Definitions

  • the invention relates to a motor vehicle ignition or glow starter switch according to the preamble of claim 1.
  • Such a known motor vehicle ignition switch (DE-AS 25 55 110) has at its base part a central center contact and several edge contacts, while the driver or the switching wheel holds a bridging element which is constantly conductive with a contact head of a double contact aligned with the switch axis under bias is connected to the center contact and its current-carrying contact finger sweeps over the edge contacts.
  • the driver or the switching wheel also holds a switching bridge, the switching arm of which rests on a switching profile, the central center contact of which can thus be lifted off from the other contact head of the double contact, and the contact legs of which also slide in a current-carrying manner over the respective edge contacts.
  • the known motor vehicle ignition switch is based on known switches (DE-GM 6 801 832 and DE-GM 73 10 447) with a single lifting switching bridge.
  • a further switching bridge was arranged in a doubling of the known switching principle on the driver or ratchet wheel, with a bridge between the center contact and the one contact head of the Double contact is located and slides with a switching arm on a further switching profile, a contact coating of this further switching bridge cooperating as a lifting contact with a mating contact on the base part.
  • the current is supplied via the central center contact, and all the contacts serving to supply the current are therefore necessarily aligned centrally with the center axis of the switch.
  • each switch contact head must have a sufficiently long switching path to ensure correct contacting and interruption in order to avoid premature or completely unintentional contacting.
  • difficulties arise in the control of the contact arms due to the curved or cam tracks arranged concentrically to the switch axis of rotation on the switch housing, the curve profile of which only allows a certain amount of incline between the individual rest points of the switch, which is due to large switching distances can easily be exceeded in an impermissible manner.
  • Such a known switch must also have a relatively large axial length, which in turn has a disadvantageous effect on the formation of the locking curves between the driver or ratchet and the switch housing, in which locking pins loaded by spring pressure usually slide along the driver.
  • cam tracks or cam tracks for the control of the contact arms on the circumference of the base part or the switch housing can only have a certain limited length, difficulties also arise when a larger number of consumers are to be connected in succession at smaller angular intervals.
  • the invention has for its object to provide a motor vehicle ignition or Glühanlrawschalter according to the preamble of claim 1 so that despite a reduction in the axial length of the switch, a larger number of switching positions can be realized at smaller angular intervals than before, without this the functional reliability and reliability of the switch is adversely affected.
  • contact arms are cranked in a U-shaped manner in the area of the switch axis of rotation and arranged in a common plane in a cross manner, and in that the contact heads are assigned at least one contact ring arranged concentrically to the switch axis of rotation as a counter contact .
  • the inventive design of the switch with cranked contact arms arranged crosswise in a common plane with contact heads arranged outside the axis of rotation of the switch and with at least one contact ring arranged concentrically to the axis of rotation of the switch results in the advantage of a more versatile switch design.
  • Several contact arms can be switched simultaneously or independently on the contact ring. Since the contact arms have no center contact, they can be arranged closer together along the switch axis of rotation without the risk of incorrect switching.
  • the contact arms can also have a greater radial length than in the known switch construction, which results in a greater circumferential length of the cam or cam tracks on the switch housing, which in turn enables a more frequent switching sequence in a large number of smaller angular distances between the individual circuits.
  • a high cogging torque can be achieved in that at least two locking curves are arranged on the base part or cover part of the switch housing, each of which is assigned at least one spring-loaded bolt on the driver or ratchet wheel.
  • the arrangement of locking curves and locking bolts can also be made so that the locking curves on the driver or ratchet and the spring-loaded locking bolts on the base part or cover part of the switch housing are arranged accordingly.
  • the switch shown is an ignition or glow starter switch for motor vehicles. Such switches are required for the independent switching of several consumers.
  • the switch consists of a base part 1 with radially outwardly directed fastening eyes 2, which is formed on its upper side by a cover part 3 with a central rotary bearing 4 for a driver or a switching wheel 5.
  • connection terminals 6, 7, 8 project downward from the base part 1, one (6) of which is connected to a contact ring 10 arranged concentrically to the switch axis of rotation 9, while the other connection terminals 7, 8 and further terminals (not shown) lead to corresponding consumer contacts 11, 12 , 13, 14, 15 belong, which are arranged on the top of the base part 1 around the contact ring @ distributed (Fig. 2).
  • the driver or the switching wheel 5 has an upper engagement opening 16 for a lock cylinder or the like and can be rotated in the switch housing against the action of a helical torsion spring 17.
  • each of the two locking pins 18, 19 is under the pressure of a coil spring, not shown in the drawing.
  • each of the two contact arms 22 23 has a contact head 22c, 23c, which is switched when the switch is actuated in accordance with the course of the external cam tracks 22 ', 23'.
  • the contact head 22c, 23c is offset radially outwards on each contact arm 22, 23 with respect to the switch axis of rotation 9.
  • Both contact arms 22, 23 are arranged crosswise (FIGS. 3 to 5), and each contact arm is assigned a holding contact 26, 27, which work on the same level with the working and consumer contacts 11, 12, 13, 14, 15, however, by means of additional cam tracks 28, of which only one cam track is shown in FIG. 2, can be lifted off the contact ring 10.
  • the additional cam tracks 28 for the holding contacts 26, 27 are also arranged concentrically around the switch axis of rotation 9, but radially within the consumer contacts 11 to 15.
  • the contact ring 10 and the contact heads 22c, 23c are expediently silver-plated, but can be coated with another suitable contact material if this is only designed so that it suffices the high stresses to which it is subjected in motor vehicle ignition and glow starter switches withstands.
  • the holding contacts 26, 27 are either spring-loaded or consist of a resilient material and can either run on the contact material 10a of the contact ring 10 or radially next to it, which is generally preferred in order to avoid undesirable damage to the contact material by the holding contacts sliding over it.
  • the two curves can also be located on the base or base part 1.
  • two separate contact rings or an additional contact bridge can also be provided for the two contact arms 22, 23.
