Definitions

  • the invention relates to a switching device according to the preamble of the claim 1.
  • Switching devices are in their functional position by actuating or operating elements brought, that is, the switching devices are switched on or off.
  • a mechanical energy store is preferred by switching on a torsion or coil spring tensioned, and the reset of the controls occurs when triggered by a magnetic release or by a thermal trigger by releasing the stored spring energy.
  • the switch position becomes optical displayed to the operator.
  • a spiral spring is used to reset the control element used with the inner bent end on a turned part with a Groove is pushed.
  • the spring is supported on the inner leg by Wedge in the groove and is tensioned by turning the outer leg. After that the outer leg is hooked into a recess provided for this purpose locked.
  • the controls are reset when the actuator is rotating usually a torsion spring is used.
  • the one to be driven by the torsion spring Part is first assembled and the torsion spring is subsequently installed so that the spring body and a spring leg fit into the recesses provided for it.
  • the second leg is assembled by tensioning, positioning and hanging.
  • the object of the invention is to provide a switching device of the type mentioned which makes assembly much easier.
  • the spring designed as a coil spring with its short leg first inserted into the recess, with the short leg in the groove in the axial Direction slides. Then the longer one protruding from the control handle Leg twisted, whereby the spring is tensioned until the longer leg with its offset against a bar comes to rest, causing the spring is held within the handle. Then the one that forms a prefabricated structural unit Handle with spring placed on the key switch until the longer shekel behind clicks into place.
  • FIG. 4 Above the top wall 10, a Housing 11 for a key switch, a rotary handle 12 is shown, which is a circular Has pot section 13 and a handle section 14.
  • a bearing pin 15 which projects vertically is integrally formed on the housing wall 10. Furthermore, a projection 16 in the Area of the rear side edge 18 shown in FIG. 4 on the housing wall 10 molded. This projection has one to the opposite side edge indicative inclined surface 17 and an undercut 19.
  • an opening 20 is made by an actuating pin 21 is penetrated, which is coupled to the key switch (not shown) is that when the actuating pin 21 moves transversely to its longitudinal direction the key switch is switched on or off.
  • the actuating handle 12 is assigned a coil spring 27, which has a screw body 28 has, at one end a tangential leg 29 protrudes, whereas at the other end a shorter leg 30 is bent, which runs in the radial direction and its extension inwards through the center of the screw body or spring body 28 runs.
  • the longer leg 29 has an offset 31.
  • the longer one Leg 38 dimensioned so that it clearly projects radially beyond the flange 24.
  • the actuating handle 12 has an approximately S-shaped recess on its underside trained S-shaped control link 32, which has a radial Section 33 has an approximately U-shaped projection 34 is limited.
  • the link 32 is at the section 33 opposite end 34 of a bar 35 limited, which runs approximately parallel to the radial extension of the groove 26.
  • the Bend 31 on the leg 29 is now selected so that a direct and tangential the screw body 28 connecting section 36 directly quasi straight from the protrudes adjacent turn; a section 37 is formed by cranking, which a distance from the section 36. If now the spring with its spring body 28 is inserted into the recess 25, the short leg 30 in the Groove engages, and then when the longer leg 29 pivots clockwise is, whereby the spring is tensioned, the section 36 slides along the bar 35, until the leg 29 runs parallel to the bar 35.
  • the spring 36 By pushing the The spring 36 enters the recess 36 behind the edge of the last Ledge 35, so that this section is at a distance from the ledge edge, which corresponds approximately to the offset height.
  • the section 36 resiliently lies against the Inside 37 of the bar so that the spring 27 is biased and by its own Spring force remains inside the recess.
  • Switch handle and return spring formed which then placed on the housing wall 10 can be.
  • the bearing pin 15 engages in the recess 25 and thus through the inside of the spring into the control handle; the actuating pin 21 gets into the recess 33.
  • the leg 29 runs on the Inclined surface 17 of the projection 16 and then engages behind the undercut 19, so that the control handle is now fully assembled.
  • Fig. 4 shows part of a motor protection switch; the housing is not shown, the key switch, the contact points and other components, as these for the invention are of little importance.
