My friends from the CADERNO DO TÉCNICO channel, for this video prepared especially for you, who follow us in these tasks, we would like to thank you very much for your participation and support. Welcome to all, electricians, technicians, engineers and lovers of the technology sector, subscribers and admirers of this channel. Continuing with these practically primary installations, today on the channel we have the diagram of a control for three simple switches, which will individually activate each of the lamps (L1, L2, L3) by the switches (S1, S2, S3). We can say that the difference between this task and the one previously performed with two simple switches is only the addition of a third simple switch, powered by the same phase. Once all the switches receive the phase from the single-pole circuit breaker that protects the lighting circuit, we can connect a return from each switch to each lamp (L1, L2, L3), taking these returns to the lamp receptacles. After connecting the returns, all that remains is to connect the neutrals to each lamp to complete the two wires that go to the receptacles. We emphasize that, when we use a simple switch, we only have the condition of lighting at a single point of the installation. Our network is derived from a standard with a supply of 127 volts (with PHASE and NEUTRAL). I thank you for your time and that's it. See you in the next video on the channel. I am your friend and instructor of the channel, CADERNO DO TÉCNICO.
