at half the height of the spring, into the fixed part formed as a shoulder 10 of the rose 2 and the part which can be rotated as a circular end region of the link 3 and which is connected to the knob 17 as a handle.
  • the aforementioned latch 11 is provided to achieve the "latching" function. Due to the pretension of the spring ends 6, 7, which is reinforced by the "opening" actuation, the deflected spring end 7 snaps into the cases which are congruent in the end position, i.e. in the latch 11 of the rosette 2 and in the cutout 14 of the backdrop 3. This reliably blocks the return because the locking stability increases with the spring tension.
  • the torsion spring 5 can be deflected in one as well as in two directions in order to achieve a two-position drive.
  • the torsion spring 5 is deflected in the opposite direction to the direction described above, only the functions of the spring ends 6, 7 are interchanged due to the completely symmetrical structure, ie the spring end 7 lies firmly against the transition 18 of the rosette 2, and the spring end 6 is through the backdrop 3 taken away.
  • the latching can be canceled by inserting appropriately shaped filler pieces into the latching latches 11. Filling pieces of this type can also be used to limit the rotation, so that all rotary drive variants are possible.
  • the described embodiment according to the invention with appropriate dimensioning and arrangement of the torsion spring 5, has a large free cross section 13, which is determined only by the predetermined outer diameter and the required wall thicknesses of the rosette 2 and the backdrop 3.
  • the realization of illuminable rotary drives has been significantly improved since there is now enough space available for the lamp and its replacement.
  • FIG. 3 an elevation of the rotary drive 1 is shown in perspective, which shows the arrangement of the aforementioned components to each other.
  • the torsion spring 5 is here in the latching position, because its spring end 6 or 7, which is in the cutout 14, projects on the underside beyond the outer edge of the link 3, where the part of the rosette 2 (not shown here) with the latching latch 11 (see FIG. 2) lies.
