摘要： A locking and control device has at least one tumbler in which a control magnet is arranged, and which is rotatable between two extreme positions. The tumbler is movable by means of an operating magnet carried by a functional member to an operative position in which a protection bolt can be inserted through an excision of the tumbler. A magnetic compensatory device comprises a further magnet carried by the functional member, with the compensatory magnet and the operating magnet arranged so that in the operative position they are located on either side of the control magnet but in a plane transposed along the axis of rotation of the tumbler. The compensatory device exerts a repulsive force contrary to the operating magnet, with the result that the control magnet is urged to said operative position which is intermediate said extreme positions. In a non-operative position the tumbler has a contacting surface disposed adjacent a contacting surface of the bolt, to prevent withdrawal of the latter, and the contacting surface of the tumbler is formed with at least one detent groove. The bolt can enter into detent engagement with said groove to prevent unauthorised rotation of the tumbler when in a position separate from the operative position, and the tumbler is associated with a security-type magnet arrangement which tends to shift the tumbler into the position of detent engagement.
