Description

Description [0001] The present invention relates to an electrome-chanical relay according tothe preambleofclaim 1. More particularly, the present invention relates to an electro-mechanical relay thatfits into electrical devices with lim-ited space or special shapes.

[0002] US 2003/174038 discloses a relay 7 comprising afirst non-flexible substrate 16 and asecond flexible sub-strate 40, see figure 1 below. There is provided a con-ductive member 17 on top of the first substrate 16 and the conductive member 50 on top of the second flexible substrate 40. Further, there is provided a coil 22 in coil support structure 11 attached to the second substrate 16. Opposite the coil 22, on top of the flexible substrate 40, there is provided a ferritic member 48. The description explains that although only two coils are shown, the array may have a 10x10 array or larger to provide a multitude of independent or dependent relay circuits as desired.

[0003] A known electromechanical relay typically com-prises a coil that is mounted on a base made of, for ex-ample, ¡ron (yoke), an armature of magnetic material which is movable with respect to the base, and a first contact element made out of electrically conductive material and connected to the armature. The first contact element is intended to establish ordisconnect electrical contact with a second contact element, depending on whether the coil has been charged or not. By sending a currentthrough the coil, a magneticfield is generated for moving the armature in such a way that the electrical contact between the first contact element and the second contact element is established or disconnected. Such a relay has as a disadvantage that it is not very compact, and, therefore, difficult to intégrate into small electrical devices of which the space within the device is limited and/or of which the shape is fixed.

[0004] The aim of the present invention is to provide an electromechanical relay, the shape of which can be adapted to any desired shape of electrical device. In particular a relay is provided that, together with other elec-tronic components, can fit into any kind of electrical device shape with a limited volume, and, more in particular, a compact relay that can form a relatively thin, fíat unit.

[0005] For this purpose, an electromechanical relay according to the invention has the features of claim 1. The electromechanical relay comprises a carrier, a contact body which is connected to the carrier and which is movably mounted with respect to the carrier, at least one electrical contact element, and at least two coils to move the contact body with respect to the carrier, in order to disconnector establish an electrical contact between the contact body and the at least one electrical contact element. The contact body is adapted to be moved as a result of a magnetic field generated by the at least two coils. The at least two coils are provided on or in the carrier and/oron or in the contact body. The carrier and/or the contact body are made out of electrically insulating material, on or in which electrically conductive tracks are provided. The carrier and/or the contact body are further adapted for mounting electronic components thereon, which electronic components are connectable to the electrically conductive tracks.

[0006] Embodiments of the invention are ínter alia based on the inventive insight to combine a plurality of coils with a relatively small height next to each other between a carrier and a contact body, and to give an addi-tional function to the carrier and/or contact body, namely forming a mounting surface for electronic components, like resistors, capacitors, chips, etc. In this way, a relay can be obtained with any desired shape, and, in particular, a relatively thin and compact relay can be provided that is easy to intégrate in an electronic Circuit.

[0007] According to embodiments of the invention, the contact body is connected to the carrier and is, therefore, notfloating.

[0008] A plurality of coils is located next to each other in a plañe parallel to the carrier and/or the contact body. The axes of the coils may preferably be substantially perpendicular to the carrier and/or the contact body. The coils can be mounted onto the carrier and/or onto the contact body, whereby, for example, also at least a first coil can be mounted onto the carrier and at least a second coil onto the contact body.

[0009] The carrier and/or the contact body may preferably be implemented as a printed Circuit board (PCB). The contact body and/or the carrier are preferably plate-shaped and may preferably be thin plates so that a thin assembly can be obtained. These plates can have any shape depending on the design of the electronic device in which the relay is required. Furthermore, the shape of the carrier can be difFerent from or equal to the shape of the contact body. The carrier may preferably have a thick-ness of less than 3 mm. The contact body may preferably have a thickness of less than 3 mm.

[0010] According to a possible embodiment, the contact body may entirely be made out of a magnetic material, for example an ¡ron alloy. According to another embodiment, the contact body may have zones of magnetic material, which are provided in such a way that they can cooperate with the coils, to guide the magnetic flux. According to still further embodiments, for example, one or more permanent magnets may be provided onto or in the contact body.

