Definitions

  • the invention relates to an electric rotary switch with a rotary switching element mounted in a housing, which has switching contacts for acting on switching contacts assigned to a base, the rotary switching element being coupled to an actuating element and interacting with means for determining switching positions.
  • DE 40 08 248 C1 discloses an electrical rotary switch with a housing, a switching piece that is rotatably held in the housing and can be brought into various switching positions via an actuating element, cooperates with switching contact parts present in the housing, and at least one movable latching element assigned to the switching piece and acting under the action of a spring element and a locking device arranged in the region of the side walls of the housing and cooperating with the movable locking element and having at least two locking curves, the rotary switch being constructed in such a way that other switching functions can be implemented by changing the position of at least one of its components.
  • the latching device is designed such that either the one latching curve or the other latching curve is changed by changing its position in the switch housing is assigned at least one movable locking element.
  • the switching element is provided with a switching element which produces certain switching functions in a first position and which causes other switching functions in a second position which is different from the first position and which is assigned to the switching contact parts.
  • the latching device is assigned two movable latching elements which are held diametrically displaceably in a recess in the switching piece and are under the action of a helical compression spring. This rotary switch has a relatively complex structure and requires a large installation space.
  • an electrical switch in particular a rotary switch, is known, the electrical contact elements of which can be influenced by means of an actuating element, which in turn is assigned to a latching device which interacts with the latching curve from a latching curve and at least one spring-loaded curve Latching element exists and can be brought from a latching rest position into at least one working position.
  • the locking curve of the locking device has the shape of a logarithmic spiral of a certain type.
  • DE 198 12 251 C2 shows an electrical rotary switch with a stationary and movable electrical contact element accommodating housing consisting of a base part and a cover part, and at least one housing which can be rotated in the housing via an actuating element into several different switching positions and which can be moved in the housing
  • Contact element cooperating contact piece, at least on the rotatable in the housing se mounted contact piece at least one plate-shaped cam is available, the cams on the one hand can be actuated by actuating plungers arranged displaceably in the housing, which, on the other hand, are directly in contact with at least one of the movable electrical contact elements.
  • the plungers can only be guided in a longitudinally displaceable manner on the movable contact elements by means of guide recesses in the base part of the housing, and the plungers to be actuated by the cams are articulated integrally on a control disk via thin, flexible connecting webs as one-piece components.
  • the object is achieved in that the means for determining switching positions are assigned on the one hand to the end face of the rotary switching element pointing in the direction of the base and on the other hand to the base.
  • the rotary switch Because of the axial alignment of the means for determining the switching positions of the rotary switch in the area of the rotary switching element, the rotary switch requires only a small installation space, which is essentially determined by the dimensioning of the rotary switching element.
  • a locking sleeve that is loaded with compression springs in a first dome of the rotary switching element and is provided with at least one indentation or opening on the base side sloping surface interacts. Due to the different design of the base, namely on the one hand with indentations and on the other hand with bevels, either latched rotary switches or momentary rotary switches can be manufactured with identically designed rotary switching elements. The number of indentations on the base determines the number of switch positions. The run-up slope of the rotary switch gives the user a tactile tactile feel.
  • the rotary switching element has a relatively simple structure.
  • the geometry of the switch contact corresponds to that of a section of a circular ring in order to bridge switch contact tracks, for example a lead frame or a printed circuit board, associated with a rotary movement of the actuating element or of the rotary switch element.
  • the assigned switching functions cause, for example, dimming an instrument lighting of a motor vehicle or a height adjustment of motor vehicle headlights.
  • the rotary switching element is expediently provided with a recess for the rotationally fixed reception of the actuating element.
  • an engaging nose in the recess is advantageously molded onto the actuating element.
  • the actuating element is mounted such that it can move axially in such a way that in the lower end position it is flush with an upper edge of the housing and in the upper end position it projects above the upper edge of the housing.
  • This type of axial mounting of the actuating element takes place on the one hand for optical and on the other hand for functional reasons. If the actuating element is in its lower end position, inadvertent actuation of the same is excluded, for example, and further actuating elements in its immediate vicinity can be actuated without any problems, since the required free space is created for this by lowering the actuating element in the housing.
