The invention relates to a system, for electrical installations, for very hard installation surfaces. In this arrangement, a base part is fastened on the installation surface and is then embedded flush in the plaster and is subsequently supplemented by an appropriate attachment part, corresponding to a functional element such as, for example, a switch or a plug, inter alia. In the case of very hard installation surfaces which are very difficult to machine, laborious machining such as is necessary for concealed installation is dispensed with; the surface-mounted installation which juts out to a large extent from the plaster is also avoided. The invention has advantages both for new installations and for development and renovation work. Technical details of the configuration and mounting of the system, for electrical installations, according to the invention are described in the subclaims.
