Definitions

  • the invention relates to an electrical installation switch: with a housing with a laterally open cavity for receiving a contact rocker pivotally mounted on a fixed contact part, which is held in its bistable positions by a spring member and which interacts with fixed contact parts mounted in slots in a lower housing wall, with a pushbutton guided in an opening in an upper housing wall, which, under the effect of a return spring, interacts with the rocker to switch the contact rocker by means of a switching plunger, with a lamp arranged in a cavity of the pushbutton with connecting wires which are connected to the fixed contact parts and with one insulating plate closing the cavity of the housing and causing the contact parts to be supported and supporting the pushbutton guide, which is fastened to the housing without further fastening means.
  • An electrical installation switch of this type which has become known from DE-OS 17 65 709, is still of relatively high construction so that it requires a large installation depth for its installation.
  • a large number of individual parts are required here, which require complex assembly.
  • the lamp is connected to the contacts of the switch by a solder connection, so that replacement of this lamp is not possible.
  • the object of the invention is to rock a switch with a contact, the switching of which can be actuated by the pushbutton Switching plunger is designed so that it has a relatively small design, in particular the installation depth st q rk should be reduced. It should be easy to assemble with relatively few individual parts, whereby no complex work processes are required, for example soldering or the like.
  • the push button consists in two parts of a lower plate as a support for the lamp and a surrounding this and attached to the plate by snap connection hood, the plate at its edges at least two approaches are formed with journals for return springs and around the approaches the ends of the connecting wires of the lamp are placed and that the return springs each lie in an open to the push button receptacle of a projecting into the cavity console of the housing side wall and on a connected to a fixed contact part, insertable through a lateral slot in the receptacle and on the bottom of the contact bridge is supported.
  • the contact bridge is clamped as a thin sheet metal lamella with a stationary contact part into the slot of the lower housing wall.
  • journal for the return springs have a slot for receiving the connecting wire of the lamp.
  • a control cam for actuating the switching plunger of the contact rocker is formed on the underside of the plate.
  • the invention is that in the area of the slots for receiving the fixed contact parts in the.
  • Housing wall and openings in the insulating plate are provided for carrying out contact bridges in the case of housings arranged side by side. This makes it a lot side use and design of a switch with different circuits and differently designed lamp arrangements that can be connected to the switch possible.
  • the invention consists in that the plate is formed with lateral guide walls, which are guided with resilient locking lugs in openings in the housing wall and the insulating plate and form a stop in the high position of the pushbutton.
  • This design makes it possible to provide the switch with different pushbuttons or lamp designs, with the possibility that these are interchangeable.
  • the installation switch according to the invention is shown in the drawing in several embodiments.
  • the insulating housing 1 which is uniform for all switch designs, accommodates stationary contact parts 3, 4 or 5 in a lower housing wall 2 in slots, which are held clamped in these slots.
  • the fixed contact part 3 is provided as a bearing contact for a pivotable mounting of a contact rocker 6, this contact rocker 6 being held on the fixed contact part 3 by means of a spring 7 of the housing 1.
  • the contact rocker 6 are rotatably mounted on this switching plunger 9, which are actuated by a push button 1o.
  • the pushbutton 1o is made in two parts and consists of a plate 12 and a hood 13 which overlaps it and which is fastened to the plate 12 by means of latching connections 25.
  • a lamp 14 is optionally arranged with a ballast resistor 15 over the hood 13 is gripped.
  • the plate 12 has projections 17 formed on its edges, around which the connecting lines 16 of the lamp 14 can be placed.
  • journals 18 for the return springs 11 are provided on the underside of the plate. These journals 18 have a slot 19 for receiving the connecting wire 16 of the lamp 14. After the return springs 11 have been plugged onto the journals 18, proper contacting of these return springs 11 with the connecting wires 16 of the lamp is thus ensured.
  • brackets 20 are formed on the housing side walls and have a receptacle 21 which is open to the push button 10 and in which the return springs 11 are properly guided and stored.
  • a lateral slot 23 leads into the receptacle 21 in the region of the bottom of this receptacle 21.
  • a contact bridge 22 can be inserted through this slot 23 and rests on the bottom of the receptacle 21, so that the return spring 1 'can be supported thereon.
  • the contact bridge 22 is connected to the fixed contact part 4 or 5 in such a way that it can be pressed together with the respective fixed contact part 4 or 5 into the slot of the lower housing wall of the housing 1.
  • the plate 12 is formed with lateral guide walls 26 which are guided on the one hand on the bottom wall of the housing 1 and on the other hand on the insulating material plate 24 covering the cavity 8 of the housing 1.
  • This one Guide walls 26 are each formed on resilient locking lugs which lie in openings 28 in the housing wall and the insulating plate 24. The upper free end of the detents comes to a stop at the upper end of the opening 28.
  • these locking lugs 27 are resilient, an easy insertion of the complete push button 10 in the housing 1 through the opening 34 of the upper housing wall is easily possible.
  • the push button 10 can be easily removed from the housing 1 again by external access to the latching lugs 27.
  • the insulating plate 24 is permanently attached to the housing 1 by gluing or thermal deformation.
  • the lamp 14 can be used as a lighting or control device.
  • FIGS. 7 and 8 show an embodiment in which the respective switch position can be indicated by two lamps 14 'in conjunction with a changeover switch.
  • two uniform insulating material housings 1 are provided, which can be arranged next to one another and connected to one another. 6, the switch with its switch contacts and in the other insulating housing 1 according to FIGS. 7 and 9, the lighting device is housed.
  • the two lamps 14 ′ arranged in the pushbutton 10 are connected to the fixed contact part 3 via a common resistor 15.
  • the other connecting lines 16 of the lamps 14 ' are attached to the lugs 17 of the plate 12 in the embodiment according to FIGS. 7 and 8 as in the first example.
  • connecting lines 16 are connected via the return springs 11 to contact bridges 31, which, like 8, in particular, through openings 30 provided in the housing wall and in the insulating material plate 24 in the area of the slots for receiving the fixed contact parts 4 and 5, respectively, to establish a cross connection between the two housing parts.
  • a partition 33 can be provided on the plate 12 or on the hood 13.
  • FIGS. 9 and 10 a simplified lamp design is shown.
  • the other connecting lines 16 are connected directly to contact bridges 35 which, as in the previous example, penetrate the housing wall and the insulating plate 24 in openings 30 and are contacted with the contact parts 4 and 5, respectively.
  • the lamps 14 ' are covered by a hood 36 which is arranged in a fixed manner in the opening 34 of the housing 1 and is held in the openings 28 of the housing wall and the insulating material plate 24 by means of latching lugs 37.
  • a partition 33 is formed on the hood 36.
  • the hood 36 can be made of transparent material.
  • the hood 36 is expediently formed from an opaque material and a window 38 made of transparent material is provided above the lamps 14' in the hood 36.
  • the windows 38 can be of different colors, e.g. red and green, be formed or be provided with symbols.