[0011] According to an advantageous embodiment, at least one spring means may be provided between the carrier and the contact body. The or each spring means may preferably have a first end that is fixed to the carrier and a second end that is fixed to the contact body. Using more than one coil and a spring-mounted assembly of the contact body allows the height of the relay to be limited and/or any desired height to be obtained. The contact body may, according to embodiments of the invention, also in another way resilient, hingedly orotherwise movably be hung up or mounted with respect to the carrier.

[0012] According to embodiments of the invention, the or each spring may be adapted to form an electrically conductive path between the carrier and the contact body.

[0013] According to a possible embodiment, the carrier may have a first side on which the at least two coils and the contact body are provided and a second side, oppo-siteto the first side, on which an invention, also in another way resilient, hingedly orotherwise movably be hung up or mounted with respect to the carrier.

[0014] According to embodiments of the invention, the or each spring may be adapted to form an electrically conductive path between the carrier and the contact body.

[0015] According to a possible embodiment, the carrier may have a first side on which the at least two coils and the contact body are provided and a second side, oppo-site to the first side, on which an electronic component is provided. Further, one or more electronic components can also be provided on this first side. Furthermore, one or more electronic components can be provided on one side of the contact body or on both sides thereof.

[0016] The at least one contact element is provided directly to the carrier on a side facing the contact body. In other embodiments, not claimed in this application, it can also be provided at a different location, for example at a distance from the carrier, on the other side of the contact body. The at least one contact element is provided between two adjacent coils on the carrier.

[0017] According to advantageous embodiments of the invention, at least four coils may be provided, which are placed next to each other in a plañe between the carrier and the contact body. This will allow the distance between the carrier and the contact body to be kept rel-atively small, while the coils can exert a sufficiently large forcé on the contact body without very high currents being required. The distance between the carrier and the contact body, in the condition in which the at least one contact element does not make contact with the contact body, may preferably be less than 1.5 times the diameter (1,5*d) of a coil, more preferably smaller than the diameter of the coil, and most preferably less than 0.75 times the diameter (0.75*d) of the coil. This distance may preferably be less than 10 mm, or more preferably less than 5 mm.

[0018] The at least one electrical contact element may, for example, comprise a spring contact or a spherical contact. Moregenerally, the at least one electrical contact element can have any shape. Furthermore, contact ele-ments of different types can be combined in one relay.

[0019] According to an advantageous embodiment, the carrier and/or the contact body may be a PCB, and each coil may be formed with conductive tracks of the PCB (PCB track coil). Hereby the conductive tracks may, according to embodiments of the invention, be provided in múltiple layers of the PCB. In this way, the compact-ness of the relay can be further enhanced.

[0020] According to an embodiment invention, each coil may be provided with a core of magnetic material. Further, each coil can also be surrounded by at least one element of magnetic material in order to, together with the at least one coil and the contact body, form a magnetic Circuit. Such an element can be mounted againstthe contact body or against the carrier. Furthermore, such an element can be resilient or spring-mounted. When the contact body, as a result of charging the at least one coil, moves in the direction of the carrier, such a spring element of magnetic material can then be pushed in.

[0021] The relay may comprise an additional movably mounted contact body, an additional carrier, and at least two additional coils to generate a magnetic field for mov-ing the additional contact body with respect to the additional carrier. The contact body and the additional contact body are hereby facing each other and are located between the carrier and the additional carrier. The additional carrier may be located at a fixed distance from the carrier, and the at least one contact element may be provided on or may be formed by the additional contact body. In this way, the relay function is thus built in between two carriers, wherein two sets of coils located above each other are present between the carriers, and wherein additional electronic components can be mounted onto the carriers. The carriers may preferably be PCBs.

[0022] The relay may comprise an additional carrier at a fixed distance from the carrier. The additional carrier is provided with at least one contact element at a side facing a side of the contact body. Between the contact body and the carrier, there may be a movable intermedíate body, typically a separator píate, on which or in which at least two additional coils are provided for the generation of a magnetic field to move the contact body with respect to the intermedíate body. In this way, the distance between the contact body and the at least one contact element (in the open position) can be increased. Also two sets of coils, which contribute to the movement of the contact body with respect to the carrier, are provided above each other. Furthermore, other electronic components can be provided on both the carrier and the additional carrier.

