Definitions
- the invention relates to an electrical toggle switch with a button mounted on a housing, the one Actuator assigned to act on a switching element is.
- an electrical key switch is known the housing with a switching element at least one automatically resetting and off-center stored button is provided.
- an actuator is formed on the button, that interacts with an assigned snap disc, which both resets the button and is used to connect current paths on a printed circuit board.
- a disadvantage here is that the limited Travel of the snap disk is only a relatively short one Switching path of the button is realizable and in the event of an overstroke the button the circuit board due to an excessive application force can be damaged.
- DE-U-76 34 027 discloses a momentary switch, whose electrical contacts via a one-sided Button with an associated, slidably mounted Actuation approach can be acted upon. This is the way of actuation the key from the switching path of the assigned contacts dependent. There is also a dependency between the Contacts and the counterforce that the actuator of the actuating force the key opposite.
- DE-A-197 26 529 shows an electrical key switch with a housing in which a switching elements Contact unit is arranged, and with at least an automatically resetting and off-center Key with an actuator acting on the switching elements, which is molded onto the button.
- This is the Contact unit resiliently mounted in the housing and against excessive Force applied by the actuator to the switching elements compliant, being between the contact unit and the base the housing a spring unit is arranged.
- a counterforce the actuating force of the button is activated by a compression spring generated, which is between the actuator or the button and supports the contact unit. Due to the arrangement of the Spring unit between the contact unit and the base of the Housing this push button switch has a relatively complicated Building on.
- the object is achieved in that the actuator is designed as a leaf spring, one end of which is on the housing side and their other free, with the Switching element cooperating end under tension on the Button is present.
- the operating force of the button depending on the spring action of the actuator, which at the same time causes the key to be reset after it has been acted on and holds the key in its original position.
- the actuator provides a desired counterforce to the actuating force the button is available, creating a corresponding tactile Switching sensation is generated.
- the fact that the free end of the actuator designed as a leaf spring on the switching element acts, the switching element is in front of an overstroke button-related overload, when the button is pressed can be stamped, protected because the leaf spring in the elastic range is compliant.
- the switching element is preferably designed as a microswitch and arranged on a perpendicular to a bottom of the housing PCB attached, with the PCB in the inside of the hollow button extends.
- the toggle switch a very compact structure with more reliable How it works.
- the PCB should also be fixed exactly to the housing held between guide lugs of the housing.
- the guide lugs are integrally formed on the housing and are manufactured together with this in the injection molding process.
- the key is expediently by means of an opposing one and spaced apart mounting brackets, which are in the Stretch inside the button, stored.
- the bearing brackets are also integrally formed on the housing and act as they are inside the button, optically not annoying.
- the button is molded onto an attachment on which the free end of the actuator is present.
- the approach represents an exact transfer the actuating force acting on the button on the actuator and thus also on the switching element.
- the actuator is preferably essentially U-shaped, one leg attached to the circuit board is the other leg that acts on the microswitch is supported on the base of the button and the leg connecting web is inclined in the direction of the microswitch.
- the distance between the parallel legs of the U shape is on the one hand to the height of the microswitch and on the other adapted to the actuation path of the button.
- the inclination of the Steges essentially influences the counterforce that the actuator opposed to the actuating force of the button.
- the free end of the actuator is expediently provided with a Angle to the linear contact of the microswitch Mistake. Furthermore, the free one preferably extends End of the actuator beyond the approach of the key. With one Overpressure of the button bends the one assigned to the microswitch Leg in the support area of the approach of the button through, which is why there is a risk of damage to the microswitch and the associated circuit board is relatively low.
- the actuator is preferred in relatively large quantities punched in one piece and shaped accordingly.
- This The actuator can be manufactured using a progressive tool with relatively small tolerances.
- toggle switches of this type are rarely used used alone are preferred. This measure reduces the Installation effort of several toggle switches considerably, since only the connection contacts of the common circuit board must be electrically connected. Conveniently the keys are parallel and spaced apart stored on the housing. This makes tactile easier Detection of the individual keys of the toggle switch is guaranteed.
- a steering wheel 1 comprises a steering wheel rim 2, which spokes 3 is connected to the steering wheel bowl 4. On each Side of the steering wheel 1 is between adjacent spokes 3 one each consisting of several toggle switches 6 Switch unit 5 inserted into the steering wheel bowl 4. The Switch units 5 are connected via connecting lines 7 common connectors 8 for coupling the toggle switch 6 in connection with an electrical system of a motor vehicle.
- Each toggle switch 6 is common to one Housing 9 stored key 10 provided on the operator facing side a back-lit symbol 11 carries and the end facing away from the operator as Actuating surface 18 is formed.
- the button 10 has the housing 9 opposite to each other spaced bearing tabs 12, which are located inside the hollow button 10 extend, the bearing tabs 12 on their free ends in corresponding holes 14 of the key Wear 10 engaging pins 13.
- an aperture 15 is provided below the 10 buttons, which is formed by means of a molded web 16 inserted into corresponding guide grooves 17 of the housing 9 becomes.
- the housing 9 with guide lugs 19 provided for holding a circuit board 20 which in Area of the button 10 of the middle toggle switch 6 of one on the top and in the area of each key 9 the toggle switch 6 is held by an underside stop 21.
- the stops 21 prevent deflection of the circuit board 20 in one direction or another.
- the leadership approaches 19 each have a groove 22 for receiving the circuit board 20 on.
- the circuit board 20 is perpendicular to a floor 41 of the housing 9 arranged and carries in the area of each key 10th a switching element designed as a microswitch 23 and an actuator 24 assigned to the microswitch 23, wherein the circuit board 20 with the microswitch 23 and the area 24 supporting the actuator 24 into the inside of the button 10 extends.
- the actuator 24 designed as a leaf spring 40 is essentially U-shaped, one leg 26 on the circuit board 20 is attached, the other, the microswitch 23rd acting leg 27 under tension on a Approach 28 supports the button 10 and the legs 26, 27th connecting web 29 inclined in the direction of the microswitch 23 is.
- the leg 26 fixed to the printed circuit board 20 Actuator 24 comprises two spaced apart, via one Flange 30 interconnected arms 31 on which angled Extensions 32 for determining the actuator 24 in corresponding Bores of the circuit board 20 are formed.
- the free end of the leg 27 of the actuator 24 is one Angle 33 for linear contact of the microswitch 23 provided and extends over the approach 28th button 10.
- the switch units 5 shown are used for remote control a not shown radio of a motor vehicle, a toggle switch 6 as a memory interrogation switch 36 of the radio, two toggle switches 6 as station search switch 37 to search for a radio station in different Directions, a toggle switch 6 as a switch 38 for switching between radio and cassette operation and two toggle switches 6 as a volume switch 39 for regulating the Volume of the radio are provided.
- the operator of the radio can therefore control all functions without his hands need to take off the steering wheel 1 by using the appropriate Fingers of the right or left hand the assigned Actuating surfaces 18 on the button 10 of the toggle switch 6 acted upon. To facilitate easier tactile recognition of the individual To ensure buttons 10, they are spaced apart mounted on the common housing 9.
