In acest material este prezentata o solutie minim invaziva, care priveste inlocuirea unui circuit simplu de iluminat, care contine un bec actionat de un intrerupator, cu un circuit de tip CAP SCARA.
Originalitatea solutiei consta in faptul ca se utilizeaza firele anterior existente in circiut, se inlocuieste intrerupataorul cu comutatorul K1 si se adauga, bineinteles, comutatorul K2. In aces caz, in care se mentin alimentarile (cea a comutatorului si cea a becului) in pozitia fizica initiala (in care au fost cand circuitul era simplu) se va vedea ca modul de conectare a conductorilor la borne devine oarecum "exotic".
In this material is presented a minimally invasive solution, which involves replacing a simple lighting circuit, which contains a light bulb operated by a switch, with a two way switching circuit.
The originality of the solution consists in the fact that the wires previously existing in the circuit are used, the simple switch is replaced with the switch K1 and the switch K2 is added, of course. In this case, in which the positions of the supply conductors (that of the switch and that of the bulb) are maintained in the initial physical position (in which they were when the circuit was simple) it will be seen that the way of connecting the conductors to the terminals becomes somewhat "exotic".
