Definitions

  • the invention relates to a switch, in particular a mode switch according to claim 1, or to a method for assembling such a switch according to claim 14.
  • Such switches are used in particular to select different operating modes of an oven control and to issue commands from an electronic control circuit; the respective end position set by an operating part, in particular by turning, is secured by a fixing part, in particular in the manner of a snap lock.
  • the switch according to the invention allows the control panel to use a unit component that can be used universally for all switch variants, apart from a labeling panel that may need to be adapted; a specific Adaptation to different switch variants with end settings that are specifically available or distributed and to be secured via the switch actuation path is carried out by means of a fixing part module which is only to be adapted accordingly and can be assembled with the unit control part, preferably using axial plug-in technology.
  • the switch According to the setting end positions and thus depending on the selected operating mode, the switch generates a specifically coded electrical signal pattern and passes it on to an electronic control system; For this purpose, with the switch actuation, an electrical contact bridge grinder is coded into corresponding angular positions, and a coding contact disk is distributed over interconnected contact contact surfaces, so that, depending on the position of the contact bridge grinder, specific signal patterns are generated relative to the contact tracks of the coding contact disk to a subsequent control circuit, for example in the form of a microcontroller.
  • Such an electrical contact coding in accordance with the mechanical settings of the switch can be simplified for the use of switches with different switch variants in that, according to one embodiment of the invention, a universal coding contact disk is provided with different contact path codes corresponding to all of the angular positions of the contact bridge grinder different switch variants to be covered; Expediently, all of the coded contact grinding surfaces are each non-linearly distributed over the circumference of the universal coding contact disc, such that the wiper positions corresponding to the switch positions of a switch variant can be distributed linearly over the circumference.
  • FIGS. 1, 2 each show the top view of the operating front of an oven control with an operating part 1 which can be set by rotating into different operating modes and displays arranged above the operating part 1 for the respectively set operating mode.
  • the control unit 1 according to FIG. 1 has four settings of operating modes BA1-BA4 distributed over the circumference and the control unit 1 according to FIG. 2 has six settings of operating modes BA1-BA6 distributed over the circumference in addition to a neutral position.
  • FIG. 3 shows a perspective exploded view of an operating mode switch with a rotary shaft 1.1 mounted in a base body 2, on the right end of which projects through an opening of a printed circuit board 5 arranged behind the operating front, in a manner not shown here, the operating part 1 according to FIG is.
  • On the base body 2 is at its left end - e.g. in an advantageous manner by means of axial push-on pins 2.2 - a fixing part 3 shown in more detail in FIG.
  • the respective locking position of the locking star 3.1 and thus the fixation of the operating part 1 in one of the set operating modes is ensured by means of a locking cam 3.2 which is pressed into the notches of the locking star 3.1 by radial pressure of a locking spring 3.3.
  • the base body 2 has contact tongues 2.1 for connecting a power supply line, which can be switched on and off by a roller switch located below the contact tongues.
  • the base body 2, including the rotary shaft 1.1 of the switch mounted therein, can advantageously be used as a universal component regardless of different switch variants, since different switch variants can only be taken into account by changing the locking star 3.1 by plugging in a correspondingly adapted fixing part 3.
  • the successful standardization by using universally applicable components despite covering a switch manufacture with different switch variants can be further improved with regard to a corresponding electrical or electronic signal transfer to a subsequent control, in particular in the form of a microcontroller, in that - as in particular from FIG. 6.7 evident - depending on the setting actuation of the Switch, in particular depending on the position of the rotary shaft 1.1 of a rotary switch provided for setting, a contactor 1.2; 1.3 in the form of a driver part 1.2 which can be rotatably plugged onto the rotary shaft 1.1 and has a contact bridge grinder 1.3 attached to it.
  • Contact tracks ae of a universal coding contact disk 4 grinds, the contact grinding surfaces of which are coded to the contact bridge grinder 1.3 in such a way that, according to the maximum of twenty-two individual angular positions AW assumed here, a specifically coded signal pattern in each case by contact between the individual contact grinding surfaces via the contact bridge grinder 1.3 result in the outputs of the contact tracks ae, which can be connected to input pins of a subsequent electronic control; the contact grinding surfaces which are electrically connected to one another for each contact path are set to a potential via the contact bridge grinder 1.3 to generate the Singal pattern, which is connected to a contact grinding surface running over the entire circumference of an inner contact path which is likewise ground by the contact bridge grinder 1.1 com is connected.
  • the seventh explains the coding program of the universal coding contact disk 4 shown in FIG. 6 with a maximum of twenty-two angular positions of the contact bridge grinder 1.3.
  • the uppercase letters in the table mean the individual angular positions AW of the contact bridge grinder 1.3 and the lowercase letters ae denote the coded distribution of the contact grinding surfaces or potential assignments and thus the signal pattern of the contact paths connected to the processor pins.
  • the twenty-two different codings are distributed non-linearly over 360 ° over the entire circumference of the universal coding contact disk 4, in such a way that a linear distribution of the operating modes per switch variant can advantageously be achieved for switch variants of two to eight operating modes provided here.
  • a memory in particular a non-volatile EEPROM.
  • the coding contact disk 4 is an integral part of a printed circuit board 5, which is preferably attached behind the operating front according to FIG. 1-2 and with a passage for plugging the operating part 1 onto the front the front rotating shaft 1.1 is provided.
  • a further contact disk 7 is integrated for the impulse for a serial temperature controller 6 of the oven, which is also rotated by rotating a rotary shaft 6.1 with a contactor held thereon with a positive fit 6.2; 6.3 can be actuated.
