FIELD: construction. ^ SUBSTANCE: magnetic system comprises a lock cover and an unblocking key device. The lock cover comprises a locking element, a plate element and at least one magnetic pin. The locking element is equipped with at least one tooth that provides for its rotation relative to the plate element. The plate element has at least one tooth for fixation to the locking element. The locking and plate elements have the equal quantity of holes. The magnetic pin is made of two elements of various length and is inserted into the hole of the plate element. The unblocking key device comprises a bracket for its alignment and rotation, a body with holes and at least one coding pin. The coding pins comprise magnetic-sensitive or magnetic-insensitive material and interact with the magnetic pins. Coupled surface of coding pins is placed at the same level with coupled surfaces of the locking and plate elements. ^ EFFECT: due to exclusion of magnetic components from the key body, the magnetic system becomes safe for people with implanted medical devices, which are sensitive to magnetic fields. ^ 11 cl, 4 dwg |
