How to Wire Half-Hot Plugs and Switched Outlets

Question: I have a switch in a bedroom w/three outlets which does not seem to have a purpose.

• Top and bottom plugs on all three outlets are hot with the switch in on or off position.
• The top and bottom plugs all remained hot even after disconnecting the Red and Black wires from the switch.
• Additionally, the Red and Black wires at the switch tested hot after being removed from the switch. Ultimately, my goal is to have top plug to be switched and bottom to be live.

Any thoughts would help.
Thank-you.

Electrical Wiring Half-Hot Plugs and Switched Outlets

• Keith, if the bedroom does not have a ceiling light fixture then the switch was wired to control at leas one outlet in the room but the wiring has been altered to make the outlets hot all the time.
• The outlets will need to be examined to identify the wiring that runs to the wall switch and then make the appropriate adjustment.
• The links below will lead to wiring diagrams that show how switched outlets are wired.