[0023] According to a possible embodiment, the at least one contact element may comprise at least a first contact element on a first side of the contact body and at least a second contact element on a second side of the contact body, and the contact body may be mounted and designed so as to make electrical contact with the first contact element in a first position and with the second contact element in a second position. In this way, a two-way Circuit can be formed, in which the contact body al-ternately makes contact with the first contact element and the second contact element.

[0024] According to a possible embodiment, the contact body may be movable between a first and a second position as a result of the generation of respectively a first and a second magnetic field by means of the at least two coils. This is called a bi-stable relay. To obtain a bi-stable relay, at least one permanent magnet may be provided onto the carrier and/or the contact body in such a way that the contact body is kept in the first position after removal ofthefirst magneticfield and/orthatthe contact body is kept in the second position after removal of the second magneticfield. According to embodimentsofthe invention, the contact body may be spring-mounted with respect to the carrier by means of at least one bi-stable spring element, whereby the at least one bi-stable spring element is mounted in such a way that the contact body is kept in the first position after removal of the first mag-netic field and/or that the contact body is kept in the second position after removal ofthe second magneticfield.

[0025] According to a further developed embodiment, the at least one contact element may comprise a first contact element and a second contact element, and the at least two coils are provided in such a way that, as a result of selectively charging one or more of these coils, the first and second contact element can selectively make contact with the contact body. Inthisway, compact múltiple relays can be built.

[0026] The present invention will be further explained on the basisof a numberof, by no means limiting, exem-plary embodiments of an electromechanical relay according to the invention, with reference to the attached drawings.

[0027] A first embodiment of an electromechanical relay according to the invention is shown in figures 1A-1C. The relay comprises a carrier 4 onto which a number of coils 1 are mounted. According the present embodiment,

the carrier 4 may be implemented in the form of a PCB 4. The coils 1 are positioned next to each other onto the PCB 4 and in a plañe parallel to the PCB 4. In the illus-trated example, sixteen coils 1 have been provided. It has to be understood by a person skilled in the art that this number is not meantto be limiting in any way, a relay according to embodiments ofthe invention can have any numberof coils 1 asrequiredfortherelevantapplication. A contact body 3 is movably mounted with respect to PCB 4 by means a numberof springs 5. According to the present embodiment, the contact body 3 may be provided in the form of a contact píate 3 made out of a magnetic material, for example an ¡ron alloy. According to further embodiments ofthe invention which have not been illus-trated, the contact body 3 may be a PCB on which or in which one or more permanent magnets are provided. Each of the at least one coil (1) may have an axis that is oriented perpendicular to the carrier (4) and/or the contact body (3). In the illustrated example, four springs 5 are provided in between PCB 4 and contact píate 3 at the corners ofthe PCB 4 and the contact píate 3. A person skilled in the art will understand that, according to embodiments ofthe invention, moreor lessthanfoursprings 5 may be provided, and that the springs 5 can be provided at other positions than in the corners. These springs 5 may, according to some embodiments ofthe invention, also have an additional function, for example the function of an electrical conduction between the contact píate 3 and a conductive path on PCB 4 which is connected to an electronic component 6 that is mounted on PCB 4. In order to keep the distance between contact píate 3 and PCB 4 small, the ends of the springs 5 may preferably be attached directly to contact píate 3 at the one end and to PCB 4 at the other end.

[0028] The relay furthermore comprises a number of electrical contact elements, here in the form of a pillar-shaped electrically conductive element 2a and four elec-trically conductive spring elements 2b. These contact elements 2a, 2b are intended to make contact with the contact píate 3 in the closed position ofthe relay. Provid-ing a current through the coils 1 allows for a movement of the contact píate 3 in the direction of the carrier 4, in order to establlsh an electrical contact between contact píate 3 and contact elements 2a, 2b. According to embodiments ofthe invention that have not been illustrated, it is also posslble that the relay is originally closed (i.e. that an electrical contact is present between contact píate 3 and contact elements 2a, 2b) and that charging the coils 1 causes the movement ofthe contact píate 3 away from the carrier 4 in such away that the electrical contact is disconnected.

