Electric tripping circuit that includes an npn transistor and a pnp transistor in which the base electrodes of the transistors are respectively coupled to one of the other electrodes, ie, collectors of the other transistor, so the circuit can be in two different stable electrical conditions, respectively. They correspond to the two transistors being both conductive or non-conductive characterized because only the base of one of the transistors for example the np-nest transistor resistively coupled to a fixed potential point while its collector is connected to another point of fixed potential through an impedence .
