- FIG. 1 shows a cross section through a switch
- Fig. 2 is a partial sectional view of the switch of FIG. 1, cut in the
- 3 to 5 are top views of various embodiments of circuit boards
- FIG. 6 shows a detailed view according to FIG. 2 of a modified embodiment
- FIG. 7 shows a detailed view according to FIG. 2 of a modified embodiment
- Fig. 10 is a detail sectional view of a modified embodiment of a grinding area.
- a switch has a base plate 2 which is formed in one piece with housing walls 4 and itself forms the bottom of the housing of the switch.
- An actuating part 6 is displaceably guided on the housing walls 4.
- the displaceability can be such that the actuating part 6 can assume two defined positions (a retracted position and a rest position) or several defined positions or is merely designed as a button, it being possible to push it from a defined outer position into an inner position, from which it automatically returns to the outer position. Since not directly part of the invention, the guide of the actuating part and its possibly existing latching with the housing walls or the existing from the base plate 2 and the housing 4 existing part of the housing is not explained. Exemplary embodiments of such guides and latches are described in DE 31 45 803 C2.
- a circuit board 8 which extends approximately parallel to the direction of movement of the actuating part 6 and has the contact areas 10 at the points at which, in the different positions of the actuating part 6, grinding areas or contact sections of wire contact formed as a grinding bracket 12 - are 14 (Fig. 2).
- the circuit board 8 is advantageously an overall plate-shaped component which is inserted into recesses (not shown) in the actuating part 6 and is fastened therein, for example by means of gluing.
- the circuit board 8 can also be glued to web surfaces formed on the actuating part 6 or otherwise attached to the actuating part 6.
- each wire contact 14 is made by a wire bent in a predetermined manner, advantageously spring wire, such as berylium wire, which can be silver-plated or gold-plated.
- spring wire such as berylium wire
- the wire contact 14 is bent overall in an S-shape, so that an overall U-shaped bracket 16 and a free end 18 are formed.
- the U-shaped bracket 16 is inserted into a slot 20 of the base plate 2; the free end 18 protrudes through a hole 22 formed in the base plate 2.
- the wire contact 14 is received in a manner secure against rotation and securely by simply plugging it into the base plate 2, wherein, as shown in FIG. shaped bracket 16 indentations 24 can be formed, which bring about a latching with the base plate 2.
- the base plate 2 is designed directly as a printed circuit board with conductor tracks 26 which make electrical contact with the wire contacts 14.
- the electrically conductive material of the conductor tracks extends into the walls of the slot 20 and the hole 22, no soldering between the wire contact 14 and the base plate designed as a printed circuit board is required.
- the wire contacts can be fastened to the base plate in a different manner, for example by casting, connecting wires directly to the wire contacts can be soldered or crimped or otherwise attached to them.
- the base plate 2 is advantageously designed with webs 28 which limit the elastically preloaded pivoting of the wire contact 14 according to FIG. 2 in the counterclockwise direction, so that the circuit board 8 when it engages with the grinding bracket 12 from above comes, the outside or convex side is securely grasped and the grinding bracket 12 comes into elastic contact with the circuit board 8.
- the circuit board 8 in this exemplary embodiment consists of a plastic layer 30 facing the grinding bracket 12, which is formed with holes 32 in the region of the contact areas 10.
- a metallically conductive layer 34 is applied to the back of the plastic layer 30, which extends through the holes 32 and is exposed in the contact regions 10.
- the circuit board 8 can alternatively also be designed such that a metallic base plate is covered with a plastic mask which is perforated in the contact area 10. In this case, the contact areas 10 are deepened.
- the circuit board is advantageously made of Si-Cu and can also be silver-plated or gold-plated.
- the circuit board 8 can also be punched out of a metal plate (FIG. 5) and applied to a base plate advantageously made of plastic, so that predetermined contact areas are present and are electrically connected to one another in a predetermined manner.
