Definitions
- the invention relates to a rotating resistor according to the preamble of claim 1.
- Rotary resistors of this type are often used in vehicle technology.
- a speed control device in which Resistance tracks are arranged on a rotating pulley. Via connection flags the electrical connection to two grinders takes place outside the housing.
- This Control device is a compact unit that acts as a rotating resistor on and in printed circuits is not usable. In addition, this facility is missing nice look necessary for the interior of a vehicle.
- DE 35 33 056 A1 discloses a light guide body connected to an adjusting handle, which has an eccentric light source arranged by the Light guide body is run over, the light guide body selected on the other hand Symbols assigned to switch positions are illuminated. This execution is complicated and allows only a small adjustment angle.
- the object of the invention is to create a generic one Rotary resistance to be carried out so that with direct contact with the electrical Line connections a light display of the actuation position is possible that a compact design as an easy-to-use module and also a pleasing one Appearance can be achieved.
- Fig. 1 shows a longitudinal section of the rotary resistor 1 according to the invention, the part a control element housing 2 is formed and a rotatably arranged Has actuating button 3.
- the actuation button 3 has one or more resistance tracks 4, which are directly on an end face 5 to be provided, or, as shown, on a substrate 6 are arranged, which with the operating button 3, z. B. is connected by gluing. At Rotation of the operating button 3, the resistance tracks 4 are rotated.
- a circuit board 7 is arranged within the control element housing 2 Has conductor tracks 8, the electrical line connections, not shown are provided.
- one or more contact springs 9, for. B. by jamming, Riveting or soldering with the existing on the circuit board 7 traces 8 are connected and under their resilient action with contact surfaces 10 against the Create resistance tracks 4.
- control button 3 has a light guide body 11 in the The embodiment shown carries the substrate 6 with the resistance track 4.
- this light-guiding body 11 has a light entry surface 12, in front of which one Light source 13 is arranged, which is connected to the circuit board 7 via connecting lines 14 is connected and is turned on when the operating button 3 is pressed, so that the Actuation button position on a scale of a transparent housing part 15, in which the light guide body 11 protrudes with its peripheral part, is recognizable, d. H. a not shown reference point, for example an arrow of the operating button comes with the Scale in relationship.
- the housing part 15 can also be a light guide body 16 have, which leads the light directly to the scale of the housing part 15.
- FIG. 2 shows a rotary resistor 1 according to FIG. 1, which can be used as a module Component 17 is designed in which a base body 18 for receiving the individual Components is provided, a support surface 19 and snap tabs 20 for the bracket the circuit board 7, a bearing surface 21 and a radial bearing 22 for storage of the actuating button light guide body 11, which with its outer wall 23 transparent housing part 15 picks up with the scale and secured by snap noses 24 and furthermore snap noses 25 for control element walls 26 on the outer wall has and snap noses 27 for an aperture ring 28, the transparent Housing part 15 with an inner collar 29 the actuating button light guide 11 axially backs up.
- Fig. 1 shows the contact springs 9 in a soldering to the conductor tracks 8 and Fig. 2 in a jam within an opening 30 of the circuit board 7.
- the invention is not limited to these statements. It can too Multiple contact spring arrangements are made, which is due to the imaginability individual are not shown.
