Definitions
- Actuator for an electrical switch in particular for a motor vehicle steering wheel switch
- the invention relates to an actuating element for an electrical switch, in particular for a motor vehicle steering wheel switch, which acts on at least one switch contact and is pivotably mounted on a housing of the switch.
- the object is achieved in that a film hinge is provided as the bearing, which connects the actuating element to a wall which is latched to the housing, the wall either running parallel to a housing wall or replacing a housing wall.
- the actuating element By connecting the actuating element to the wall, it is possible to manufacture it from a suitable plastic, to which other mechanical requirements can be imposed than the material of the housing.
- a suitable plastic for example, a glass fiber reinforced plastic with high strength is used to manufacture the housing, which cannot be used with a film hinge and the visible surface of the actuating element.
- the actuating element is made with the film hinge and the relatively lightly loaded wall from an unreinforced plastic, which has the necessary elasticity and a high 0- required for the visible surfaces of the actuating element surface quality guaranteed. A relatively quick assembly is ensured by the fact that the wall can be locked with the housing.
- the wall replaces one of the housing walls, there is an additional material saving.
- the wall arranged parallel to a housing wall an increased stability of the housing is achieved.
- the choice between these two alternatives is made according to the specific requirements for the housing, such as its installation situation or mechanical load.
- a plurality of actuating elements are arranged parallel to one another perpendicular to the longitudinal axis of the housing and are connected to the wall by at least one film hinge.
- At least one locking arm is advantageously formed on the underside of the actuating element, which engages behind an extension formed on the housing wall opposite the film hinge. Since the film hinge is felt on the visible side of the actuating element looks and feels as disturbing, the wall extends into the film hinge and an actuating face of the actuating element goes out of 'the wall and / or the film hinge substantially perpendicular. The film hinge is thus assigned to the outermost edge region of the actuating element.
- One end face of the actuating element is preferably aligned flush with the wall and the associated film hinge, and the other end face engages over the housing wall opposite the wall in some areas. The entire top of the housing and the film hinges are then covered by the actuation element or elements.
- the wall is advantageously guided on the assigned covered housing wall or between opposite front housing walls.
- the guide is expediently designed as a dovetail guide.
- the dovetail guide ensures guidance in two axes and therefore ensures precise positioning of the actuating element in relation to the housing.
- a plurality of guide webs of the housing wall and corresponding guide grooves of the wall are preferably provided at a distance from one another, the guide webs extending over almost the entire height of the housing wall and the guide grooves extending over almost the entire height of the wall. On- Due to the relatively long lengths of the guides and their spacing from one another, twisting of the wall to the housing wall is almost impossible.
- At least one clip arm with a clip opening is expediently formed in the wall for the latching reception of a clip nose formed on the housing wall.
- projecting bores are provided on a base of the housing which holds the switch contact in the form of a microswitch and are provided for fixing between spokes of a steering wheel.
- the entire switch which can be used, for example, to control a cruise control, is reliably attached to the steering wheel via the holes by means of screws.
- the cross section of the housing is expediently essentially triangular, the longitudinal housing walls forming the legs of the triangle, one front housing wall the base and the other front housing wall essentially an arcuate connection of the longitudinal sides Form housing walls.
- the free end faces of the actuating elements opposite the film hinges are advantageously designed in an arc shape.
- the actuating elements are thus also adapted to the steering wheel contour.
- the switch contacts are relatively sensitive components that must be protected against overload due to excessive force when the actuating elements are acted upon. It is therefore expedient for at least one stop to be assigned to each actuating element on the side opposite the film hinge, which comes into contact with the corresponding housing wall when it is acted upon.
- a plunger assigned to an actuating element for actuating the corresponding microswitch is preferably displaceably guided on one of the longitudinal housing walls.
- FIG. 1 shows a perspective illustration of a switch arrangement with actuating elements according to the invention
- FIG. 2 shows a perspective view of a detail II according to FIG. 1
- 3 shows a further perspective view of detail II according to FIG. 1
- FIG. 4 shows a partial exploded view of detail II according to FIG. 1,
- FIG. 6 shows an illustration of a detail VI according to FIG. 5.
- the switch arrangement is used to control a speed control device, a so-called cruise control of a motor vehicle, and comprises two electrical switches 1, each with a housing 2.
- the switches 1 are connected to one another via lines 3, which lead to common plug contacts 4 for connection to the vehicle electrical system.
- two individual switches 5 are accommodated, one of which is used for switching on and the other for switching off the speed control device.
- the other housing 2 accommodates three individual switches 5, one for resetting the set speed, one for storing the current speed and increasing it, and one for reducing the current speed of the motor vehicle by means of the speed control device.
- the switches 1 are attached directly to a steering wheel, not shown, between the spokes thereof, which is why the driver does not have to remove his hands from the steering wheel when the individual switches 5 are acted on.
- Each individual switch 5 comprises a pivotably mounted actuating element 6, which is spaced apart by film hinges 7 is connected to a wall 8, the wall 8 also supporting the further actuating elements 6 assigned to the switch 1 via separate and spaced apart film hinges 7.
- the wall 8 extends into the film hinges 7 and an actuating surface 11 of the actuating element 6 provided with symbols 9 and tactile perceptible elevations 10 extends essentially perpendicular to the wall 8.
- the one end face 12 of the actuating element 6 is aligned flush with the wall 8 and thus covers the wall 8 and the film hinges 7 with the actuating surface 11.
- the end face 13 of the actuating element 6 opposite the wall 8 overlaps in some areas the corresponding housing wall 14. Since the overall width of the actuating elements 6 arranged parallel to one another spans the entire upper side of the housing 2, the housing is virtually imperceptible in the plan view of the switch.
- the wall 8 runs parallel to a longitudinal housing wall 15 and is guided thereon by means of dovetail guides 16 spaced apart from one another.
- guide webs 17 are integrally formed on the housing wall 15 and corresponding guide grooves 18 are embedded in the wall 8, the guide webs 17 extending over almost the entire height of the housing wall 15 and the guide grooves extending over almost the entire height of the wall 8.
- a clip arm 19 is formed in the wall 8 with a clip opening 20 into which a corresponding rende Klipnase 21 engages the housing wall 15.
- the cross-sectional area of the housing 2 is essentially triangular, the longitudinal housing walls 14, 15 forming the legs of the triangle, an end housing wall 22 the base and the other front housing wall 23 essentially an arcuate connection form between the longitudinal housing walls 14, 15.
- the switch 1 is fastened via projecting bores 24, which are formed on the housing 2 receiving a clipped-in base 25.
- Metallic threaded bushings 26 are inserted into the bores 24.
- the base 25 carries a printed circuit board 27 with switching contacts 29 designed as microswitches 28, each individual switch 5 being assigned a separate microswitch 28.
- a plunger 30 is provided for actuating the microswitch 28.
- the plunger 30 has a receptacle 31 which partially surrounds the microswitch 28 and which is connected to a guide surface 32 running perpendicularly thereto.
- the guide surface 32 is slidably guided in a substantially T-shaped groove 33, the groove 33 also serving to receive a compression spring 34 which is supported between the underside 35 of the guide surface 32 and the base of the groove 33.
- extensions 35 are formed on the housing wall 14, which are engaged behind by corresponding locking arms 36.
- the locking arms 36 are formed on the underside of the actuating element 6.
