Introduction: I chose this topic; because I thought it would be fun to make a four-way switch that turns on the same light. I got the idea to make one when I went online to search for the perfect project idea. I found information about a three way light switch and decided that this is what I want to do, but to make it more difficult I decided to create a four way light switch instead. It sounds like the perfect experiment to try. I felt that if I did this project I would learn more about electricity and the way it works. What is a four way light switch? A four way light switch is an electric switch that uses electricity to power a light bulb that can be turned on by four different places and not just one or two. The great thing about a four way light switch is that there can be more then one way to turn on one single light. In order to achieve the perfect four ways light switch the four-way switch must be in the center of two three light way switches in order for the whole p roses to work. A hot wire or wire of 120 volts will connect from a battery to the light bulb. A wire that is neutral will also be connected from the battery to the light bulb. The third wire can’t be neutral or 120 volts (hot wire) and will just float near the 120-volt wire. The third wire that is neither neutral or 120 volts, and 120 volt wire will connect when the switches are turned on and will produce the light. When the light will be turned on the switches should be one circuit in order for the light bulb to turn on and the electrons to travel through the circuit. The switches must be either up or down at the same time in order for the electricity to flow. If one of the switches is up and the other is down the light will not work. If one o... ...ire. When the switch in the center of the hot wire is crossed it must touch both the blue and hot wire. To make the cross switch work you must make sure that when you cross the switch in the center of the hot wire and cross the switch in the center of the blue wire that they both are touching both wires, only then will the four-way switch work. The switches must be made in a way that they make a complete circuit. The electric cells in the battery will cause the electrons to then travel from the negatively charged electricity to power the light. Once it has touched the filament witch is a metal it will conduct electricity. The melting point of 6,580 degrees F happens inside the light bulb when it is turned on. The electricity then continues to travel through the neutral wire so that the energy can go back to the power source or battery and complete the circuit.
