Abstract

In an office machine, in particular in a matrix printer which is provided with a power grid component (3) for the power supply of the electrical or, respectively, the electronic circuits and which includes a safety fuse on the power grid input side, there is disclosed for purposes of more clarity of the construction, for an easier operability and for protection against false connection, that a multiple safety fuse socket (6) for at least two melting safety fuse bodies (9, 10) is coordinated to a voltage selection switch (7). The multiple safety fuse socket (6) can be placed in different relative geometric positions with respect to the voltage selection switch (7) into a fuse socket (8). A selected voltage is coordinated at the voltage selection switch (7) in each position of the multiple safety fuse socket (6).
