Definitions

  • the invention relates to a rocker switch with the Features of the preamble of claim 1.
  • rocker switch is known from US-A-4 203 017. This slides when the rocker switch is actuated the tip part of the switching element along the contact arm while tensioning the spring. A swiveling movement of the rocker switch is in this introductory switching movement prevents the rocker switch from touching the other contact arm acts and holds the rocker switch with it until after If the dead center is exceeded, the rocker switch overtakes the other Releases contact arm and the biased switching element contact arm acted upon by the tip part under spring force flipped and contacted.
  • the invention is therefore based on the object, a generic Train rocker switches in such a way that with simple Build a reliable, volatile shift when switching on and off is guaranteed and the snap behavior the rocker switch both when switching on and off excludes downshifting or contact bouncing.
  • the task is solved by the in the labeling part of claim 1 specified features.
  • the switching element Defined dead center positions created over the hump the switching process abruptly after they are exceeded is accomplished.
  • the arrangement is advantageously made such that the opening of the contacts and the jump of the contact rocker in the zero position is carried out essentially simultaneously. On this way it is achieved that the rocker switch from its stable switch-on position surely leaps over your unstable Dead center position snaps into the stable switch-off position.
  • the 3-position rocker switch shown in the drawing has a T-shaped rocker 10 which is fixed to the housing Rocker axis 12 is pivotable to both sides.
  • the horizontal leg 14 of the rocker is used for switching operation.
  • the vertical leg 16 is hollow and slidably guides a sleeve 18 with a closed tip part 46, the by a compression coil spring 20 against a side symmetrical trained contact rocker 22 is biased.
  • the middle section the contact rocker 22 has protruding laterally Bearing plate 36, which is supported on bearing blocks 42 are.
  • the metallic pillow blocks 42 which over the bearing plate 36 with the contact rocker 22 constantly in contact stand, are with an access terminal, not shown electrically connected.
  • the bearing blocks 42 are from Middle leg 40 U-shaped supports 24 in front, the side legs inside stop surfaces 48 for the bearing plate 36 form.
  • the one-piece contact rocker 22 has two V-shaped angled from the central section with a wide apex angle extending contact arms 26, the switching contacts 28 wear, which cooperate with one of the outgoing terminals 30.
  • the contact rocker 22 points downward in the middle section directional embossing and adjacent to it two upwards Embossments 34, which form projections or bumps and cooperate with the tip part 46 of the sleeve 18. How 2 can be seen in the zero position of the switch the conical tip portion 46 of the sleeve 18 in the Expressions 32 pressed in by the spring 20, whereby the Center position of the contact rocker 22 is centered.
  • the bearing plates attached to both sides of the contact rocker 36 are provided with bevels 38 at their ends, which run diagonally downwards and inwards.
  • the bearing blocks 42 are with the middle leg 40 directed bevels 44 on which the bearing plate 36 hit during the tilting movement of the contact rocker 22.
  • FIG. 5 to 8 illustrate the opening process of the Switch.
  • the Tip part first on the contact arm 26 until it on the Hump 34 abuts.
  • a bearing clearance ⁇ x between the position Bevel 38 of the inclined bearing plate 36 and inner stop surface 48 of the side leg of the support 24.
  • the inclined bearing plate 36 rest on the bevel 44 of the bearing blocks 42.
  • the bevels 38 are chosen so that they are in the switch position at the beginning of the opening movement essentially run parallel to the stop surface 38.
  • the measure ⁇ x forms the bearing clearance, i.e.
  • the tip portion 46 of the sleeve 18 may bump 34 and use it to move the bearing plates 36 to the left, until the bevel 38 on the stop surface 48 is present, i.e. until the bearing clearance ⁇ x becomes zero.
  • This stop position can be seen from Fig. 6. In this position 6, the pressure point of the sleeve 18 is between Bearing point and contact point, i.e. the contact is still closed. The resulting stiction between bevel 38 and the stop surface 48 keeps the contact closed.
  • the jumping behavior of the contact rocker 22 is determined by the above hump 34 determined. Since the tip part 46 the sleeve 18 cooperates with the upwardly directed bumps 34, the downward embossing 32 can be omitted and be replaced by a straight connection.
