A friction switch coupling for torque transmission from a rotor which can be driven about an axis to an element to be driven, including a friction disk clutch with an electromagnet arrangement which includes a coil body and a ferromagnetically conductive coil carrier supporting and at least partly surrounding the coil body, which the carrier has a web segment lying radially outermost in relation to the coil body and oriented parallel to the axis, and an inner web segment, and between the inner and outer web segments of the coil carrier are provided permanent magnet means via which an axially movable friction segment of the friction switch coupling can be connected magnetically with the rotor, so that when the electromagnet arrangement is in electrically connected state, by weakening of the magnetic attraction effect of the permanent magnet means, the contact of the friction segment on the rotor can be eliminated.
