Electronic anti-theft alarm device, which is composed of a general electronic circular system that is characterized by basically consists of three stages of timing that get voltage when closing the first two sections of a multiple switch (a and b of s1) driving a transistor of the type -pnp- (tr 1) and when a switch is closed that is activated when a door is opened, the previous one has become a conductor and gives voltage to a semiconductor-rectifier diode (scr 1) that drives the first timer integrated by a potentiometer, a resistor, a capacitor, a zener diode and a transistor of the same type (p1, r6, c1, dz1 and tr2) and the latter, after a pre-established time, becomes conductive also doing it with another diode ( scr 2) so that this timing stage allows leaving the vehicle or home without triggering the alarm.
