Definitions

  • the invention relates to a switch arrangement with at least two rotary switches according to claim 1.
  • Switches of the aforementioned type are in particular provided to select different operating modes or different temperatures of an oven control and to generate commands in the form of the respectively set operating modes, coded electrical signal patterns or pulses for an incremental temperature controller and to an electronic control - or control circuit, e.g. in the form of a microcontroller.
  • the signal patterns for the electronic control or regulating circuit are each generated by means of a contact bridge grinder adjusted in accordance with the various switch positions, which grinds correspondingly coded contact tracks, preferably applied to contact disks.
  • the inventive coaxial combination of two rotary switches that are otherwise to be arranged next to one another in the control panel to form a multiple rotary switch with rotary shafts that are concentric with one another makes it possible to reduce the size considerably, but in particular in the case of an arrangement of the control handles staggered concentrically in the direction of the rotary shaft, the rotary handles are nevertheless simple due to their different handling-side diameters and safe operation is guaranteed.
  • the compactness of the entire switch arrangement can be further increased, in particular with regard to its axial compactness, by the fact that only a single contact disk is provided for at least two switches, the contact tracks or contacts assigned to each of the two rotary switches either on a different end face or concentrically with one another only one same end face of the single contact plate are arranged.
  • FIG. 1 shows a multiple rotary switch with a first rotary switch 1 for setting different operating modes of an oven and a second rotary switch 2 concentrically arranged or operable for setting different temperatures of the oven.
  • the controls of the two rotary switches 1 and 2 are arranged on the front of an operating panel 10.
  • the adjusting movement of the first rotary switch 1 is transmitted via a first rotary shaft 1.1 in the form of an inner shaft and the adjusting movement of the second rotary switch 2 is transmitted via a concentric second rotary shaft 2.1 in the form of a hollow shaft surrounding the inner shaft.
  • the rotary shafts 1.1 and 2.1 are inserted through a through opening in the front control panel 10.
  • a contact bridge grinder 5 is in contact with the first rotary shaft 1.1 via a driving part 5.1
  • a contact bridge grinder 6 is in rotation with the second rotary shaft 2.1 via a driving part 6.1.
  • the contact tracks contain coded, circumferentially distributed, mutually contact-connected contact grinding surfaces, which can be connected via the contact bridge grinder 5 to a potential to which an inner contact grinding surface running over the entire circumference is connected.
  • the contact bridge grinder 5 is in contact sliding contact with contact tracks 3.1 of a contact disk 3 and the contact bridge grinder 6 is in contact sliding contact with contacts 4.1 or contact tracks of a contact disk 4.
  • the contact bridge grinder 6 Depending on the position of the contact bridge grinder 5 relative to the coded contact grinding surfaces of the contact tracks 3.1, there are specific signal patterns at the outputs of the contact tracks 3.1, which are preferably passed on to input pins of a control circuit, in particular in the form of a microcontroller, and there can be defined as certain set operating modes; Similarly, the contact bridge grinder 6 generates 4 pulses when grinding the contacts 4.1 or its inner contact grinding surfaces of the contact disk, which pulses are preferably used for switching edge-sensitive logic inputs of a microcontroller for an incremental temperature controller.
  • the contact tracks 3.1 and contacts 4.1 of the contact disks 3 and 4 are an integral part of a circuit board 9 of the further control circuit, the contact disk 4 on the front of the circuit board 9 and the contact disk 3 shown in FIG. 1 for visualization with the rear turned toward the front is applied to the rear of the printed circuit board 9.
  • a power switch 7 is also integrated with the switch arrangement shown in FIG. 1, by means of which the supply voltage can be applied to the entire control system before the actual operating modes are set; for this purpose, the first rotary shaft 1.1 of the rotary switch 1, which is designed as an inner shaft, is advantageously extended via the contact disk actuation 3; 5 and actuates spring contacts 7.2 when the first rotary switch 1 is rotated by means of switching cams 7.1 in the sense of switching the mains voltage on or off .
  • the operating modes which can be set with the first rotary switch 1 can be fixed in their respective end position by means of a fixing part 8 which can be driven by the extended first rotary shaft 1.1.
  • the rotary shaft 1.1 rotates a locking star 8.1 which can be positively plugged onto the switch holder and which fixes the setting position of the rotary switch 1 when a locking cam 8.2 is pressed radially by a spring 8.3 into notches in the locking star 8.1 a contact code corresponding to the operating mode between the contact bridge grinder 5 and the contact grinding surfaces of the contact tracks 3.1 Contact disk 3 is generated.
  • the fixing part 8 - as can be seen in particular from FIG.
