Definitions

  • the invention relates to an electrical push button switch mentioned in the preamble of claim 1.
  • Pushbutton switches are generally constructed as bistable switches. Here, the linear movement of a push button is converted into a tilting movement acting on the electrical switching element with the aid of a switching mechanism. Each time the push button is pressed again, the switching element assumes the other of the two possible switching positions.
  • a push button acts on a pressure bracket, which engages in depressions with its tappets formed on both sides in corresponding formations in a tilting element which by engaging in the each other tilt position is pushed. Because the tilting element is again in operative connection with a contact element, its change in position leads to an electrical switchover.
  • a coil spring which can be subjected to pressure and is inserted between the pressure bracket and the tilting element is used.
  • the object of the invention is to provide a pushbutton switch that manages with as few parts as possible, these parts should at the same time be designed so that automatic assembly is possible.
  • This object is achieved by the features characterized in claim 1.
  • Advantageous refinements and developments of the invention are characterized in the subclaims net.
  • the contact rocker which can be pivoted on a fixed bearing web, can be inserted very easily into the base of the switch.
  • the same also applies to the pressure bracket, which acts as a swivel slide, since it is equipped with bearing journals that can slide up and down in grooves or elongated holes. The guidance guaranteed by the grooves makes it easier to fit the swivel slide into the base and at the same time ensures defined positioning.
  • the compression spring can be easily attached.
  • the self-clamping fastening of the compression spring on the pivot of the swivel slide also enables these two parts to be pre-assembled.
  • the compression spring can also be attached to the pin of the contact rocker in a self-clamping manner, as a result of which the pivoting slide, compression spring and contact rocker can then be mounted as a structural unit in the base.
  • the push-button switch Since the push-button switch must fit in standard flush-mounted boxes, it is advantageous if it has only a small overall height.
  • a feature that contributes decisively to this is the arrangement of the stub axles on the swivel slide, which is such that the axis of rotation of the swivel slide lies between the two ends of the compression spring. Because of this and also because of the low mutual spacing of the plunger of the swivel slide engaging in the switching link allows a defined switching to be achieved with a very small switching stroke, which can be less than 3 mm
  • the compression spring is surrounded on both sides by the same symmetrically opposing parts of the swivel slide and the pressure wedges formed on the push button. This also results in a symmetrical distribution of the compressive forces and prevents unwanted tilting of the parts in contact with the compression spring.
  • the grooves recessed on the inside of the guide walls arranged in the base are widened like a funnel in the area of the base opening. This makes it easier to insert the swivel slide into the base. However, the funnel-like area is separated from the action area in which the stub axles of the pivoting slide can slide. These lugs also act as stops and thus determine the rest position of the pivoting slide.
  • the pivoting angle of the pivoting slide is determined by an appropriate design of the side walls forming the pivoting space, which serve as a stop.
  • the push button switch can also be designed as a multiple switch with two or more contact rockers and two or more swivel slides. By appropriate training of push button and swivel slide several switching units can be switched together or separately. Good parallel guidance must also be ensured for the pushbuttons.
  • the base is provided with an approach that the push button detects all around in the sliding fit.
  • the base has guide holes into which guide pins formed on the pushbutton are inserted.
  • the push button switch has a base 10 in which A contact rocker 2 is pivotally mounted on a bearing web 1 of a fixed contact part.
  • a switching link 3 is formed on the contact rocker 2, which has corresponding recesses into which the plungers 5 of a swivel slide 4 can engage.
  • the pivoting slide 4 is also provided with stub axles 8, which can slide in grooves 9, which in turn are formed in guide walls 21.
  • Pressure wedges 13 are formed on a pushbutton 11 and engage with their ' tips in wedge-shaped recesses 14 of the swivel slide ' 4.
  • the bistable switching behavior of the pressure switch is determined not least by a spiral compression spring 6.
  • This compression spring 6 is attached with its two ends to pins 7, 20, the pin 7 being formed centrally within the swivel slide 4 and the pin 20 in the middle of the switching link 3. Via the swivel slide 4 and the pressure wedges 13, the compression spring 6 acts on the pushbutton 11 and ensures that it returns to its starting position after actuation.
  • the swivel slide 4 which is guided in its grooves 9 by its stub axle 8, follows all rectilinear movements emanating from the pushbutton 11. At the same time, the stub axles 8 also allow a pivoting movement of the pivoting slide 4, the possible pivoting angle being limited by the side walls 22 delimiting the pivoting space.
  • the plungers 5 of the swivel slide 4 assume such a position on one side that they are located above a recess in the switching link 3.
  • the plunger 5 engages in the switching link 3 so that it is pressed downwards on one side.
  • the contact rocker 2 tilts into the other switching position.
  • the compression spring 6, which is now pressed in the other direction by the switching link 3, passes this pressure on to the pivoting slide 4, so that this is also brought into the other rest position when the push button 11 is released.
  • the exemplary embodiment shown is a bistable switch.
  • the push-button switch is installed in such a way that the fixed contact parts are first introduced into the base 10. Then the contact rocker 2 is placed on the bearing web 1. The pivoting slide 4 is now pressed into the base 10 via funnel-like bevels of the grooves 9. Here, the stub axles 8 of the swivel slide 4 slide over the elastic lugs 23 into the grooves 9. The lugs 23 prevent the swivel slide 4 from sliding back.
  • the compression spring 6 fastened at one end to the pin 7 of the swivel slide 4 hits its other end the pin 20 of the contact rocker 2. Finally, the push button 11 can be plugged in, not shown locking elements falling out of the push button prevent.
  • the entire internal switching mechanism thus lies below the level of the support ring 12 lying on the wall.
  • the support ring can be made completely flat and attached to the base 10 by means of rivets, screws or locking members.
