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.

Device for change-over switching of individual electric motors or groups

A device for exchanging data between a plurality of rail-supported movable automatic manipulating units for operating a plurality of textile machines with multiple workstations and a common central unit comprises a rail system and a lead system connected to the rail system. The lead system comprises at least two and at most three data-transmitting leads that serve exclusively for data transmission in addition to supply leads for supplying electric current to the automatic manipulating units. The data-transmitting leads form a ring conduit to which the sending and receiving devices of the central unit as well as the sending and receiving devices of the automatic manipulating units are connected via additional sliding contacts. Data are sent from the sending and receiving devices in the form of impulses with a predetermined duration at predetermined intervals and each data impulse is simultaneously guided to two leads with opposite polarity. The sending and receiving devices are furthermore designed such that only such impulses are processed which are simultaneously received via both data-transmitting leads and which have a predetermined minimal signal strength.
