As can be seen from the figures, such a contact carrier arrangement for electrical / electronic installation devices consists mainly of a housing 1, which has a housing upper part 2 and a housing lower part 3. In the upper housing part 2, several, each provided with two insulation displacement 4 cutting insulation displacement elements 5 are present. On the housing 1 four, cooperating with electrical lines 6 actuating lever 7 are pivotally mounted, which presses by manual depression the at least one associated electrical line 6 for contacting in one of the two insulation displacement regions 4 of the associated insulation displacement element 5. Each of the four operating levers 7 has two receiving openings 7h for the introduction of electrical lines 6. Thus, each operating lever 7 can be equipped with an electrical line 6 or two electrical lines 6 as needed. The four mounted on the housing 1 actuating lever 7 are combined in pairs to form a first lever assembly A and a second lever assembly B, wherein the two operating lever 7 of the first lever assembly A are pivotally mounted counter to the two operating levers 7 of the second lever assembly B on the housing 1. The four actuating lever 7 are assigned to the underside of the lower housing part 3 facing away from the upper housing part 2. Often, such electrical / electronic installation devices are provided with a carrier 8, which optionally spreader claws 9 are assigned to care for a common definition in conventional installation boxes. The carrier 8 is executed in the present case as a support ring and attached to the upper housing part 2.

As can further be seen from the figures, the two actuating levers 7 of the first lever arrangement A and the two actuating levers 7 of the second lever arrangement B are respectively three, formed by the upper housing part 2 and the lower housing part 3 first pivot bearing and, on the two associated actuating levers. 7 arranged second pivot bearing 7c rotatably mounted. The first pivot bearings are formed by bearing shells and interact with bearing lugs 7d of the associated operating lever 7 together. The first bearing shell halves 2b are on the upper housing part 2, and the second bearing shell halves 3b are provided on the lower housing part 3. The second pivot bearing 7c of the two lever assemblies A and B each consist of one, integrally formed on one of the two actuating lever 7 Bearing pin which engages in a molded-in in the other operating lever 7 bearing recess. Each of the four operating levers 7 has a storage area 7b and a lever area 7a. The lever portion 7a of each operating lever 7 is made approximately half as wide as the bearing portion 7b. Thus results in opposite operation of the respective two actuating lever 7 of the first lever assembly A and the second lever assembly B is a particularly compact design. Each actuating lever 7 is also provided on its bearing lugs 7d with a plurality of latching formations 7b, which cooperate with at least one, to the associated second bearing shell half 3b latching lug 3c. In addition, an actuating contour 7e is formed in each actuating lever 7, so that if necessary it is possible to actuate the actuating lever 7 by means of a tool. In the illustrated embodiment, however, an actuation by means of a tool is not provided, which is why the lower housing part 3 completely obscures the engagement in the actuating contour 7e. In addition to the possible lateral actuation by means of tools, there is also the further possibility of grasping the lever end with the tool and thus releasing the actuation lever 7. In addition, in each of the four actuation levers 7, as already mentioned, two exception openings 7h are provided for introducing in each case one electrical line 6. In addition, each operating lever 7 is integrally provided with a, to be introduced with the electrical line 6 and with the two introduced electrical leads 6 cooperating stop element 7b to provide a defined stop for the insertion available, then subsequently for a secure contact of the electrical Lines 6 with the associated insulation displacement elements 5 care is taken. In order to permanently secure the upper housing part 2 to the lower housing part 3, first clip elements 2a and second clip elements 3a, which come into operative connection with one another, are integrally formed thereon. The first clip elements 2a, which are formed on the upper housing part 2, are designed as clip hooks and the second clip elements 3a, which are formed on the lower housing part 3, are designed as clip tabs. The lower housing part 3 has, on its underside facing away from the upper housing part 2, two receiving spaces 14 for accommodating the four actuating levers 7. If the actuating levers 7 are in their closed position by manual depression, they submerge into the receiving spaces 14 almost completely, so that a particularly compact design is realized.

Such a compact design is particularly suitable if an installation of the electrical / electronic installation devices is provided in conventional installation boxes. As already described, the manual transmission of the actuating lever 7, the associated electrical leads 6 are pressed into the associated insulation displacement region 4 of the associated insulation displacement element 5. As in particular from FIG. 5 As can be seen, each insulation displacement element 5 has two separate insulation displacement regions 4, which can receive or contact two different cross-sections. When the actuating lever 7 is equipped with two electrical lines 6, each of the two electrical lines 6 is thus pressed into a separate insulation displacement area 4 of the associated cutting element 5. Thus, a secure electrical connection between the electrical line 6 and the two electrical lines 6 and the associated insulation displacement element 5 is produced in a simple manner.

As in particular from FIG. 1 and FIG. 3 shows, the electrical / electronic installation device is designed as an electrical switch. On the upper housing part 2, a contact piece 10 is pivotally mounted, which is provided on the upper side for assembly with at least one - for simplicity not shown-Betätigungsestaste and which cooperates on the underside via a pressure piece with at least one, pivotally mounted in the housing 1 switching contact part 11. In the present embodiment, two switching contact parts 11 are provided, which are each designed like a rocker. For protected placement of the two switching contact parts 11 and the four insulation displacement elements 5, a protective cover 13 is fixedly mounted in the interior of the housing 1. The upper housing part 2 has four receiving chambers 2c, which are each provided for positionally correct receiving one of the four insulation displacement elements 5. Two of the four insulation displacement elements 5 have a cutting edge bearing 5a and two of the four insulation displacement elements 5 have a mating contact 5b to cooperate with one of the two associated switching contact parts 11, so that the desired switching functions can be performed.

As in particular from FIG. 5 emerges and as already described above, two of the four insulation displacement elements 5 a blade bearing 5a and have two of the four insulation displacement elements 5 on a mating contact 5b. About the cutting edge bearing 5a, the rocker-like switching contact part 11 is pivotally mounted on the associated insulation displacement element 5 on the one hand. On the other hand, the switching contact part 11 cooperates with a mating contact 5b of a further associated insulation displacement element 5. In each case an insulation displacement element 5 with cutting edge bearing 5a, an insulation displacement element 5 with mating contact 5b and a switching contact part 11 each form one of two contact arrangements. Via a gooseneck-like extension, the cutting edge bearing 5a is in one piece with the base 5c of an insulation displacement element 5 in combination. The mating contact 5b is designed as an angled approach and also integrally formed on the base 5c of an insulation displacement element 5. Starting from the base 5c, three legs are also bent away from this in order to be able to provide two insulation displacement regions 4 via one insulation displacement element 5 each. A fixed first leg 5d is associated with two resilient second legs 5f. The two second legs 5f are each associated with their arcuately running cutting edge of one of the two cutting edges of the first leg 5d. The two edges of the first leg 5d are also arcuate.

In a simple manner, a contact carrier arrangement for electrical / electronic installation devices is realized, which has a particularly compact construction with cost-effective production. It is particularly advantageous that is present by the arrangement of all operating lever 7 on the underside of the lower housing part 3, a special suitability of the contact carrier assembly for electrical / electronic installation equipment, which are provided for installation in conventional installation boxes.
