A control device for a magnetic cylindrical lock includes a tubular housing eventually having on its inner surface axial and circumferential grooves, a cylindrical plug rotatable in the housing about a central axis and defining a central key channel and at least one axial recess on its cylindrical surface, a plurality of magnetic rotors supported in the plug for rotation about an axis transverse to the center axis of the plug, one face of the magnetic rotors having a third recess alignable with the second recess, a sleeve arranged for rotation and for an axial displacement between the housing and the plug, and arresting elements projecting from the sleeve to cooperate with the recesses in the housing, in the plug, and in the magnetic rotary members.

Control device particularly for use in a lock

The control device for cylindrical locks includes a housing having on its inner surface longitudinal and annular guiding recesses, a cylindrical plug or core rotatable in the housing about its center axis and defining on its surface second recesses, at least one magnetic rotor supported in the plug for rotation about an axis transverse to the center axis and defining a third recess alignable with the second recess, control strap arranged for axial displacement on the plug and being rotatable therewith, and arresting elements projecting from the strap into the first and second recesses and being axially displaceable with the strap into engagement with the third recess in the rotary member when this third recess is in alignment with the second recess.
