1. An electromagnetic clutch, comprising:
a shifting sleeve which is arranged on a shaft for joint rotation therewith and is linearly displaceable along the shaft between a first engaged position, a second engaged position and a disengaged position located between the engaged positions,
a first clutch body and a second clutch body, which are axially spaced apart from each other and are each aligned coaxially with the shaft, each clutch body having an internal toothing, and
a stator having a first and a second energizable coil for direct or indirect adjustment of the shifting sleeve along the shaft,
the shifting sleeve having a first toothing for engaging the internal toothing of the first clutch body in the first engaged position and a second toothing for engaging the internal toothing of the second clutch body in the second engaged position, and
a locking device which prevents the shifting sleeve from moving beyond the disengaged position in the direction of the further engaged position when the shifting sleeve is displaced out of an engaged position in the direction of the disengaged position.
