Abstract

Anti-theft device of special application to automobiles characterized in that the high-voltage transformer coil of the automobiles is enclosed in a safety box, the inlet and outlet of current through the walls of said box in which there are holes for the cooling of the coil; in such a way that for the current to be transmitted to the coil, it must pass through a lock switch or any other simple switch system, the current being cut or linked from it in four points more or less whose points are indicated by letters since they are rotary switches that have twenty-four positions more or less corresponding to each position of a letter or figure; it being provided that each rotary switch is formed by a manipulator; a disc that bears the letters or figures; an axis in which the whole assembly of each switch is mounted, which is provided with as many grooves as there are positions; an insulating wheel diametrically crossed by a passage of current or contact provided with as many projections as there are letters which contacts fix the positions by means of the action of a spring that also serves for the passage of current from one switch to another; the insulating disc described being mounted which rolls by effect of the position of a spring so as to allow the change of the combination since with the separation of a slide the shaft retracts free from the grooves to rotate freely to the desired position in the that the pressure of the spring brings the disc back into the selected position.
