As you can see in the picture the top switch doesn’t work at all. The bottom switch is the one that actually works.
How can I change this 2 switches to just 1 - when I would buy a brand new one
Please help on this!!!
Assuming that the black and red wires that are connected to the same side of the switch power either light fixtures or standard outlets...
Since that is a duplex switch it performs 2 functions or handles 2 lighting circuits. If you want both functions to be controlled from 1 switch just combine the 2 wires going out of the switch. A picture of the other side of the switch is necessary to see how the whole circuit is wired.
