The lower base part 2 has, on its underside facing away from the upper base part 1, a receiving space A for accommodating the three actuating levers 12, 14. Are the operating lever 12, 14 by manual depression - starting from the in FIG. 4 shown open position - in their closed position, these closely nested immerse almost completely in the receiving space A, so that even by this measure a particularly compact design is realized. Such a compact design is particularly suitable if an installation of the electrical / electronic installation devices (safety socket) is provided in standard installation boxes. As already described, the manual operation of the actuating levers 12, 14, the associated electrical leads L are pressed into the associated insulation displacement region 5a of the associated insulation displacement element 5. Each insulation displacement element 5 has two separate insulation displacement areas 5a, which can receive or contact two different cross sections. If the actuating levers 12, 14 are equipped with two electrical leads L, then each of the two electrical leads L is pressed into a separate insulation displacement region 5a of the associated insulation displacement element 5. Thus, a secure electrical connection between the electrical line L or the two electrical lines L and the associated insulation displacement element 5 in a simple manner.

As in particular from FIG. 1 and FIG. 5 shows, each of the three insulation displacement elements 5 has a base, are bent starting from the three legs. This serves the purpose so that each insulation displacement element 5 can provide two insulation displacement regions 5a in a simple manner. A fixed first leg is associated with two resilient second leg. The two second legs are assigned in each case with their arcuately running cutting edge of one of the two cutting edges of the first leg. The two cutting edges of the first leg are also arcuate.

In a simple manner, a contact carrier assembly for electrical / electronic installation devices (safety sockets) is realized, which has a particularly compact construction with cost-effective production. It is particularly advantageous that is given by the arrangement of all operating levers 12, 14 on the underside of the base part 2 a special suitability of the contact carrier assembly for electrical / electronic installation equipment, which are provided for installation in conventional installation boxes.