  • the actuating element is supported on the base under compression spring load and has a heart curve in which a rotary switch-fixed pin engages in order to hold the actuating element in the lower end position when pressure is applied and to release it again when pressure is applied again. Because of this configuration, the locking of the actuating element in its lower end position and its release for displacement into its upper end position is ensured by pressurization with a small number of individual parts.
  • the pin is expediently S-shaped, one end being fastened in the recess of the rotary switching element and the other end extending above the rotary switching element into the heart curve of the actuating element.
  • the heart curve is expediently formed in the nose of the actuating element.
  • the actuating element preferably has an extension which engages in the recess of the rotary switching element and whose cross section is designed as a semicircular ring.
  • a compression spring is preferably inserted into the center of the attachment, which is supported on the one hand on a web of the base and on the other hand with a cap arranged on the actuating element. The cap protects the actuating element from damage by the compression spring.
  • the cap is preferably designed as a light guide for backlighting a symbol of the actuating element.
  • the required light source can be assigned to the base, for example.
  • the extension of the actuating element in its lower end position plunges into a recess in the base in order to block rotation of the actuating element.
  • the anti-rotation protection of the actuating element is then implemented using simple means without additional components.
  • the actuating element In order to hold the actuating element in the housing, the actuating element preferably has between the attachment and a cross-sectionally cylindrical grip surface on an annular shoulder, which rests in the upper position of the actuating element on the housing.
  • the ring shoulder also limits the displacement of the actuating element in the direction of the base, since it comes to rest on the rotary switching element. This also prevents damage to the pin engaging in the heart curve of the actuating element.

  • the switch unit comprises a base 1 of a housing, to which switch contact tracks 2 of a lead frame are assigned, which lead to connection contacts for connection to an electrical system of a motor vehicle.
  • the switch unit is assigned a plurality of individual switches, of which two rotary switches 3, 4 are shown, one rotary switch 3 taking switch positions and the other rotary switch 4 taking switch positions.
  • Each of the rotary switches 3, 4 comprises an essentially circular-section-shaped rotary switching element 5, at the peripheral corner points of which domes 6, 7 are formed and in the center of which an actuating element 8 engages.
  • a compression spring-loaded locking sleeve 9 is provided in the first dome 6 of the rotary switching element 5.
  • the locking sleeve 9 interacts with a run-up slope 10 of the base 1.
  • several indentations 11 are provided on a circular path in the base 1, in which the locking sleeve 9 is inserted.
  • a cylindrical extension 12 of a switch contact 13 is held under compression spring.
  • the switch contact 13 has the shape of a circular ring section and interacts with the switch contact tracks 2 in the base 1.
  • the actuating element 8 is provided with a nose 14 Approach 15 rotatably mounted in a recess 16 of the rotary switching element 5, the extension 15 of the actuating element 8 being designed in its cross section as a semicircular ring.
  • a compression spring 17 is inserted, which is supported on the one hand on a web 18 of the base 1 and on the other hand with the interposition of a cap 19 on the actuating element 8.
  • a nose 20 is formed on the extension 15 of the actuating element 8, which engages in a corresponding groove 21 in the recess 16 of the rotary switching element 5.
  • a heart curve 23 is formed, in which one end of an S-shaped pin 24 engages, the other end of which is fixed in a bore 25 in the groove 21 of the rotary switching element 5.
  • a gripping surface 26 of the actuating element 8 which is cylindrical in cross section, protrudes over an upper edge of the housing, so that a user of the rotary switch 3, 4 can act on it.
  • the upper end position of the actuating element 8 is delimited by an annular shoulder 27 below the gripping surface 26, which comes to bear against the same within the housing.
  • the annular shoulder 27 lies on the associated end face of the rotary switch limb 5 and the projection 15 of the actuating element 8 dips into a recess 28 of the base 1, which is dimensioned such that a rotation of the actuating element 8 is blocked in its lower end position.
  • the cap 19 is designed as a light guide. The required light radiation is emitted by lighting elements 30 arranged on the base 1.
  • the rotary switch 3 with the switch positions used for switching a dimming function for instrument lighting and the rotary switch 4 with the switch positions used for height adjustment of headlights of a motor vehicle.
