Definitions

  • the invention relates to an electrical pushbutton 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 by a at the free ends of the switching plunger with a shifting gate, acting under the action of a return force push button is switchable.
  • the object of the invention is to improve an electrical pushbutton switch.
  • 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 coupling attachments of the drivers engage in a claw-like manner in such a way that each coupling attachment lies to the side of the axis of symmetry formed by the pivot bearing of the contact rocker, an extension of the coupling attachment overlapping a step of the coupling attachment of the adjacent driver.
  • the overlap of the extension and step has an air gap.
  • the invention is designed in such a way that the coupling attachment is provided with a receptacle for holding the self-resilient switching plunger.
  • 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 attached to each of these contact rockers 4, 4' for coupling a plurality of contact rockers 4, 4 'lying next to one another.
  • this driver 8 is held in a form-fitting manner by means of locking projections 9 within openings 10 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 is designed with three fingers, is inserted with its fingers.
  • the middle finger of the switch plunger is at its free end bent out of the plane of the switching plunger 16 in a roof-shaped manner and passes through an opening in the pocket, where it comes to rest behind an edge of the opening and presses 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 form a pivot bearing when the switching plunger 16 is actuated by the pushbutton 6 With two contact rockers 4, 4 'only a few switching plungers 16 are required.
  • 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. For example, it can be pot-shaped, the fixed contact parts 2 and 3 and the contact rockers 4 each being able to be inserted into the top of the housing 1 from above.
  • the housing 1 is designed such that it is open at 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 the lower wall of which is the fixed 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.

Claims (5)

1. Commutateur électrique à bouton-poussoir, avec une bascule de contact (4) montée à pivotement sur une pièce de contact fixe (2) et maintenue à ses positions bistables par un organe élastique (5), cette bascule de contact pouvant, au moyen de poussoirs de commutation déformables élastiquement (16), montés sur elle avec possibilité de pivotement, en étant espacés symétriquement du palier de basculement et formant saillie à peu près perpendiculeairement sur elle, être manoeuvrée par un bouton-poussoir (6) qui attaque les extrémités libres des poussoirs de commutation (16) par une coulisse de commande et qui est soumis à l'action d'une force de rappel, caractérisé par le fait que, pour coupler la bascule de contact (4) à au moins une autre bascule de contact (4'), chacune d'elles (4, 4') est liée, par conjugaison de formes, à un entraîneur (8, 8') en matière isolante, pour réaliser un entraînement forcé de l'entraîneur voisin (8, 8')
2. Commutateur électrique à bouton-poussoir selon revendication 1, caractérisé par le fait que l'entraîneur (8, 8') est fixé à la bascule de contact (4,4') au moyen de saillants de verrouillage (9,9').
3. Commutateur électrique à bouton-poussoir selon revendication 1 ou 2, caractérisé par le fait que des saillants d'acouplement (11, 11') des entraîneurs (8, 8') viennent mutuellement en prise, à la manière de griffes, de façon que chaque saillant d'accouplement (11, 11') soit situé latéralement par rapport à l'axe de symétrie (14) formé par le palier de basculement de la bascule de contact (4, 4'), un prolongement (12, 12') du saillant d'accouplement (11, 11') chevauchant un épaulement (13, 13') du saillant d'accouplement (11, 11') de l'entraîneur voisin (8, 8').
