Definitions

  • the invention relates to an electrical switch with a mounted in a housing, acted upon by pressure and rotation actuator, which is connected via an axis of rotation with a frontally arranged detection device for the rotational movement in combination.
  • an electrical switch which serves for the luminous range regulation of headlamps of a motor vehicle and the roller-shaped actuating element is rotatably mounted about its longitudinal axis.
  • the rotation of the actuating element is limited in this switch, since the headlights may only be pivoted by a certain angle.
  • a pressurization of the actuating element for the realization of further switching functions is not provided.
  • a switch of the type mentioned by its use in a computer mouse is known.
  • the wheel-shaped actuating element a so-called scroll wheel, is used for screen control and can be acted upon by rotation or pressure.
  • the actuating element is respectively frontally mounted in a housing of the computer mouse both rotatable and vertically displaceable in the pressure direction.
  • the actuating element is located in a support device, under which a micro-switch is arranged. Due to the superposed arrangement of actuator, support device and micro-switch, this switch has a relatively high construction.
  • EP 0 901 262 A2 an electrical switch with a pivotally mounted and rotatably mounted in a housing, acted upon by pressure and rotation actuator which is rotatably mounted in a pivotable switching frame.
  • the object is achieved in that the axis of rotation is rotatably and pivotally associated with one end face of the actuating element and the detection device.
  • the axis of rotation is in the manner of a ball joint with at least one peripheral surface for transmitting a Rotary movement connected to the actuating element and able to transmit the rotational movements of the actuating element lossless both in a pressurized as well as in an unbeaten position on the detection device.
  • the Erfssungs adopted be fixed and does not follow the movements of the actuating element, whereby the electrical connection of the detection device is easy and reliable to accomplish.
  • the axis of rotation is in each case provided at the end with a polygonal condyle, in particular a hexagonal condyle.
  • a polygonal condyle in particular a hexagonal condyle.
  • its longitudinal extension of the condyle and thus its peripheral surfaces is rounded to compensate for corresponding movements of the actuator can, and in cross section of the condyle as a polygon, in particular a Haxagon, formed so that the rotational movements of the actuating element are reliably transferable.
  • the axis of rotation passes through the actuating element.
  • the actuating element in the detection device adjacent to the end face a franking for the axis of rotation and in the opposite end face a receptacle for the associated condyle of the axis of rotation. Accordingly, the axis of rotation moves due to their length at a relatively large linear lifting movement of the actuating element only by a relatively small angle relative to the longitudinal axis of the actuating element.
  • the axis of rotation is preferably guided in a housing wall extending between the detection device and the actuating element.
  • the axis of rotation can therefore be corresponding to the movement of the actuating element, which is carried out by the pressurization, shift and rotate, but is prevented in further movements.
  • the axis of rotation for guiding in the housing wall on a disc which is integrally formed in the region of the detection device associated condyle and rotatably and slidably received in a corresponding groove in the housing wall.
  • the actuating element In order to position the actuating element within the switch, the actuating element is advantageously rotatably mounted in a linearly displaceable by pressurization bearing housing. To realize a precise rotational movement, the actuating element has cylindrical projections on its end faces, which engage in corresponding bearing recesses of the bearing housing. To accomplish a simple storage for the caused by the pressurization of the actuating element displacement of the bearing housing, the bearing housing is preferably provided with guide webs which extend perpendicular to the longitudinal axis of the axis of rotation and engage in guide grooves of the housing walls.
  • the bearing housing acts upon a pressure actuation of the actuating element arranged on a printed circuit board switching element, wherein the printed circuit board between a base of the Housing and the bearing housing extends.
  • the detection device is fixedly arranged within the housing. This simple and reliable method of attachment is possible by the pivotal mounting of the axis of rotation.
  • the fixed arrangement eliminates flexible cables for electrical coupling of the detection device with the electrical system, as is known from the prior art.
  • the detection device is designed as an encoder.
  • the coding device comprises a potentiometer, a coding wheel with an associated detection device or an encoder with an associated decoder
  • the electric switch is installed in a spoke 1 of a steering wheel 2 in the vicinity of a steering wheel rim to activate a control of an on-board computer of the motor vehicle by pressing in accordance with arrow 3 of a roller-shaped actuating element 4, which is partially covered by a panel 5 and a navigation by making a menu of the on-board computer by a subsequent rotation in accordance with arrow 6 of the actuating element 4 in one or the other direction, with a confirmation of a selected menu item is made by pressing the actuating element 4 again.
  • a use of the switch in connection with an audio or air conditioning or a mobile phone, in particular with the phone book, conceivable.
  • the actuating element 4 at each of its end faces 7 a cylindrical projection 10 which engages in a corresponding bearing recess 8 of a bearing housing 9 which is mounted linearly displaceable at a pressurization of the actuating element 4.
  • the bearing housing 9 with guide webs eleventh provided, which extend perpendicular to the longitudinal axis of the actuating element 4 and engage in guide grooves 12 of the housing walls 13.
  • detecting means 14 At the parallel to the right side end face 7 of the actuating element 4 extending housing wall 13 cooperating with the actuating element 4 for detecting rotational movements detecting means 14 is fixed, which electrically contacts a arranged below the bearing housing 9 printed circuit board 24.
  • a rotary part 16 of the detection device 14 engages an end 15 of the actuating element 4 on one side projecting axis of rotation 17, which is inserted into a coaxial with the longitudinal axis of the actuating element 4 extending blind bore 18.
  • hineinerhalnde receiving 19 for the other end 15 of the rotation axis 17 is provided within the actuating element.
  • each end 15 of the rotation axis 17 is formed as a hexagonal joint head 20, wherein the individual surfaces 21st each condyle 20 describe a convex curvature from the free end of the condyle 20 to a constriction 22.
  • a disk-shaped Anformung 23 is integrally formed with the axis of rotation 17, in which the detection device 14 supporting Housing wall 13 is slidably mounted and rotatable.
  • the actuating element 4 Upon pressurization of the actuating element 4, this is moved together with the bearing housing 9 in the direction of the printed circuit board 24, wherein the bearing housing 9 contacts a housed in a dome 25 of an elastic switching mat 26 switching contact for closing a corresponding current circuit. In this position, the actuating element 4 is located in the receptacle 19 within the actuating element 4 condyle 20 is relatively below the detection device 14 associated condyle 20, wherein due to the polyhedral shape of the rod ends 20 rotational movements are transferable.
  • a return movement of the actuating element 4 takes place in its unbolted starting position due to the action of the switching mat 26 and arranged in the receptacle 19 within the actuating element 4 condyle 20 assumes a position relatively above the detection device 14 associated condyle 20 a ( Fig. 1 . 3 ).
  • a rotary movement of the actuating element 4 via the rotation axis 17 to the detection device 14 can be transferred.