- Fig. 3 shows an embodiment of a circuit board 8 with a metal plate, which is sealed upwards (towards the viewer) with a plastic layer, so that only the contact areas 10 are exposed at predetermined locations.
- the hatched areas are conductive areas that are in electrically conductive connection with each other.
- the circuit board 8 shown is used in a switch which has three wire contacts arranged next to one another, which correspond to the three regions of the circuit board according to FIG. 8 arranged next to one another.
- the two regions of each of the regions arranged one above the other correspond to two switching positions I and II.
- the left wire contact (not shown) a is connected to an electrically conductive contact region 10 both in position I and in position II.
- the middle wire contact b there is only one contact area 10 in position I.
- position II there is no electrical connection.
- a contact area 10 is only accessible in position II, whereas I no contact area is seen.
- the electrical equivalent image of the switch is shown on the right in Fig. 3 and corresponds to a changeover switch.
- Fig. 4 shows a circuit board 8, with the four wire contacts a, b, c and d not shown cooperate and which also has two switch positions I and II.
- the equivalent circuit diagram is shown on the right in FIG. 4.
- FIG. 5 shows an exemplary embodiment of a circuit board 8, which is formed by a stamped part and whose function corresponds to the circuit board according to FIG. 4.
- the contact areas 10 can be designed, for example, as depressions, so that there is a certain latching when the grinding brackets 12 reach the contact areas 10, which advantageously influences the feel of the switch.
- Fig. 6 illustrates these measures to achieve a high quality feeling of operation with the switch again.
- the circuit board 8 has in the area of the contact areas 10 regardless of whether these contact areas 10 are electrically conductive areas or not, recesses 32, into which the grinding bracket 12 of the wire contacts 14 move because of the elastic bias of the contacts 14, so that a certain "holding force" is created for the actuating part.
- the depressions 32 can also be formed at other locations at which certain actuation characteristics are desired, and that the depressions can be formed by grooves extending across the circuit board 8.
- Fig. 7 shows a modified embodiment of a circuit board 8 with contact areas 10 with an adapted embodiment of a wire contact 14.
- the circuit board 8 is continued down into a web 34 which has recesses 36 into which the projections 38 enter when the circuit board 8 together with the actuating part 6 (Fig. 2) is moved relative to the wire contact 14.
- the wire contact 14 is elastically biased to the left, so that the grinding bracket 12 is lifted off the projection 38 on the surface of the circuit board when the projection 38 is not in any recess 36. If the projection 38 comes into one of the recesses 36, the grinding bracket 12 comes into contact with the surface of the circuit board 8.
- This embodiment thus provides additional free space for the configuration of the circuit board 8 and allows a particularly effective influence on the actuation feel of the switch.
- circuit boards 8 can be formed on an actuating part 6, for example in a row one behind the other or on the four sides of a shaft projecting inwards from the actuating part, to which correspondingly numerous wire contacts 14 on the base plate 2 are assigned. In this way, an extremely complex switch with high miniaturization can be attached directly to a printed circuit board.
- the wire contact 14 has indentations 24 on the legs of the U-shaped bracket 16, which ensure a secure hold on the base plate 2.
- the metallic material of the Conductor tracks 26 advantageously extend along the end walls of the slot 20 and the wall of the hole 22, so that a secure electrical connection of the wire contact 14 to the conductor track 26 is ensured.
- Fig. 9 shows an example in which the grinding area of the wire contact 14 is not only formed by bending it to form a grinding bracket, but rather in that on the wire contact 14 a contact pan 40 made of suitable contact material, which can additionally be silver-plated or gold-plated, for example by soldering or welding.
- Fig. 10 shows another example in which the grinding area is formed in that a tube 42 made of suitable contact material is pushed onto the wire contact 14 and then pressed, the curved shape being achieved only in the pressing tool.
- the two embodiments according to FIGS. 9 and 10 have the advantage that the entire wire of the wire contact 14 does not have to be refined, for example by silvering or gold plating, and that the grinding area is very specifically matched to the circuit board in terms of material and shape for long operational reliability can be.
