Definitions

  • the invention is based on a push button switch according to the preamble of claim 1, as is known from DE-C-1 910 165.
  • Another switch is known from BE-A-508 615.
  • This consists of a housing, in the housing wall of which a slide switch is slidably mounted.
  • a compression spring is arranged in a hollow central part of the slide switch, which is supported at one end on the bottom of the hollow central part and at the other end on the contact element itself.
  • This contact element is pivotally mounted at one end in a notch in the housing wall.
  • the compression spring serves both as a spring mechanism and for generating the contact pressure. Furthermore, the compression spring presses the slide switch against the housing wall.
  • a key slide is arranged displaceably against the force of a return spring, through which a contact bridge arranged on a jump piece can be moved relative to fixed contact pieces.
  • a button is also formed on the key slide.
  • the movable jumping piece Connected to the key slide via a compression spring is the movable jumping piece, which has locking arms formed on both sides with locking lugs, which interact with locking grooves in the housing, and which can slide on the stepped end of the key slide.
  • the switch housing itself is closed by a lid.
  • a slide button which has a heart-shaped backdrop, in which a Z-shaped locking member is guided, is displaceable in the housing against the force of a return spring.
  • This locking member can consist of wire or have the shape of a pin.
  • One end of the locking member plunges into the heart-shaped backdrop, while the other end is fastened in the housing cover.
  • a leaf spring presses the associated end of the locking element into the setting.
  • the leaf spring is punched out of a metal band and has a notch on both sides.
  • a cut-out tongue is bent out at an angle of 45 degrees. The relatively long arm presses on the locking element.
  • a switch in whose housing a slide switch made of plastic can be moved.
  • Fixed counter contacts and connecting pieces are arranged in the housing.
  • contact elements which are pivotally mounted about the fixed connecting pieces and which can be jumped by operation of the slide switch.
  • the contact elements are designed as two-armed levers, the first arms interacting with the mating contacts, while the second arms engage in notches in the slide switch.
  • There is also a compression spring which serves as a spring mechanism and which is used to generate the contact pressure.
  • the compression spring forms the counter bearing to the first bearing, which is formed by the second arms engaging in the notches.
  • the compression spring is supported with one end at the bottom of a cavity of a pot-shaped middle part of the slide switch and with its other end in a recess in the opposite housing wall.
  • the object of the present invention is to provide a pushbutton switch according to the type mentioned in the first part of claims 1 so that, with a reduced number of individual parts, it has a space-saving, compact structure and is simple and inexpensive to produce. Furthermore, the push button switch should be suitable for simple assembly in printed circuits.
  • the push-button switch shown in FIG. 1 has an approximately cuboid housing 1 made of plastic with housing walls 3 and a housing base 2.
  • the stationary counter contacts 5 provided with solder connections protrude through slots in the upper housing wall.
  • the counter contacts can also be injected into the housing wall.
  • Approximately in the middle of the housing 1 are stationary in adapted grooves, also with external solder connections provided connectors 6 attached to which the contact elements 7 are pivotally mounted. With their shoulder surfaces, they lie in dovetail-shaped recesses in the connecting pieces 6.
  • the contact elements 7 are designed with two arms, the first arm 8 (in FIG. 1 the left arm) flying against the counter contacts 5 in the switched-on state shown.
  • the first arms 8 can be provided with precious metal contacts at the locations of the support.
  • the second arms 9 (the right arm in FIG. 1) of the pivotable contact elements engage in U-shaped or V-shaped notches 10 of a slide switch 4.
  • the slide switch 4 has as a projection a pot-like central part 14 in the form of a hollow truncated cone.
  • a helical compression spring 11 is supported with one end.
  • the contact elements 7 engaging in the notches 10 perform a pivoting movement in their bearing points on the connecting pieces, by means of which the contact rivets 26 are lifted off the counter contacts.
  • the slide switch 4 experiences a displacement on a circular arc, the radius of which corresponds to the length of the arm 9.
  • the front end of the helical compression spring 11 is carried along from the pot bottom of the middle part 14.
  • a plastic sliding tab 15 shown in FIG. 2 which has a molded actuating button 18 on its front end protruding from the housing.
  • the slide button is guided in the housing by means of two plain bearings.
  • the one slide bearing is formed in that the actuating button 18 is guided on a hollow extension 19 of the housing end wall in such a way that this extension protrudes into a recess 20 in the actuating button.
  • the projection 19 is hollow on the inside, so that the helical compression spring 11 passes through the opening 19 through an opening in the housing end wall and is supported with its second end on the bottom of the recess in the actuating button.
  • the spring 11 also serves as a return spring for the slide button.
  • the cover 24, which closes the housing, is molded onto the sliding key 15, which is expediently so large that the housing is closed in both locking positions.
  • housing partition piece 23 which extends partially into the interior of the housing so that it is located between the mating contacts 5.
  • the housing partition piece also partially protrudes from the housing wall. This housing partition is divided into two halves by an incision 22.
  • a latching tongue 21 is formed, which is arranged perpendicular to the sliding direction. With the help of this locking tongue 21, the sliding button 15 is now snapped into the incision 22. Since the incision is elongated, the locking tongue can slide along it. This connection thus represents the second slide bearing of the key slide.
  • the push button switch has two locking positions.
  • a so-called heart-shaped link 17 is recessed in the sliding button 15, in the guide groove of which a locking member 16 is guided.
  • the mode of operation is generally known, so that it is not discussed in more detail here.
  • the locking member itself is mounted transversely to the sliding direction of the sliding button in the housing partition. Its molded pin engages the backdrop. Laterally, the locking member has a molded pin 25 which protrudes from the housing wall 3 and which triggers z. B. allowed by a magnet.
  • a recess 27 is also provided in the sliding key, into which a pin 28 engages, which is integrally formed on the switching slide 4 and which causes the coupling between the sliding switch and the sliding key to be carried along.
  • the push button switch can be connected directly to the chassis using e.g. B. a screw.
  • the housing end wall 12 has a downwardly extending extension 29 which has an opening 30 in the center for receiving the screw.
  • the push button switch can also be inserted into a printed circuit 31, 32 or 33.
  • Three variants are shown one below the other in FIG.
  • the printed circuit 31 has an elongated recess 34 in two Corners inwardly directed projections 35.
  • the assembly is now carried out such that the push button switch is first inserted vertically from above into the recess and into the slots 36. Then the push button switch is moved slightly parallel to the printed circuit until it stops. As a result, the projections 35 pass between two cutouts 37 of the extension, so that detachment is prevented in this position.
  • the extension 29 of the housing end wall has a longitudinal slot 39 in the middle and lugs 40 projecting on both sides at the height of the opening 30, which lugs can be compressed when inserted into the elongated recess 41 of the printed circuit 33 and spring open again after insertion .
  • the recess is somewhat wider than the width of the extension 29, but not so wide that the push button switch can fall out again after insertion.
