Abstract: The invention relates to a method for producing fibre-reinforced hollow bodies comprising integrally formed elements in a hollow mould. A fibre mat is laminated in two halves of the hollow mould, which respectively form the negative mould for the fibre-reinforced hollow bodies comprising integrally formed elements to be produced, and, once the two halves of the thus lined hollow mould have been connected, the fibre mat is pressed into the hollow mould under pressure in a form-fitting manner. The invention also relates to products produced according to the inventive method.

Each pluggable electrical unit has module electronics and a read-only memory with clearly identifying identifiers. The interface is equipped with a variable resistor in a feed line. The connection between the base unit and the pluggable electrical unit is established initially only partially, and only to the read-only memory, after switching on the power supply to the pluggable electrical unit.

The covering (24) can only be brought into the rest position in the locked state of the pluggable electrical unit (2).
