This will work but only if you only turn it off from one pair of switches. If it is off from the left pair, nothing you do with the right two switches will turn it on. Replacing the two middle switches with DPDT switchs that reverse the traveling wires will make it work from any location.
Pero el salto a los otras llaves d combinación( par opuesto) no es posible si desde su complemento no la habilita. Pero igual está muy interesante el circuito, un abrazo desde Uruguay 🤜🏼🤛🏼
It doesn't work perfectly... if you change the state of 1st or 2nd switch, turning off the light, then the 3th or 4th switch can't control the lamp... In really, the circuit acts a AND logical function, where 1-2 switches are in series with 3-4 switches...
