Definitions

  • the invention relates to an electrical push button switch mentioned in the preamble of claim 1.
  • Pushbutton switches are switches without latching (locking) of the movable contact pieces, whereby the contact pieces return to their starting position by means of an internal retraction force when the driving force ceases (e.g. finger pressure). Pushbutton switches are preferably used for short-term closing (on button) or opening (off button) of circuits. Pushbutton switches are known as pushbuttons or rocker switches in various embodiments.
  • pushbutton switches which trigger a single switching operation with the aid of snap springs.
  • This principle is preferably used for computer and typewriter keyboards.
  • the snap springs rest with outer contact feet on conductor surfaces. With the help of a fixed plunger, the snap spring is pressed in the middle. If the actuating force acting on the actuating element exceeds the spring return force of the snap spring, it springs over. Since there is a conductor track surface directly in the middle under the snap spring, a connection of the conductor tracks is made after the snap spring. Since the snap spring rests on the circuit board after it has jumped over, further pushing through for the purpose of the stepped connection of a further circuit is not possible. In order to create a step switch, it is necessary that at least a second one is triggered with the same actuating element after a first switching operation.
  • a two-stage button has become known, which is actuated by a linearly displaceable push button and in which two snap springs are arranged one above the other, which are activated in succession by means of a rigid switching plunger acting centrally on the snap springs.
  • the disadvantage here is the small number of switch positions that can be achieved.
  • Another disadvantage is that the step switch requires its own housing, which must be completely attached to a printed circuit board and in which the contact feet led out to the outside must be connected separately.
  • it is disadvantageous that very fine manufacturing tolerances have to be observed in the case of step sensors with two snap springs lying one above the other. The load capacity with regard to switching capacity and service life is also low due to the larger switching travel of the upper snap spring.
  • the step key switch according to the invention can be produced particularly advantageously in a flat design in cooperation with the switching plungers formed on the rocker arms of the actuating rocker in parallel with one another.
  • the preferably dome-shaped snap springs in combination with an alternating gap-setting of the snap springs result in a particularly space-saving arrangement.
  • the snap springs are pre-positioned by means of a positioning plate and placed over a circuit board.
  • the electrical part printed circuit board, positioning plate with snap springs
  • the mechanical part operating rocker with molded switching plungers
  • the step switch according to the invention is equipped on each side of the actuating rocker with a variable-length and a constant-length switching plunger. It can thus be used as a window lifter button for the gradual actuation of window lifter motors in motor vehicles, which results in a 5-position button.
  • a rest position is defined by the horizontal position of the operating rocker.
  • the window is automatically moved to the respective end position with the help of downstream electronics (eg activation of a surge relay). In this case, the button does not need to be pressed any further.
  • the step switch according to the invention has a lower housing part 1, in which a printed circuit board 3 is arranged. On the circuit board 3 there are snap springs SF n , SF n ', which are positioned with the aid of a positioning plate 4 below rocker arms A, A' an actuating rocker 5.
  • the two-armed actuating rocker 5 is mounted so that it can pivot about a pivot axis 16 running parallel to the positioning plate 4.
  • a 'of the rocker 5 are perpendicular to this two two each in the direction of the four spring springs SF1, SF2 SF1', SF2 'pointing switching plunger 8.9.
  • a first actuating rocker bearing (not shown) and at a distance from the pivot axis 16 of the actuating rocker 5
  • there is a second switching plunger 9 and also at the level of a second actuating rocker bearing (not shown) but a first switching plunger 8 is formed at a greater distance from the pivot axis 16.
  • the second switching plunger 9 is designed to be variable in length by means of a slidable and telescopically guided and spring-loaded slider 7 depending on an actuating force acting on the actuating rocker 5.
  • the second switching plunger 9 has a molded-on sleeve 6, in the displacement 10 of which the slide 7 is held by means of molded-on locking lugs 11.
  • the slider 7 is pressurized by a preloaded compression spring DF1, the compression spring DF1 being held biased on the one hand in a first blind hole 13 of the second switching plunger 9 and on the other hand in a second blind hole 14 of the slider 7.
  • the slider 7 can thus be displaced by ⁇ x.
  • the first switching plunger 8 which is always the most distant from the pivot axis 16 switching plunger in embodiments with n switching plungers compared to the second switching plungers 9, is rigid in itself so that it cannot change its length. Its length is always (n-1) ⁇ x shorter than the length of the second switching plunger 9 closest to the swivel axis in a rest position P0.
  • Figure 2 shows a plan view of the arranged in the positioning plate 4 snap springs SF1, SF2, SF1 ', SF2'.
  • Their spherical crown K1, K2, K1 ', K2' are positioned directly below the plunger tips S1, S2, S1 ', S2'.
  • the snap springs SF1, SF2, SF1 ', SF2' are preferably dome-shaped, wherein three rotationally symmetrical around the respective dome apex and parallel to the dome height are performed dome sections.
  • the plunger tips S1, S2 of the switching plunger 8, 9 lie in an alignment plane 15 which forms the maximum tilting angle ⁇ with the positioning plane of the positioning plate 4.
  • the plunger tip S1 of the second switching plunger 9 lies on the crown crown K1 of the associated snap spring SF1.
  • the plunger tip S2 of the first switching plunger 8 has the distance ⁇ x in the rest position P0 from the crown crown K2 of the snap spring SF2 assigned to the first switching plunger 8. Since the spring constant D1 in the second.
  • Switching plunger 9 arranged compression spring DF1 is dimensioned so that it is greater than the spring constant D0 of the snap springs SF n , SF n ', is achieved by the actuating force 5 acting on the operating rocker 5 initially jumps to the second switching plunger 9 associated snap spring SF1. Since there is a conductor track directly in the middle under the snap spring SF 1, a connection of conductor tracks is established via the snap spring SF 1. The tip S2 of the first switching plunger 8 lies on the crown K2. So that a first switching position P1 is reached.
  • the mode of operation of the step switch according to the invention will be described with reference to FIG. 3 in a further exemplary embodiment with three switching plungers 8, 9 formed on each rocker half.
  • the first two switching plungers counted from the pivot axis 16 in the direction of increasing distance are variable-length second switching plungers 9, while the switching plunger most distant from the pivot axis 16 is a rigid first switching plunger 8.
  • the plunger tip S1 rests on the associated snap spring SF1.
  • the plunger tip S2 is removed from the crown crown K2 of the associated snap spring SF2 by ⁇ x.
  • the plunger tip S3 of the first switching plunger 8 is removed from the crown crown K3 of the associated snap spring SF3 by 2 ⁇ x.
  • the compression spring DF2 arranged in the middle second switching plunger 9 has been pushed together by ⁇ x, while the compression spring DF1 located in the second switching plunger 9 near the pivot axis has pushed together by 2 ⁇ x.
  • the plunger tips S1, S2, S3 are all in the positioning plane specified by the positioning plate 4.
