Light switch wiring diagram ground 3 - diagram never used one so i m not sure i figure it out like this take an ohm meter find two terminals that have resistance then don t have resistance when the key switch is turned from off to the first click summary easy to understand light switch wiring fully explained light switch wiring with diagrams and pictures with step by step instructions to guide you with the power ing to the switch and then going to the lights you will notice that there are two black wires two white wires and two ground wires bare wires option 3 fixture between two three way switches power through switch light is controlled by two three way switches with the light between the switches and the power first going through a switch then to the light and onto the second three way switch span class news dt 29 03 2019 span nbsp 0183 32 a 3 way light switch allows you to control a light source from two separate points although.
a 3 way is one of the hardest electrical circuits to figure out it s also one of the most useful how to wire a 3 way switch wiring a 3 way switch is a little more tricky than wiring a 2 way switch first of all we need to go over a little basic terminology on switches just cut the switch off and there s 3 wires the white is hot blue is to the bar black is ground i didn t use a switch that was lit up so no need for ground just white and blue 3 way switch wiring diagram line to light fixture line voltage enters the light fixture outlet box no longer allowed after 2011 nec if no neutral wire in switch boxes three way switch wiring requires the use of a three conductor cable to connect the two switches the red wire in the cable is known as the traveler and it connects to the black terminal screws on the pair of switches wiring a three way circuit is sometimes easier if you have a diagram.
