The subject of the present invention is a miniature push button switch, in particular for electrical systems in motor vehicles.

As is well known. Electric buses built into motor vehicles operated devices, such as electric fans, heated rear windows, etc., operated by a switch will·

The switches that can currently be used for this purpose, on the other hand, usually have radio technology restrictions on, either due to their excessive need or to the structure of the actuator, which does not have any immediate determination of the closed or open position of the container itself allows to be retracted.

The object of the present invention is to eliminate these disadvantages by creating a small-sized push button switch with mechanical Locking in the closed position of the contacts.

There is a special goal in batmen for this task the invention in the creation of a ffi-fri atur push button switch, which has means for differentiated illumination of the key in the closed position.

Another object of the present invention is in the manufacture of a Mimatui ^ push button switch, which establishes the connection between one or more

movable contacts and two or more permanent contacts Eontakten made possible.

Another goal of the present noise link is in the production of one, especially with regard to the resistance of the joints in crocodile trees fully reliable Kmiatvuv push button switch.

which is characterized in that it has a box-shaped body with a square base, which is lamellar-like contacts on one side or on two opposite sides and a wire-shaped flexible spring with a beak on the adjacent or intermediate side. Side carries, with a substantially tubular, against the action of an elastic member and with the possibility of displacement mounted button is provided in the box-like body, which carries one or more pin contacts and a raised profile on the sides corresponding to said sides, and wherein the The same load is also provided with a foldable intermediate screen, while a light source is arranged inside the box-like body.

According to this, the miniature push-button switch according to the invention consists of a box-like body 1 with a square base, which carries lamellar contacts 2 on one side or on two opposite sides, which are arranged along the same sides parallel in sighting their height and in such a way inward they form vertical sliding connections $ .

On one of the other sides of this box

KSrpers 1 is a lower extension 4 formed, the one baltic seat for a drant-shaped bend leather 5 forms, one of which is Xbde 6 bent like a beak is. On the opposite side of the aforementioned "· lying side of the shell-like body 1 is a Stop 7 is provided, which is part of an annular Basic component 8 for the lower support of a compression spring 9 is,

The inside of the box-like body 1 is ax Possibility of axial displacement, a key 10 is used, is tubular and * it the box-like body 1 is prismatically coupled by elevations 11 and corresponding recesses 12

On one side or on two opposite sides This! Baste 10 are useful staggered helm seats 13 provided for Eontaktelemente, which consist of pins 14 against which a cylinder preferably from a cylinder Spring existing elastic member 15 acts.

On the outer wall of an intermediate or adjacent on the side of the button 10 lying on the side thereof, a return header section 16 is provided, which is an acquisition intermediate profile 17 that a lower peak 18 and an upper minimum point 19, which is indicated by lines inclined accordingly with respect to the longitudinal axis of the above-mentioned flexure spring 5 are formed

On the side opposite that, the

wearing the above-mentioned raised profile is a shiim iiO made of matt or transparent colored material hinged, which come into engagement with the stop 7 fixedly connected to the box-shaped body 1 can.

On the button 10 a cap or a cover Λ is attached, or which is provided with a transparent or translucent Mttelabschnitt 22, the 1Q carries a suitable imprinted symbol, which is used to specify the function or! Functions of the switch.

In these, the connection between two or more can be established reren solid lamellar contacts 3 through. bridges achieved; There are also several circuits for the power supply to control.

Within the box-like body 1, a light source is also arranged, which consists of both a lamp 23 as well as from the end section of a fiber optic cable 23 'can exist.

By pressing button 10 inside the box-like Body 1 can be the individual pin contacts 14 with the adjacent lemellenkontaktpaaren 2 and close the same sub-circuits.

The stability of the contacts is ensured by the beak-like end 6 of the wire-shaped flexion spring 5 snapping into the upper limit 19 of the raised area

Intermediate profiles 17 ensured so that a force counteracting the compression spring 9 is exerted. Another press on button 10, however, triggers the Qade of the same profile due to the special one Course s of the circumference 24, which delimits the recessed section 16., whereby the Button 10 is pressed by the compression spring 9 to the outside.

In any case, the beak-like bath holds the key 10 inside the box-like body 1 by being provided with a stop provided at the foot of the button 10 25 comes under attack.

When button 10 is pressed, i.e. with the switch closed, so that the direct illumination of the am transparent portion of the cap 21 imprinted concept mark takes place.

When the button 10 is raised, however, the ski 20 starts the bundle of light from the lamp or the light guide cable 23 ', which indicates the open state of the circuit will.

The screen 20 is advantageously made of transparent material or translucent and colored material, so that when the switch is open, the button 10 also closes in the I window sehdS is.
