There are 3 standard types of light switches. The first is an easy, solitary light button.
The simplest means for three-way switches is to place the light in between the two switches. You need to look closely at an electrical wiring diagram to comprehend.
The cord needs to be 12.2 Romex right up to the first button, then run 12.3 Romex to the light and afterwards on to the second button. The 12.3 Romex has an additional wire called a traveler (typically red), which is needed for 3-way switches.
At the first button, the 12.2 Romex from the circuit run goes into all-time low of the button box as well as the hot (black) cord links to the bottom right terminal on the button.
The 12.3 Romex goes into via the top of the button box. The hot traveler (red) wire links to leading left terminal on the button. The black (hot) wire links to the leading right terminal on the button.
The 12.3 neutral (white) wire links straight to the 12.2 neutral wire with wire nuts as well as the copper ground wires are also attached along with wire nuts. At the light box, you ought to have 2 ends of 12.3 Romex hanging out. One end comes from the first button the various other end comes from the second button.
Connect the copper ground wires with each other with a cord nut to obtain them out of the means, as well as then link the 2 red traveler wires with each other with a cord nut.
Currently find the black wire coming from the first box as well as the white wire coming from the second box as well as link them with each other with wire nuts. It is usual practice for 3 as well as 4-way switches.
Currently, at the second button, you will link the red traveler wire to the leading left terminal. The white, wire currently labeled as black with tape, links to the upper right terminal. The black wire will link to the lower right terminal screw. The copper wire will link to package if it's a steel box or the green ground screw on the button if package is plastic.
The light box ought to currently have a black wire as well as a white wire sticking out which is just what you will should link the light to. The hot traveler (red) wire links to leading left terminal on the button. The black (hot) wire links to the leading right terminal on the button.
Currently, at the second button, you will link the red traveler wire to the leading left terminal. The copper wire will link to the box if it's a steel box or the green ground screw on the button if the box is plastic.
