Why do you want to replace it? You describe it as working properly.

If you are looking for the receptacle that it's supposed to control, the problem is at the receptacle. Look for the one with a red insulated wire connected to one gold screw and a black insulated wire connected to the other gold screw. Then break off the tab that connects the two screw plates and the switch will control that half of the receptacle.

If it's another problem, please post back with details.

BTW, that's 14 gauge wire so the circuit must be limited to 15 amps.

Also, I avoid using back-stab devices such as that switch due to their inherent tendency to fail, but that's another story.

All receptacles work even when the switch is off so they aren’t part of this.

Did you check both plug-ins on each receptacle? Because of this:

Per HU-17865...: Then break off the tab that connects the two screw plates and the switch will control that half of the receptacle.

It is unclear what your problem is. Do you just want to replace the switch or do you want to control the receptacles with a switch?

If you want to just replace the switch (which is what you seem to be asking), put the red wire to one screw on the new switch and the two black wires to the other screw of the new switch. Done.

We painted my daughters room and installed new trim. All receptacles and the light switch were an old almond color and I replace everything else with white. Both outlets on every receptacle work even with the light switch off.

So what is your question? Do you want to replace the light switch?

Yes I’d like to replace the switch

If you want to just replace the switch, put the red wire to one screw on the new switch and the two black wires to the other screw of the new switch. Done.

Ok thanks. I assumed that was the way to go but I wasn’t sure.
