摘要

Central electronic intermitters for automobiles (certificate of addition of the main patent number 509.438) includes a circuit of protection against short circuits, formed by a transistor (16), a divider of tensions composed by two resistances (27, 28), a diode (15), and a resistance of charge of the collector (16). In normal conditions the base tension produced by the tension divider (27, 28) is of such magnitude that the transistor (16) is saturated, whereas the diode (15) is completely locked and the protection circuit is inoperating .
