Definitions

  • the invention relates to a rotary switch according to the features the preamble of claim 1.
  • Such a rotary switch is used for example for the setting the lighting of a motor vehicle needed.
  • the mode of operation of such a rotary switch is, for example also known from DE-U1-71 14 793.
  • a multi-stage switch is known from DE-A-1 102 242 that has two housing halves. Within the A camshaft is rotatably supported over the housing halves which a shift lever can be actuated. The shift lever is actuated in turn the contacts.
  • the invention has the object of an inexpensive Switch to create a variety of electrical Is able to switch contacts at the same time while doing so a large number of contact combinations depending allowed from the position of the rotary lever.
  • the housing is divided into at least two housing parts, each with its own contact arrangement are, the individual contact arrangements by a common camshaft can be actuated. That way it is possible, on the one hand, within the individual housing parts to create a comparatively inexpensive contact arrangement, then assemble these contact arrangements and this Contact arrangements via a single twist grip at the same time to operate. Which contacts of the individual contact arrangements then within which rotary position of the rotary handle operated depends on the design of the cams on the common camshaft. A particularly simple one Construction is obtained according to the invention through use of two housing halves. In principle, however, the invention is can also be used for other housing parts that radially around the common camshaft can be arranged.
  • part of the camshaft is longitudinally displaceable, while another part is fixed in its longitudinal position and is only rotatably arranged.
  • One is with nocks provided cam sleeve only rotatably arranged, while this cam sleeve with one extending into it
  • Rotary shaft is provided, which is also movable Contact-controlling protrusions.
  • the rotating shaft is in the Switch housing and in particular in the cam sleeve lengthways displaceable, but arranged to rotate with it, so that regardless of the longitudinal position of the rotary shaft relative to the Cam sleeve by rotating the rotary shaft the cam sleeve is taken away.
  • the two Housing parts locked together by locking means of a housing part on locking means of the other housing part attack. It is possible that the locking means one Housing part each the locking means of the other housing part reach from outside. There is another possibility in principle in that the two housing parts at least with regard the locking means are constructed symmetrically, so that once the locking means of a housing part outside and once from the inside on the locking means of the other housing part attack.
  • a contact arrangement includes at least one housing-fixed Contact and a moving contact that is dependent from its location an electrical connection to the creates fixed contact. But there can also be several to each other parallel movable contacts with the help of a corresponding Number of cams on the camshaft at the same time or operated depending on their angular position. At the same time, using a single movable contact a connection from one fixed contact to several stationary contacts depending on the angle of rotation the camshaft are created. So it's with With the help of the switch according to the invention a large number of Switching combinations possible by using the in two levels (housing parts) arranged contact arrangements can be reproduced.
  • the combination of features according to claim 4 are dependent on the projections on the rotating shaft and of their longitudinal and angular position in one or more the housing parts of the plunger are mounted so that they can move radially (Actuating pins) moved, which is the result of a A suitable rotary and / or longitudinal movement of the rotary shaft Carry out radial movement.
  • the radial movement serves as a suitable one Control of the movable contacts against fixed Contacts so that depending on the longitudinal and angular position of the rotating shaft controlled, i.e. opened or getting closed.
  • the invention allows a particularly simple structure of the Fixed contact banks by using the combination of features according to claim 6. Then the stationary contact pieces at least partially with the associated housing part shed.
  • the contact pieces can be made from a single Sheet metal to contact strips running essentially parallel to each other punched out and then with the associated housing part be partially shed. You get a stable one and moisture-proof mounting of the fixed contacts in the associated housing part, whereby by a kinked Laying the fixed contacts within the potted Section of great strength at least the Pin connections of the fixed contacts can be reached.
  • claim 7 for the movable Contacts (contact tongues) of the rotary switch according to the invention.
  • a good anchorage of the stationary can be achieved Ends of the tongues inside the housing parts Achieve shedding.
  • the leading to the connection knives Contact tracks of the contact tongues can correspond to the fixed contact pieces.
  • the housing is also used for a split bearing, which is for preventing longitudinal displacement necessary with simultaneous turning possibility Undercuts between the bearing and cam sleeve in simple Way.
  • the split design of the switch allows at the same time to use the features after Claim 9. This is through the two housing halves covered rest area formed with a rest contour, the corresponding on the rotary shaft arranged locking means latching locking both with regard to the longitudinal position the rotary shaft, as well as in terms of their angular position allowed.
  • This rest area thus has several to each other parallel substantially annular locking contours that the Specify the longitudinal position of the rotary shaft.
  • the essential circular contour are recesses or projections are provided such that for the locking means the rotary shaft certain preferred angular positions result in which the rotary shaft engages during the turning process.
  • the two housing halves can be connected to each other by locking. In many cases, however, it will be advisable to add an additional one enclosing housing shell according to the Feature combination according to claim 10 provide. That recommends especially when the two housing halves in the are essentially symmetrical to each other, so that they act against each other despite the radially engaging Latching means displaceable in and in the tangential direction Direction are also mergable. In this case, back up the housing sleeve from a tangential movement of the two housing parts against each other.
  • the housing sleeve itself can be made up of several interlocked sections be one that runs transversely to the longitudinal axis of the camshaft Possess division level.
  • the switch according to the invention is parallel by the two mutually cuboid housing parts Can be set up very space-saving. If this is desired but can the housing towards the handle, for example circular cylindrical, expand.
  • the space created in this way for example to accommodate the rest area mentioned above can also be used in further training according to the invention for receiving a circuit board use the combination of features according to claim 13.
  • An essentially annular printed circuit board is thus obtained, which lie in a transverse to the longitudinal axis of the rotary shaft Is arranged plane and symmetrical to the longitudinal axis.
  • Suitable components such as Setting potentiometers, lamps, connecting lines, etc. accommodate, the filament parallel to the longitudinal direction the rotating shaft can be arranged.
  • the connector pins can claim accordingly 15, like the contact pieces or the contact tongues themselves be led out of the associated housing part, so that the circuit board facing away from the operator End of the switch can be powered, which over parallel to the contact tracks in the same plane as this running conductor tracks is supplied with electricity.
