Abstract
A device for change-over switching of electric motors has a housing and two safety disconnecting switch systems positioned adjacently to one another in the housing. A cover is slidably connected to the housing so as to cover one of the safety disconnecting switch systems respectively. A fuse holder with fuses is detachably connected to the housing. Each one of the safety disconnecting switch systems has receiving elements for receiving the fuses. The safety disconnecting switch systems are electrically connected to one another such that upon insertion of the fuses into the receiving elements of one of safety disconnecting switch systems the electric motors rotate in one rotational direction and that upon insertion of the fuses into the receiving elements of the other one of the safety disconnecting switch systems the electric motors rotate in the other rotational direction. The fuse holder is detachably connected to the housing adjacent to the cover such that the cover covers one of the safety disconnecting switch systems and that the fuses are inserted into the other one of the safety disconnecting switch systems.