[0029] In the present embodiment, the coils 1 are provided on a fíat top surface of PCB 4, but, according to alternative embodiments, the coils 1 may also be provided in cavities in the PCB 4 or as conductive tracks of PCB 4 in the shape of so-called PCB track coils.

[0030] In the embodiment illustrated in figures 1A-1C, the coils 1 and the contact píate 3 are provided on a top side 41 of PCB 4, and the bottom side 42 of PCB 4 is intended for mounting additional electronic components 6. However, it is also possible to provide additional electronic components 6 at the top side 41 of PCB 4 or at the top or bottom of contact píate 3, see also the embodiment of figure 4 which is discussed below.

[0031] The distance D (see figure 1B) between PCB 4 and contact píate 3 may preferably be relatively small, for example less than 5 mm in the condition in which the contact elements 2a, 2b do not make contact with the contact píate 3, in such a way that a thin compact unit is obtained. The distance D between PCB 4 and contact píate 3 may preferably be less than 1.5 times the diameter d (1,5*d) of the coil 1, more preferably smaller than the diameter d of the coil 1, and most preferably less than 0.75 times the diameter d (0.75*d) of the coil 1.

[0032] According to embodiments of the invention, the coils 1 can be provided with a core of magnetic material. Further, the coils 1 can be surrounded by at least one element of magnetic material to cióse the magnetic Circuit. In the example of figures 1A-1C, each coil 1 may be surrounded by four beam-shaped elements 8 of magnetic material. Further, instead of four beam-shaped elements 8, according to embodiments of the invention, also one tubular element 8 can be provided around a coil 1 (see also figure 4), and these elements 8 could also be at-tached to the contact píate 3 instead of to PCB 4.

[0033] The relay illustrated in figures 1A-C is a so-called monostable relay, i.e. a relay of which the contact body 3 during charging of the coils 1 is kept in a first position (here a closed position) and springs back to a second position (here the open position) at the time that the charge is removed. It is, however, also possible to build the relay of figures 1A-C as a so-called bi-stable relay, i.e. a relay ofwhich the coils 1 can move the contact body 3 from a first position to a second position and vice versa (for example, by reversing the direction of the cur-rent sent through the coils 1), and ofwhich the contact body 3 after the removal of the charge stays in the rele-vant position. For this purpose, one or more springs 5 can be implemented as so-called bi-stable spring elements, i.e. spring elements that after spring rebound or compression remain in the rebound or compressed position, respectively. An example of such a spring element 5 is a leaf spring, which shows a buckling phenomenon during the spring rebound and compression. According to embodimentsofthe present invention, such a bi-stable spring element can easily be provided in the contact body 3, as is illustrated in figures 8A and 8B. The bi-stable spring elements 15 are formed by cutting out zones of the contact píate 3 and by creating a permanent bending deformation vía a narrow bridge zone. According to typ-ical embodiments, the contact píate 3 may be sufficiently thin and/or elastic so that the bending deformed zone will, when a point forcé is applied, jump to the other side of the contact píate 3. Figures 8A and 8B ¡Ilústrate one bi-stable spring element 15, but a person skilled in the art will understand thatseveral such spring elements 15 can be installed. Figures 9A and 9B ¡Ilústrate the opera-tion of such a bi-stable spring element 15. Figure 9A ¡I-lustrates the open position. When the contact píate 3 is attracted as a result of a magnetic field generated by the coil 1, the bi-stable spring element 15 is pressed against the carrier4, and it willjump to its reversed fixed position, see figure 9B. The bi-stable spring element 15 will hereby make contact with an opposite stop 16, such that the contact píate 3 is pushed against the contact elements 2a. The contact píate 3 will remain in this position until again a magnetic field is generated that ensures that the contact píate 3 is moved up, away from the contact elements 2a. At that time, the bi-stable spring element 15 returns to the position of figure 9A. According to a further embodiment that is not illustrated, the bi-stable spring elements 15 can also be provided on the carrier4.

