Definitions

  • the invention relates to an electrical switch which is to be used in particular for motor vehicles and has the features from the preamble of claim 1.
  • Such a switch is e.g. B. from EP-A-112 483 known.
  • This push button switch has a base with guide walls, on the inside of which grooves are cut out.
  • the grooves have funnel-shaped extensions in the upper area, which are delimited by lugs projecting into the grooves.
  • a swivel slide comparable to the switching plunger is guided by means of stub axles, which is formed from a pressure bracket and two tappets.
  • the above-mentioned lugs projecting into the grooves serve as stops for the stub axles of the pivoting slide.
  • the tappets of the swivel slide alternately engage the assigned parts of the switching linkage of a tilting element which is combined with a contact element to form a contact rocker that can be pivoted about a stationary bearing web.
  • a prestressed spiral compression spring is arranged, which largely immerses in the interior of the swivel slide and must be supported transversely to the swivel plane by lateral wall-like structures of the swivel slide.
  • This spring fulfills three functions at the same time, namely the resetting of the swivel slide and push button after releasing the depressed push button, the stabilization of the switching state of the contact rocker and the swiveling of the swivel slide into the other rest position when the push button is released. A fine adjustment of the spring force to the the force required for the respective function is therefore not possible. A relatively large force must therefore be applied to actuate the pushbutton.
  • the swing valve must have at least two plungers for reasons of space. Additional means must be provided for the spring in relation to the swivel plane of the swivel slide in order to prevent the pretensioned spring from escaping in this direction.
  • the shape of the swivel slide and the engagement of the pushbutton in the swivel slide are correspondingly complicated. Ultimately, this complexity has an adverse effect on simple assembly.
  • corresponding pins are provided for self-clamping reception of the spring ends on the pivoting slide and on the contact rocker.
  • the contact rocker and spring or contact rocker, spring and swivel slide can be preassembled to form a structural unit which is then to be mechanically mountable.
  • this does not avoid the assembly process of these parts, it merely shifts them. It cannot be ruled out that the individual parts are actually captive during mechanical assembly of the preassembled unit, or that the spring will become unusable due to its flexibility due to buckling.
  • This known push button switch has an advantageously simple structure, but long switching strokes of the push button are required to switch to the other stable switching position.
  • malfunctions or switching difficulties can occur if the shape of the spring is not precisely aligned with the apex of the contact pad of the rocker switch due to shape deviations or changes in the shape of the spring or inaccurate assembly.
  • the invention has for its object to develop an electrical switch with the features from the preamble of claim 1 so that a small switching stroke of the push button and a small force on the push button are required for switching to the other switching state that malfunctions in switching operation excluded are and that a simple or mechanical assembly of the switching plunger or the assembly containing the switching plunger is possible.
  • the switching plunger has only one finger which interacts with the rocker switch and, in addition, an attack means for a spring-elastic web of the rocker switch.
  • the rocker switch in turn has between its trunnion next to an open to the switching plunger Recording for the finger of the switching plunger, which is equipped with stops in the pivoting direction for the finger of the switching plunger, a spring-elastic web protruding in one piece from it.
  • This web which acts as a spring, engages - as seen from the pivot axis of the rocker switch - beyond the pivot plane of the switching plunger on the attack means.
  • the spring-elastic web of the rocker switch swivels the switching plunger and thus its finger into the other rest position with each switching operation.
  • a switch of this type requires only a small stroke of the pushbutton for switching to the other switching state, since the changeover of the switching plunger to the other rest position is not derived from the lifting movement of the pushbutton.
  • the required pressure force on the push button can also be kept low, since the spring force of the various springs can be sensitively adjusted to the lowest spring force required for the respective function.
  • the engaging means located on the switching plunger for the resilient web is a shaft into which the resilient web engages and in which it is guided at the same time.
  • the displaceability and the pivotability of the switching plunger are obtained in a simple manner in that, according to claim 3, the plunger is mounted with the aid of at least one pivot pin and at least one elongated hole. Is according to claim 4, the slot in the base plate and the pivot pin on the switching plunger, the pivot axis is fixed with respect to the switching plunger.
  • the plunger is advantageously held captively on the base plate. This greatly simplifies the assembly and functional testing.
  • This captivity of the plunger is achieved with simple assembly according to claim 5 in that the elongated hole has an insertion slot, preferably provided with an insertion bevel, the width of which is smaller than the diameter of the pivot pin.
  • the housing 10 of the electrical switch shown is composed of a frame 11 and a base plate 12.
  • the base plate 12 is provided with a series of raised parts that perform storage and support functions.
