<p>The present invention relates to an electrically actuated lock of the type comprising a rotor pivoting in a body and capable of being locked in relation to the said body by locking members constituted by pairs of opposed pistons or by keepers. The locking members are displaced by notches of a key, coded to permit the rotation of the rotor by action upon the key head. In this invention the unlocking of the rotor is effected by electric means without any opening of the rotor to the external environment, thus ensuring perfect sealing and inviolability. The lock comprises a key shank provided with coded notches, the shank being connected in translation with the movable armature of an electro-magnet, the rotor being provided with a graspable head by means of which the user can rotate the rotor when unlocked by the key.</p> |
