Impressive Light Switch With Three Black Wires
Each black white wire set are together.
Light switch with three black wires. If you touch the other black wire with the switch off. Of the three black wires only one of them is hot. This type of switch lets you turn the light off or on from more than one place in the room.
The new switch has a different way to attach. One black wire attached to top screw. All the white wires are capped together and the same is for the ground wires.
And i have no idea how to attach three black wires to two screws. This is a typical wiring setup for a 3 way light switch with black white red and ground wires. Can be found with simple voltmeter its the one that makes the little needle move 2 black wires going to 2 different circuits one to.
This type of switch has two brass screws usually on the bottom and a copper or black screw on the top left. The black and red wires are travelers and are connected to the traveler screw terminals on the two switches. This is what you have 1 black wire is your positive feed.
I have a light switch with three black wires 3 whites which are capped together and the ground attached to box. The cable run linking the two switches is made with 3 wire cable. However the ceiling fan the switch.
I m not sure how to reattach. A three way switch is different. Hi all i am replacing my single pole light switch and noticed when i removed the old switch that there are three black wires coming from the box.