[0034] According to embodiments ofthe invention, one or more permanent magnets (not shown in figures 1A-C) can be provided on the carrier4. To allow movement ofthe contact body 3 from the closed position to the open position, the coils 1 are charged in such a way that the magnetic forcé that is generated can overeóme the magnetic forcé of the permanent magnets in order to move the contact body 3 from the closed position to the open position. This may, for example, be achieved by sending a sufficiently high current in the reverse direction (in com-parison with the direction needed to move the contact body 3 from the open to the closed position) through the coils 1.

[0035] Although in the description above, it was de-scribed to charge the coils 1 simultaneously so as to move the contact body 3 from a closed position to an open position and vice versa, a person skilled in the art will understand that it is also possible to charge the coils not simultaneously, so that the contact body 3 is, for example, tilted, and not allcontacts are closed. The contact elements 2a, 2b do not have to be electrically connected to each other, and the sepárate control ofthe coils 1 will then allow the selective contact ofthe contact elements 2a, 2b with the contact body 3 so that múltiple independ-ent switching electrical circuits can be realized. This will make multi-switch actions possible, and it will, for example, be possible to obtain an electrical two-way Circuit.

[0036] Figure 2 illustrates a second embodiment of a relay. Similar parís have been indicated with the same reference numbers as in figure 1. The relay comprises, similar to the relay illustrated in figure 1, a contact body in the form of a contact píate 3, a carrier in the form of a PCB 4 and at least one coil 1, in the example given a plurality of coils 1, provided on the PCB 4. According to the second embodiment, an additional movably mounted contact píate 3’, an additional carrier in the form of PCB 4’ and at a fixed distance from PCB 4, and a number of additional coils T for the generation of a magnetic field to move the additional contact píate 3’ with respect to additional PCB 4’, are provided. The additional coils T are provided on the additional PCB 4’. Contact píate 3 and additional contact píate 3’ are facing each other and are located between PCB 4 and PCB 4’. The at leastone electrical contact element isformed here as a numberof contact paths 2c which are provided on the additional contact píate 3’ on a side facing the contact píate 3. Ac-cording to the present embodiment, both coils 1 and additional coils T will contribute to the movement toward each other of contact píate 3 and additional contact píate 3’. In this way, the distance between the contact body 3 and the contact elements 2 can be increased. Further-more, both the top side of PCB 4’ and the bottom side of PCB 4 are available for mounting electronic components 6 thereon.

[0037] The relay illustrated in figure 2 is a monostable relay. It is, however, also possible to build the variant of figure 2 as a so-called bi-stable relay. For this purpose, one or more springs 5 can be implemented as so-called bi-stable spring elements, as described for the embodiment of figure 1 and as illustrated in figures 8A, 8B, 9A and 9B.

[0038] Also for the variant of figure 2, the coils 1 and T can be charged simultaneously or separately, or group by group (for example, four at a time), depending on whether it is desirable to obtain a single or a composed múltiple relay.

[0039] Figure 3 illustrates a third embodiment of a relay. Similar parts have been indicated with the same ref-erence numbers as in figure 1. The relay comprises, similar to the relay illustrated in figure 1, a contact body in the form of a contact píate 3, a carrier in the form of a PCB 4 and at least one coil 1, in the example given a plurality of coils 1. According to the third embodiment, an additional PCB 4’ is provided at a fixed distance from PCB 4. The contact píate 3 is provided in between the PCB 4 and the additional PCB 4 and at least one contact element 2d is provided on the additional PCB 4’ on a side facing a side of the contact píate 3. Between the contact píate 3 and PCB 4, a movably mounted intermedíate píate 7, for example a PCB 7, is provided onto which a plurality of coils 1" are mounted for the generation of a magnetic field to move contact píate 3 with respect to the intermedíate píate 7. In this way, both coils 1 and 1" will contribute to the movement of contact píate 3 in the direction of the electrical contact elements 2d. Furthermore, both the top side of PCB 4’ and the bottom side of PCB 4 are available for mounting electronic components 6 thereon.

