In a bedroom a “friend“ removed the light switch. I have no idea if it was a single or double. There are 3 cables coming into box with 3 wires each, black, white and copper. One of the black is constant hot. I have read many articles looking to put in a single pole ( or double) pole light switch and I am so confused. Could you “dumb down” an answer for me. There are 3 outlets and an overhead light, 2 of the outlets work. Thank you for any info you can give me.
If you are sure that there is only 1 (one) always hot black wire, then follow these steps:
- Turn off power at the breaker.
- Connect all of the ground wires together with a wirenut and stuff them in to the box.
- Connect all of the white wires together with a wirenut and stuff them in to the box.
- Get yourself a 6 inch piece of black wire and strip the ends. You've just made yourself a pigtail. Match the gauge of this wire (12 or 14) to the gauge of the wire already in the box. Connect one end to the switch.
- Connect the other end of the pigtail to the always hot black wire and one of the other black wires with a wirenut.
- Connect the remaining black wire to the switch.
- Install the switch and cover.
- Turn on the breaker.
- Turn the switch on and off. If it controls the light, you are done.
- If the switch doesn't control the light, turn the breaker off and repeat from step 5 but swap the two black wires that are not always hot.
