Wiring Switch Controlled Wall Sockets
Electrical Question: I have a home wall switch wiring problem. I think someone who owned the home before me changed the wiring so that 5 wall sockets are always hot.

This home electrical wiring question came from: Bill , a Handyman from Vallejo, California.

Additional Comments: I’m looking forward to getting a wiring diagram to help me correctly wire this wall switch

Dave’s Reply:
Thanks for your electric wiring question Bill.

Basic Wiring Configuration for Half Hot Switched Outlets

A typical wall socket or receptacle has two outlets, one on the top and one on the bottom, this is also referred to a Duplex Receptacle. A half hot outlet is where one outlet is controlled by a wall switch, and the other outlet is hot all the time. The switched outlet mus have the circuit power source connected to the switch, and then to the switched outlet. The outlet that is not switched has the circuit power connected directly to the outlet.

Wiring Outlets to be Controlled by a Switch

If you want the wall plugs to be controlled by the switch then a wire from the power source must be installed to the switch and then to the outlets.

Wiring Outlets to Not be Controlled by a Switch

If the wall plugs are now controlled by a switch but you would like them to be hot all the time then an additional wire must be installed from the power source to the outlets that you do not wish to be controlled by the wall switch.

Another option is to remove the power wires from the wall switch and splice them together, therefore the switch will be bypassed and the outlets will be hot all the time.
