Abstract

Magnetic-electronic key card, applied to a lock, especially characterized in that the code, contained inside a key, is transmitted to an electronic circuit as the key is introduced into the passage or female, the code being formed by the association of at least two series of plates, of, material with properties of temporary magnetization, non-permanent, such as sweet iron, which does not contain practically carbon, and with antioxidant protection and which are capable of diverting and absorbing the flow lines of magnetic field, modifying the state of at least two magnetic detectors, such as the reed contacts and the hall effects, interposing between the magnetic detectors and a permanent magnet, both located inside the passage, and so on. Is introducing the key, the two series of plates of sweet iron send signals by means of a multicable, sufficiently far from the passage, one of them to a cash electronic clock and the other series of plates to a shift register, reading the code formed by the series of plates that make up the code, with the lights of a few luminescent diodes, and inserting a comparator that analyzes the signals of the code with respect to the program established by means of microswitches and, from the result of the comparison, the electronic circuit, thus formed, allows the current to be opened, for the opening of the locking/unlocking mechanisms of the lock, in the case of coincidence between the code entered with the key and the programmed with the microswitches, this programming being done when the key was first introduced and the code was read with the lights of the luminescent diodes or simply without reading and memorizing the code by means of a memory chip and a push button.
