Definitions

  • the invention relates to an electrical installation - switch with a contact rocker, which is pivotally mounted on a fixed contact part and is held in its bistable positions by a spring member and which is pivotally mounted on it from the pivot bearing at a symmetrical distance, approximately vertically projecting, self-resilient switching plunger can be switched over by a pushbutton which acts on the free ends of the switching plunger with a switching link and is under the action of a return force.
  • the object of the invention is. to improve a push button switch in the manner described at the outset for the use of two or more contact rockers which are to be switched by a common push button, that a reliable forcible common switching of the contact rockers can be guaranteed with few means.
  • the contact rockers should be so independent of each other that they do not interfere with each other in the respective contact.
  • this is achieved in that for the coupling of the contact rocker with at least one further contact rocker per contact rocker, a driver made of insulating material is provided in a form-fitting manner, to which a coupling attachment is molded to forcefully take the neighboring driver.
  • the driver is attached to the contact rocker by means of latching projections.
  • the invention is further characterized in that the coupling approaches of the drivers engage in a claw-like manner, such that each coupling approach lies to the side of the axis of symmetry formed by the pivot bearing of the contact rocker, an extension of the coupling approach engaging over a step of the coupling approach of the adjacent driver.
  • the overlap of the extension and step has an air gap.
  • the invention also consists in the coupling attachment being provided with a receptacle for holding the self-resilient switching plunger.
  • the installation switch according to the invention is shown in the drawing using an exemplary embodiment.
  • the stationary contact part 2 serves as a pivot bearing for a contact rocker 4 held on it by means of a spring 5.
  • the contact rocker 4 is switched by means of a pushbutton 6, which is guided in the housing 1 in a longitudinally displaceable manner, via switching plungers 16 into their bistable positions.
  • the push button 6 can be returned to its starting position by means of return springs 7 mounted in the housing 1.
  • a driver 8, 8' is fastened to each of these contact rockers 4, 4 '.
  • this driver 8 is by means of locking lugs 9 within Openings 10 are held in a form-fitting manner on the contact rockers 4.
  • the driver 8, 8 ' is formed with a coupling projection 11 or 11' pointing in the direction of the adjacent contact rocker 4 or 4 '.
  • the coupling lugs 11, 11 'of the adjacent drivers 8, 8' engage in a claw-like manner.
  • Each coupling lug 11, 11 ' is located laterally on the axis of symmetry 14 formed by the pivot bearing of the contact rocker 4 or 4'.
  • each coupling lug 11 or 11 ' has an extension 12 or 12' which the opposite coupling lug 11 or 11 'overlaps at a step 13, 13'.
  • the overlap of extension 12 or 12 'and step 13 or 13' has an air gap 17.
  • Each coupling extension 11, 11 ' is also provided with a receptacle 15 or 15' for holding a self-resilient shift plunger 16, respectively.
  • This receptacle 15, 15 ' consists of a pocket open towards the pushbutton 6, into which the switching plunger 16, which has three fingers, is inserted with its fingers.
  • the middle finger of the switching plunger is bent out roof-shaped at its free end from the plane of the switching plunger 16 and passes through an opening in the pocket, coming to rest behind an edge of the opening and pressing the outer fingers against a side wall of the pocket.
  • the front end edges of the outer fingers rest on the bottom of the pocket and here form a pivot bearing when the switching plunger 16 is actuated by the pushbutton 6.
  • the fact that the switching plungers 16 are used in the coupling lugs 11 and 11 'is for the switching system with two contact rockers 4, 4 'only a few switching plungers. 16 needed.
  • the assembly of the contact rockers 4, 4 'with the attached carriers 8, 8' with switching plunger 16 in the housing 1 is also extremely simple.
  • the housing 1 can basically have a different configuration. E.g. it can be pot-shaped, the stationary contact parts 2 and 3 and the contact rockers 4 can each be inserted from above into the pot of the housing 1.
  • the housing 1 is designed such that it is open on the side and to a certain extent represents a frame, in the upper wall of which the push button 6 can be inserted into an opening and in the lower wall of the stationary contact parts 2 and 3 from both sides in niches can be stored.
  • the contact rockers 4 and 4 'with the carriers 8, 8' attached to them and the switching plungers 16 inserted into them are inserted into the housing from the open sides.
  • drivers 8 can be provided on the middle contact rockers 4 with two coupling projections 11, which, however, are formed diagonally offset opposite one another on the driver 8, so that they engage in a claw-like manner in the example shown.
