SWITCH STAIRCASE OR COMMUTATION

This project will use a 220VAC 60HZ light bulb as a toggle switch turning a 220VAC 60HZ light bulb on and off from several different points.

Here we see the schematic diagram with all its values ​​and electronic components

Before carrying out a professional PCB we will have to simulate our circuit in the PROTEUS8.8 software for this we will use the brain of this circuit which is the integrated NE555 this is a multivibrator circuit.

The present project is based on the electrical switching system of 2 more points. Next, we will describe the electrical switching circuit. In an electrical installation, a switch is an electrical or electronic device that allows modifying the path that the electrons must follow. They resemble switches in their outward form, but switches, once they break one circuit, immediately make another.

This electronic circuit is the same as an electrical switching system where we can control, in this case, from 3 different points. This electronic circuit also allows us to save on expenses since an electrical switching system has a higher cost.

With the pushbuttons we will send a signal to the CINE555, it receives the signal and will activate the MOC and also the TRIACBT136 and will activate a 220VAC light bulb. And to turn it off we will have to press any of the 3 pushbuttons. This circuit can also be expanded from 5 to 10 inputs. Max inputs to control an AC light bulb.

And after the tests we will see that the operation is the same as an electrical switching circuit.

Once the circuit has been simulated and we see that it worked and everything is fine, we will enter EasyEDa to design our circuit and PCB, as we can see there in the images, we will see the circuit design, schematic design of the PCB tracks and finally the 3D design of how our PCB will be seen.

This software is very professional and has all the components that we will use for the creation of the PCB.