[0040] The relay illustrated in figure 3 is a monostable relay. It is, however, also possible to build the variant of figure 3 as a so-called bi-stable relay. For this purpose, one or more springs 5a, 5b can be implemented as so-called bi-stable spring elements, as described for the embodiment of figure 1. According to embodiments of the invention, permanent magnets can further be mounted on the bottom side of PCB 4’, see also the embodiment of figure 6.

[0041] Also for the variant of figure 3, the coils 1 and 1" can be charged simultaneously or separately, or group by group (for example, two orfour at a time), depending on whether it is desirable to obtain a single ora composed múltiple relay.

[0042] Figure 4 illustrates a fourth embodiment of a relay according to the invention. Similar parts have been indicated with the same reference numbers as in figure 1. According to the fourth embodiment, the contact body is formed by a frame-shaped PCB 3. At the bottom side of PCB 3, a numberofzones 18of magnetic material are provided, which zones 18 extend above the coils 1 which are provided on the carrier 4. Furthermore, PCB 3 is provided with additional contact elements 13 formed of elec-trically conductive material, which are intended to make contact with electrical contact elements 2b, here implemented as spring contacts, on PCB 4. According to the fourth embodiment, the coils 1 are provided on PCB 4 at a distance from each other, and additional electrical components 6, 6", 6"" are provided on the top side and/or bottom side of PCB 4. Furthermore, the opening in frame-shaped PCB 3 allows a high electronic component 6" to be provided on PCB 4, as this component 6" can stick outthrough the opening. Furthermore, electrical components 6’, 6"’ can for example also be provided on the bottom and the top of PCB 3.

[0043] The monostable relay illustrated in figure 4 can also be built as a so-called bi-stable relay, as described in the embodiment of figure 1.

[0044] Also for the variant of figure 4, the coils 1 can be charged simultaneously or separately, or in groups, depending on whether it is desirable to obtain a single or a composed múltiple relay. The two coils 1 on the left can, for example, be charged simultaneously in order to realize a contact between contact elements 2b, 13 on the left, and the two coils 1 on the right can be charged simultaneously in order to realize a contact between contact elements 2b, 13 on the right, wherein the coils 1 on the left and the coils 1 on the right can be charged inde-pendently from each other.

[0045] Figure 5 illustrates a fifth embodiment of a relay according to the invention. Similar parts have been indicated with the same reference numbers as in figure 1. According to the fifth embodiment, the coils 1 are rela-tively high and slim compared to the rather fíat coils of the embodiments illustrated in figures 1 to 4. The springs 5 are here implemented as windings around the coils 1. In this way, a space is created between PCB 3 and PCB 4, where relatively high electronic components 6 can be provided. The contact elements are not illustrated, but may, for example, be similar to those of figures 1A-C or those of figure 4.

[0046] Figure 6 illustrates a sixth embodiment of a relay according to the invention. Similar parts have been indicated with the same reference numbers as in figure 1. According to the sixth embodiment, an additional PCB 4’ is provided at a fixed distance of PCB 4. The at least one electrical contact element is here implemented as a number of contact paths 2a, 2d, which are provided on the top side 41 of PCB 4 and at the bottom side of additional PCB 4’, respectively. These contact paths 2a, 2d are intended to cooperate with corresponding contact paths 13a, 13d at respectively the bottom and topof con-tact body 3. Both the top of PCB 4’ and the bottom of PCB 4 are available for mounting electronic components 6 thereon.

[0047] The relay furthermore comprisessprings 5. Ac-cording to a first possibility, the springs 5 may be such that the contact paths 13d in a first position of rest make contad with contact paths 2d. By charging coils 1, contact píate 3 can be moved to a second position in which the contact paths 13a make contact with the contact paths 2a. In this way, a two-way Circuit can be realized.

[0048] According to a second possibility, which is illus-trated in figure 6, the springs 5 are such that the contact paths 13d in an intermediary position do not make contact with contact paths 2d and that the contact paths 13a do not make contact with the contact paths 2a. By charging the coils 1 in respectively a first direction and a second direction opposite to the first direction, the contact píate 3 can be moved to a first position in which the contact paths 13d make contact with the contact paths 2d, and to a second position in which the contact paths 13a make contact with the contact paths 2a. Further, permanent magnets 9 may be provided at the bottom of additional PCB 4’ and/or at the top of PCB 4 in order to keep the contact píate 3 in the first or second position in case of removal of the charge.

