Abstract

Timed electronic lock, of the type comprising electronic means interconnected with combination or opening code, presenting a set of semi-conductors, such as; thyristors, transistors, diodes and electroluminescent diodes interconnected through resistors, capacitors and pushbuttons that in turn connect on relays, characterized in that said lock comprises a capacitor that is charged through a pushbutton and a resistor and discharged through preprogrammed resistors, and whose capacitor directly biases two transistors which in turn positively polarize a circuit constituted by a series of triprable thyristors, one successively to the other after the previous trip in the direction away from the positive voltage; there are the two transistors, which at the end of the series activate another transistor that excites a relay which gives an opening order to the locks of the lock, which comprises a second relay that is permanently activated and that protects from the violation and gives warning orders by closing the circuit in case of occurrence, activates the general alarm circuit when another button is pressed, and because the box containing the circuit is placed, it transfers the command to the general alarm unit, signaling in a luminous way the activation of each one of the three relays.
