As already partially apparent from the above description of the figures, a modular system can be realized in a further embodiment to realize in the desired manner a socket without any lighting or a socket with orientation lighting or a socket with operating voltage display or a socket with orientation lighting / operating voltage display. The following components are part of such a modular system:

• a central disk 4 for orientation lighting (with light exit opening 7),
• a central disk 10 for operating voltage display (with light exit opening 11)
• a center plate for orientation lighting / operating voltage indication (with light emission openings 7 and 11),
• a central disc without any light emission opening,
• a device base for orientation lighting (which is also used for the embodiment orientation lighting / operating voltage display),
• a device base for operating voltage display (which is also used for the socket without any lighting at the same time),
• a lighting module 29 for orientation lighting,
• a lighting module 43 for operating voltage display,
• a lighting module for orientation lighting / operating voltage display,
• a cover frame 42.

Advantageously, the same light bulb 38 is used for all lighting modules.

As is apparent from the above description, the upper edge of the central disk 4 protrudes over the cover frame 42 with a defined dimension or projection, in order to allow the light exit surface 19 for the orientation illumination. To continue to comply with the normative dimensions of the socket, the socket insert must be raised relative to the support ring by the same amount. This projection is not required in the central disk 10, therefore, two different device base are required for the proposed modular system. However, one and the same socket insert is used.