[0049] Figure 7 illustrates a seventh embodiment of a relay according to the invention. Similar parís have been indicated with the same reference numbers as in figure 1. The relay according to the seventh embodiment com-prises: an additional PCB 4’ at a fixed distance from PCB 4; an additional contact píate 3’ spring-mounted with respect to PCB 4’ by means of springs 5’, atthe bottom thereof; and additional coils T for moving contact píate 3’ with respect to PCB 4’.

The contact píate 3 and additional contact píate 3’ are provided in betweenthePCB4and PCB 4’and arefacing each other. The at least one electrical contact element is here implemented as a number of contact paths 2a, 2a’, which are provided on the top side 41 of PCB 4 and at the bottom side of additional PCB 4’. These contact paths 2a, 2a’ are intended to cooperate with correspond-ing contact paths 13a, 13a’ at the bottom of contact píate 3 and the top of contact píate 3’, respectively. Further, the bottom side of contact píate 3’ and the top side of contact píate 3 are provided with contact paths 13b’, 13b respectively. Both the top side of PCB 4’ and the bottom side of PCB 4 are available for mounting electronic components 6 thereon.

[0050] The springs 5, 5’ may be such that the contact paths 13b in an intermediary position do not make contact with contact paths 13b’ and that the contact paths 13a, 13a’ do not make contact with the contact paths 2a, 2a’ (situation illustrated in figure 7). By charging the coils 1 in a first direction and a second direction opposite to the first direction, respectively, the contact píate 3 can be moved to a first position in which the contact paths 13a make contact with the contact paths 2a, and to a second position in which the contact paths 13b make contact with the contact paths 13b’. By charging the coils 1’ in a first and a second opposite direction, respectively, the contact píate 3’ can be moved to a first position in which the contact paths 13a’ make contact with the contact paths 2a’, and to a second position in which the contact paths 13b make contact with the contact paths 13b’. Further, the coils 1,1’ can be charged simultaneously or separately. A person skilled in the art will understand that in this way a plurality of switch combinations can be realized with a very compact relay.

[0051] Similar as in the embodimentdescribed with respect to, for example, figures 3 and 4, both the top of PCB 4’ and the bottom of PCB 4 are available for mounting electronic components 6 thereon.

[0052] If in the embodiment illustrated in figure 7 the coils 1,1’ are charged alternately in order to selectively cióse or open certain contacts, the contact plates 3, 3’ will in certain situations take a tilted position. In order to realize a proper contact in such a position as well, the contact elements 2a, 2a’, 13a, 13a’, 13b, 13b’ can, for example, havearoundedshape.asschematicallyshown in figure 7.

[0053] The above-described electrical contact elements 2a, 2a’, 2b, 2c, 2d, can, by means of conductive tracks on the PCB 4, be connected to a Circuit in which the relay function should be provided. Similarly, contact píate 3 (first, second, third and fifth embodiment) or contact elements 13, 13a, 13a’, 13b, 13b’ (fourth, sixth and seventh embodiment) can, by means of a conductive wire or track, be connected to the Circuit in which the relay function is required. This Circuit can partially orfully be provided onto a carrier/PCB 4, 4’ or a contact body/PCB 3.

[0054] In the illustrated embodiments, the coils 1 are always mounted to or in a fixed carrier in the shape of PCB 4 or additional carrier in the shape of PCB 4’. How-ever, it is also possible to mount the coils 1 onto or in the contact body 3 or additional contact body 3’ and to install the necessary magnetic zones 18 on or in PCB 4 or PCB 4’.

[0055] A person skilled in the art will understand that different embodiments can be combined with each other. For example, the frame-shaped contact píate of figure 4 can also be used in the embodiments of figures 1A-C, 2, 3, 5, 6, 7, where the contact elements should of course be provided in locations that have been adapted to the electrically conductive zone(s) of the contact body/PCB 3.

[0056] A person skilled in the art will understand that many modifications and additions are possible within the framework of the present invention, which in no way is limited by the exemplary embodiments described above. The scope of protection is only determined by the follow- ing claims.
