The switched outlet wiring configurations show two different wiring scenarios which are most commonly used.

The wiring and connections will depend on where the power enters the circuit. The connections for a switched outlet also known as a Half Hot Plug.

The diagram shows the power entering into the circuit at the switch box location, then sending one power line for the outlet which is hot all the time and a switched leg for the top half of the outlet being used for a table lamp or a floor fixture

The Electrical Power Source Enters at the Switch

Outlet Wiring for a Table Lamp or a Floor Light Fixture


These electrical wiring diagrams show typical connections.

The diagram below shows the power entering the circuit at the grounded outlet box location, then sending power up to the switch and a switched leg back down to the outlet.

Notice that these outlets have the tab removed from the "hot" side or Brass side of the outlet which allows the top half of the plug to be controlled only from the switch while the bottom end of the outlet remains "hot" all the time. This is shown in the pictures below.

Switched Outlet Wiring Variations


The switch I am replacing has two red wires plugged into the back and two black wires plugged into the one below. If I want to keep the same set up I can just connect the two red wires to the top brass screw and the two black wires to the bottom but must break the small brass tab between the screws not the plastic, correct? If I don't care to use the wall switch all I have to do is to cap off the red and connect one black wire to one brass screw and one to the other brass screw without removing the brass tab, correct?

From what you have described, I believe that you are correct.
The brass tab can be left in place if you no longer want half of the outlet to be controlled by the switch.

Electrical Tips to Help You Wire it Right

The Safest Way to Test Electrical Devices and Identify Electric Wires!

The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.

The Quickest Way to Check for Faulty Electrical Wiring!

The Plug-In Outlet Tester
This is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect Very handy and easy to use.

Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!

The Wire Stripper and Wire Cutter
My absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires.
This handy tool has multiple uses:
The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets..

The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use.
