- the invention relates to a monostable electrical switching device with a housing with a base, with an actuating element for loading at least a contact point that is associated with a movable contact and at least two fixed contacts is formed, as well as with connecting contacts that with the collaborate with regular contacts.
- Monostable electrical switching devices are often found as so-called rocker switches Application in switching devices for electrical devices in motor vehicles, for Example for seat adjustments, mirror adjustments, sliding / lifting roofs, in Household, for example for armchair and bed adjustments, and in household appliance technology and consumer electronics. In all use cases it is about a to generate short-term, in particular pulse-like electrical signal.
- the known rocker switches are designed such that on a rocker side or an electrical function as opening or on both rocker sides is provided as a make contact.
- this will the functions are also divided into two or more buttons, for example for picture or Sound recording devices the functions forward or rewind and playback.
- Such known switching devices have no or at least no pronounced Switching point, which uses tactile detection of the respective switching stages allows the user, or these switching devices require an extraordinary Assembly effort that runs counter to economical production.
- the movable contact is each contact point designed to be displaceable and acted upon by a return spring in its rest position.
- the actuating element is a pivoted rocker switch trained and provided with a switching pin that the movable Contact is assigned and this acts against the force of the return spring.
- each switching device at least in each switching device a first and a second contact point provided by a common Shift rocker are actuated. This ensures that when the Shift paddle in one direction requires two different switching operations take place, which are triggered by the rocker switch by the assigned moving contacts are successively acted on by the rocker switch. Under The contact point here is that of the moving contact and the associated one solid contacts formed unity understood.
- each switching device is with four contact points each assigned to each other in pairs equipped at least two fixed contacts, so that the Switch rocker at least two switching operations are possible. So it allows this Design, the switching options of the device by operating with a Exhaust the rocker switch.
- the movable contacts of the first contact points are opposite each other slidable to the movable contacts of the second contact points arranged so that their displacement takes place relative to each other.
- the actuating element engages over the housing of the switching device, so that the switching device this is splash-proof and ensures good functional reliability is. In particular, this prevents the contacts from being impaired.
- connection contacts in the base of the housing is inserted or injected, whereby according to one preferred embodiment, the housing-side ends of the connection contacts extend into the housing interior and serve as fixed contacts.
- circuit board inside the housing arranged, which receives the fixed contacts, with the housing side Ends of the connection contacts extend into the interior of the housing up to there Extend printed circuit board and with the fixed contacts arranged thereon are connected.
- the fixed contacts are contact surfaces educated.
- each Locking cams arranged between the fixed contacts assigned to a contact point are which locking cams work with the associated movable contact and in each switch position a click on the rocker switch transfer.
- the movable contact of each contact point formed by a contact bridge the at least when switching two fixed contacts of the contact point electrically connected respectively are separated.
- Each is in the sense of an improved shift feeling Provide contact bridge with indentations that work together with the locking cams.
- Fig. 1 is a switching device 10 according to the invention with a housing 12 with a base 14 shown in cross section along section line II-II of FIG. 2.
- the rocker switch 16 shown in FIG. 2 is omitted, as is the plug-in connection molded onto the base 14.
- Fig. 2 illustrates an example of an embodiment of the invention Switchgear 10 in the rest position, which corresponding here in longitudinal section Section line I-I is shown in Fig. 1.
- the switching device 10 shown in FIG. 1 there are initially one on the base 14 Printed circuit board 15, a first contact point 20 and a second contact point 22 as well a light guide element 24 for the purpose of displaying the respective switching position or as a search light, in other words as a function or as a find light, arranged. Furthermore, one is formed on the rocker switch 16, not shown here and can be seen in this sectional illustration of the switching pin 26 shown in cross section, which serves to act on the two contact points 20, 22 and for this purpose on the one hand in pivot bearings 27, which are shown in Fig. 2, 3 and 4, and on the other hand is guided in a guide 28 assigned to two contact points 20, 22.
- Each of the two contact points 20, 22 is designed in the same way, but in the opposite direction, arranged quasi symmetrical to each other. They each have one Sliding contact 30, 32 as a movable contact, which on the with the four, only 2 to 4, fixed contacts 34 populated circuit board 15 in parallel is slidably guided to the longitudinal axis of the housing 12 and each by one associated return spring 36 in the rest position of the contact point concerned 20, 22 is acted upon.
- the aforementioned fixed contacts 34 are each connected to connecting contacts 38, which are guided by the plug connector 18 through the base 14 and on the Connect circuit board 15.
- the connection of the connection contacts 38 provided in one piece with the fixed contacts 34.
- Switching device 10 only a single switching pin 26 for actuating the first and the second contact point 20, 22 are provided. So-called control cams are used for this 40 attached to the switching pin 26 on opposite sides. These control cams 40 work with both sliding contacts 30, 32 provided contact guides 31 so that they fit together one from the rocker switch 16 to the one in a corresponding sleeve 42 guided longitudinally and acted upon by a compression spring 44 Switch pin 26 transmitted pivotal movement according to the pivot direction only the sliding contact 30, 32 assigned to this pivoting direction take.
- the automatic reset takes place.
- the return spring 36 associated with the relevant sliding contact 30, 32 both for resetting the sliding contact 30, 32 and for resetting of the switching pin 26 and thus for the resetting of the rocker switch 16.
- the switching pin 26 When pivoting the rocker switch 16 and thus the switching pin 26 in the In the opposite direction, the switching pin 26 is released from the positive connection with this movable contact 30, 32, for example that of the first contact point 20 assigned sliding contact 30, and instead engages the positive Sliding contact 32 of the second contact point 22 and takes it along.
- Snap-on cams 46 formed on the contact guide 31, which are attached to the relevant one Slide contact 30, 32 arranged detent mark 48 work together, serve to achieve a tactile shift feeling that is felt when actuated, that means when switching from switch position 0 to switch position 1 or from switch position 1 to switch position 2, on the switching pin 26 and transmits from this to the rocker switch 16.
- This tactile signal will by the person carrying out the operation as a kind of feedback of the completed Switch actuation perceived accordingly.
- the light guide element already mentioned 24 arranged, which with a on the base 14 or on the circuit board 15 arranged light source 25, for example a light emitting diode, works together and depending on the wiring as position light or to display the respective Switch position, for example in connection with a color change, is used.
- This display can be translucent or translucent due to the overall or locally Shift rocker or by a arranged in the rocker switch 16, here window not shown can be recognized from the operating side.
- the Rocker switch or the window with a symbol or a word be provided.
- the housing 12 and the Base 14 executed in two parts. Instead, however, can also with appropriate Pressing tool can be provided in one piece.
