Definitions

  • the invention relates to an electrical switching device, in particular Key switch, with an actuator, z. B. rocker switch, that returns to its original position after actuation, with a slide acted upon by at least a pendulum hinged to it and with one Switching element that works with the slide and with the pendulum and for actuating at least one contact arrangement serves.
  • Electrical switching devices are known whose actuating elements, for example, seesaws, always after switching return to their starting position. The keep switching components acted upon by the actuating element in the relevant switching device the respective switching position up to next actuation unchanged at.
  • the advantage of such Design of an electrical switching device is in that the overall aesthetic impression of the switching device is not is affected by different inclinations of the actuating element, because this is always the same position in the rest position occupies.
  • a swivel part is rotatably mounted, the both journals each have a flat, on which Spring bars resemble leaf springs and the swivel part in a center position. Furthermore, the swivel part with two pressure pieces arranged symmetrically to each other provided that work with the rocker switch by this in each case from a corner of the Swinging part molded bearing surface is applied.
  • the constructive inclination of the rocker switch opposite the pivoting part leads to the fact that only one of the two contact surfaces each pressure piece engages with the rocker switch comes, so that with each shift actuation the rocker switch the swivel part is loaded into the other position becomes.
  • a similar switching device in which also the movement of the actuator from a slide with a beveled Printing area and at least one pendulum arranged thereon executes a transverse movement and thereby also a swiveling movement Switching element is on the market as a button known.
  • the at least one pivotable pendulum arranged on the slide is in the form of an isosceles triangle, the designed as a swivel axis near the corner point
  • the pendulum's axis of symmetry intersects and in lateral bearing points is guided in the slide.
  • the switching element takes an inclined position in relation to the pendulum, so that depending on the respective switching position, the pendulum at Actuation with one of the two other corner points against the Slider bumps, experiences a certain deflection and the Brings slider into its other position.
  • One on Compression-supporting compression spring ensures that the pendulum in Always a middle position between the two deflection positions occupies.
  • the pendulum is integrally connected to the slide, that the articulated connection of the pendulum with the Slider is web-like and has a connection cross section has, which is dimensioned so that taking advantage of the elasticity of the material used to reset the pendulum required restoring force results when the pendulum is deflected.
  • this can easily by changing the cross section of the pendulum to the Slider can be varied between strong and weak resetting.
  • Pendulum and the slide are made of plastic. This makes possible an inexpensive series production with simultaneous Exploitation of weight advantages over manufacturing made of metal.
  • a special embodiment is characterized in that as a hinged connection of the pendulum with the slide a film hinge is provided.
  • two pendulums can be provided be symmetrical to the longitudinal axis of the slide at a distance are arranged to each other.
  • the pendulum is expediently designed as a flat part that of the end facing away from the articulated connection or formations are provided, which with the switching element work together to apply it.
  • Fig. 1 is a partial longitudinal section through an inventive Switching device 10 with a base upper part 12, in which a switching element 14 is pivotally mounted and with a slide 16 cooperates, which is in operative connection with an actuating element 18 via a nose 19 molded thereon with a molded on the slider 16 switch 17 in operative connection stands.
  • Pendulum 20 On the slider 16 is also a triangular, generally as Pendulum 20 designated pivot part, which is the movement the slide 16 transferred to the switching element 14, which in turn a contact assembly 22 actuates a fixed contact piece 24 and a movable contact piece 26 which is pivotally supported on a contact carrier 28 and by the 1 in the closed position shown in Fig. 2 Open position is pivotable.
  • the switching element 14, its known pivot bearing here is not shown in detail and which is the movable contact piece 26 loaded with a spring sleeve against the contact carrier 28, has one at its end facing away from the contact arrangement 22 arranged transversely to its longitudinal axis, penetrating the switching element Recess 15, which penetrated by the slider 16 which in turn is acted upon by a return spring 30, occupies the rest position shown in Fig. 1.
  • the pendulum 20 which is similar to an isosceles triangle is integral with the via a small connecting web 21 Slider 16 connected.
  • This web-like connection serves 21 of the pendulum 20 with the slider 16 simultaneously as a swivel joint for the pendulum, the pivot path of the pendulum 20 on the one hand and the restoring force resulting from its deflection on the other hand both from the elasticity of the used Material as well as from the design cross section of the connecting web 21 are determined.
  • Pendulum 20 engages with its upper half of symmetry 32 a molded on the switching element 14 switching web 34, which is the upper Limitation of the recess 15 forms, engages and transmits so the displacement of the slide 16 on the switching element 14, the thereupon around itself with the central axis of the slide 16 intersecting axis of rotation pivots counterclockwise.
  • the switching element 14 After reaching the end position of the slide shown in Fig. 2 16, the switching element 14 assumes the switching position according to FIG. 2, in which, on the basis of the exposure thus caused, the Contact arrangement 22 is open.
  • the main advantage of the present invention results from the fact that on the one hand the production of the invention Switchgear is significantly simplified because fewer parts too are mounted and secondly what is more meaningful Interference due to excessive friction due to Contamination by dust the pendulum's pivoting mobility 20 do not affect, since the pendulum in one piece on the Slider 16 is molded.
  • the Connection cross section in the form of a web 21 it is also possible adjust the restoring force of the pendulum 20.
  • connection cross-section is either above or below the end section designed here as a flat web of the web 16, to which the pendulum 20 then connects at an angle or the spring action results from torsion of the face of the section of the end section shown here of the pendulum 16 connecting connecting web.
  • the angle between the direction of movement of the slider 16 and the middle position of the switching element 14 is in the shown Example 90 °.
  • angles are between 0 ° and ⁇ 90 °, which means that the to be actuated contact point 22 between the slider 16 and the Actuator 18 is arranged so that the switching element is directed almost upwards, that is to the actuation side out.
