Definitions

  • the invention relates to a coding switch on a flat substrate circularly arranged contact points and with a rotatable, interacting with the fixed contact points Switching element that is constantly engaged with a stands on the substrate arranged lead contact point.
  • a coding switch of the type mentioned above is by the EP 0 050 804 A2 has become known.
  • the fixed contact points are with this coding switch on several concentric Circular paths arranged, the rotatable switching element Provide sliding contact for each of the circular paths is. Proceeding from this, the object of the invention is the number of contact points for a given number of switching positions to be coded as low as possible make and thus simplify the coding switch and more reliable to design.
  • a uniform construction principle is essential for the invention for coding switches with different numbers to be coded Switch positions. It is always the number of lines to be queried half the number of Switch positions, plus one connecting line for each the supply contact point.
  • the coding switch have six switch positions, so three with a fixed contact points arranged at a 120 ° pitch intended.
  • the sliding contacts of the rotatable switching element are accordingly in half the pitch, i.e. H. under each 60 ° arranged.
  • the total number of connecting lines is 12 four.
  • Coding switch according to the invention for higher numbers of Switch positions differ only in the number the fixed contact points and the angle at which the sliding contacts of the rotatable switching element are arranged are. Accordingly, a coding switch according to the invention with eight switch positions evenly over the circumference distributed four fixed contact points while a coding switch with ten positions five fixed contact points having.
  • the invention is in a variety of electronic devices can be used with advantage, where a setting by a User.
  • a setting by a User Form a preferred application electronic overcurrent releases for low-voltage circuit breakers.
  • the substrate as a circuit board for the printed circuit of the electronic Overcurrent release be formed during the rotatable switching element by an adjusting element for the value of a Trigger parameter is actuated.
  • circuit board of an electronic device at the same time as a carrier of the contact points and conductor tracks one Coding switch and as a pivot bearing of a rotatable contact member is known per se and is e.g. in EP 0 050 861 described.
  • a contact scheme for the coding switch corresponding to FIG. 5 4 shows FIG. 6.
  • the coding switch 1 shown in Figure 1 has a Fixed substrate 2 arranged in uniform division Contact points 3, 4 and 5. At the center of the circular The arrangement of the contact points 3, 4 and 5 is the substrate 2 provided with a through opening 6, which for receiving a pin-like setting member 7 for a rotatable switching member 10 serves ( Figure 2). Concentric to the through opening 6 is an annular one on the substrate 2 Supply contact point 11 with which the switching element 10 constantly is engaged. Furthermore, the switching element 10 has three Sliding contacts 11 on that in half the division of the fixed Contact points 3, 4 and 5 are arranged, d. H. in the present Fall below 60 ° because the division of the fixed contact points Is 120 °.
  • Each of the contact points 3, 4 and 5 and the lead contact point 11 are connected in a known manner by a conductor track 12 to an evaluation circuit which checks and evaluates connections defined by the respective position of the switching element 7.
  • 5 shows the contact scheme in the form of a table. The six different switching positions of the rotatable switching element 7 are in this table in the left column Position 0 to 5 ". The following columns indicate the contact at the individual contact points 3, 4 and 5, which are illustrated by a reduced representation with the respective highlighting of the respective contact point. In the columns relating to the individual contact points are with 1 "the existing and with 0 "denotes the non-existent contact with the switching element 7.
  • a coding switch is a further exemplary embodiment in FIG shown for eight positions.
  • the coding switch 13 has four fixed contact points 14, 15, 16 and 17, which cooperate with a rotatable switching element 18.
  • the Switching element 18 in turn has three sliding contacts 20 which in the half division of the contact points 14, 15, 16 and 17, d. H. are arranged at an angle of 45 °.
  • Conductor tracks 12 on the substrate 2 serve in the same way as already explained on the examination and removal of the respective Switch position.
  • a coding switch is a further exemplary embodiment in FIG 21 illustrates for ten switch positions.
  • the coding switch 21 therefore five fixed contact points 22, 23, 24, 25 and 26 in Connection to a rotatable switching element 27.
  • the three Sliding contacts of the switching element 27 are in turn in the half division of the fixed contact points, in this case arranged at an angle of 36 °.
  • the contact scheme of the coding switch 21 according to FIG. 4 is shown in FIG. 6.
  • the structure of this corresponds to the table according to FIG. 5, with the switch positions with Positions 0 to 9 "and additionally with a symbolic representation for the position of the rotatable switching element 27.
  • the respective affected fixed contact points are illustrated in FIG. 5 as a reduced representation of the arrangement of the fixed contact points with emphasis on the affected contact point. How to recognizes, there is a clear combination of contact assignments of the fixed contact points 22 - 26 by the rotatable switching element 27 for each switching position, which can therefore be evaluated by a logic circuit.
  • Coding switches according to the invention are suitable, as already mentioned in the introduction, for use in numerous electronic Devices where it matters that a user can select predetermined fixed setting values, for example a temperature, a current or a voltage.
  • the coding switches explained have proven to be suitable for use in electronic overcurrent releases for low-voltage circuit breakers.
  • the substrate 2 serves as the substrate 2 a circuit board on which the printed circuit of the overcurrent release.
  • the coding switches have the task here is to set the values of certain parameters, e.g. B. the amount of current at which a trip to be held. It may also be desirable to determine Assign a delay time to triggering operations, or one earth leakage current leading to tripping.
  • the adjuster 7, according to the figure 2 in the through opening 7 of the substrate 2 can be engaged, forms itself the control element to be handled by the user or with one connected by means of a simple coupling his.
  • the fixed contact points and the supply contact point are also part of the applications mentioned the printed circuit. To make contact as safe as possible to ensure that the fixed contact points, the lead contact point and the rotatable switching element be gilded.