  • a rocker switch 13 is pivotally mounted in it by means of two pivot pins 14. With these pivots 14, the rocker switch 13 is inserted into two grooves 15 so far that the pivots 14 have each skipped a locking projection 16 at the bottom of the grooves and are thus secured in the grooves 15.
  • a leaf spring is clamped as a snap spring 20 with one end in the rocker switch 13, while it is supported with its other end in a notch in a metal sheet 21.
  • the distance between the bearing axis of the rocker switch 13 and the metal sheet 21 and the length of the leaf spring 20 are coordinated so that the leaf spring must be bent and the rocker switch 13 holds after switching over in the end position reached.
  • a movable contact tongue 22 is formed in one piece with a contact bead 23 which interacts alternately with two fixed contacts 24 and 25 held on the base plate 12.
  • each groove 15 there is above each groove 15 an elongated hole 32, the longitudinal direction of which corresponds to the longitudinal direction of the grooves 15 and which is at the top in one with a Insertion bevel 33 provided insertion slot 34 opens outwards.
  • the width of the insertion slot 34 is smaller than the width of the respective elongated hole 32.
  • the elongated holes 32 penetrate the columns 30 and 31 over their entire width, so that the two columns in the area of the elongated holes 32 have a clothespin-like shape.
  • the two elongated holes 32 are each closed to the outside towards the frame 11 by a metal sheet 35 which is inserted in the base plate 12, penetrates it and forms a flat plug on the outside.
  • a switching plunger 40 engages with two pins 41, the diameter of which corresponds to the width of the elongated holes 32, and is thus mounted such that it can be moved in the longitudinal direction of the elongated holes 32, but at the same time can also be pivoted.
  • the switching plunger 40 When the switching plunger 40 is pivoted, its pivot axis is formed by the axis of the pins 41, so that it is fixed relative to the switching plunger 40.
  • the pins 41 are pressed into the elongated holes 32 through the insertion slots 34.
  • the insertion slots 34 widen in the process.
  • the pin 41 and thus the switching plunger 40 are secured in the elongated holes 32 and thus on the base plate 12, since the width of the insertion slots 34 is smaller than the diameter of the pin 41.
  • the distance between the end faces 42 of the two pins corresponds approximately to the distance the mutually facing side surfaces of the metal sheets 35, so that the switching plunger 40 has little play in the direction of the axis of the pin 41.
  • a bore 45 opens into each slot 32, into which a helical compression spring 46 is inserted.
  • a mandrel 47 runs inside each helical compression spring 46 and lies with a plate 48 between the helical compression spring and the pin 41.
  • the helical compression springs 46 press the pins 41 against the upper end of the elongated holes 32.
  • the mandrels 47 are spaced from the bottom of the bores 45 so that they move the switching plunger 40 downward do not hinder.
  • One pivot pin 41 of the switching plunger 40 extends from the elongated hole 32 far inward, where a finger 49 is formed on it, which projects into a receptacle 50 of the rocker switch 13 which is open towards the switching plunger 40 and which has two stops in the pivoting direction of the switching plunger 40 51 provided and the bottom 52 is slightly shaped like a gable roof.
  • the rocker switch 13 has a resilient web 60 which extends beyond the axis of the pivot pins 41 of the switch plunger 40 and which, viewed from the pivot axis of the rocker switch 13, extends beyond a shaft 61 beyond the axis of the pivot pins 41 on the switch plunger 40 attacks.
  • the web 60 pivots the switching plunger 40 in such a way that in an end position of the switching rocker 13 it rests against a stop 51 of the receptacle 50 of the switching rocker 13.
  • a push button 65 is guided in a straight line displaceable within a limited distance. Return springs, not shown in the figures, ensure that the pushbutton returns to the position shown in the figures after actuation.
  • a pin 66 is molded onto the pushbutton, which extends through an intermediate ceiling 67 of the frame 11 in the rest position of the pushbutton 65 and the switching plunger 40 to just before these. It can act on the switching plunger 40 on the outer circumference of the pivot pin 41, which extends far inwards, exactly above the finger 49.
  • the switching plunger 40 is carried along via the pin 66. Its finger 49 remains on the stop 51 of the receptacle 50 of the rocker switch 13 and pivots the latter - viewed in FIG. 1 - clockwise.
  • the snap spring 20 curves S-shaped until its dead center is overcome, and then suddenly switches the rocker switch 13 to the other end position. If the push button 65 is then released, the switching plunger 40 returns with its pivot pin 41 to the upper end of the elongated holes 32 back and is thereby pivoted clockwise by the web 60 of the rocker switch 13 until it rests on the other stop 51 of the receptacle 50 of the rocker switch 13.
