How to Wire A Switch Receptacle Combo Device
I have I have had many site visitors asking me to put in writing an article on how one can wire a duplex switch and receptacle combination device. While the switch/receptacle combo device is just not common in the house, they’ve several unique applications where they can be very useful!
As with any electrical project, make sure that you take all necessary precautions, most important being to ensure you shut off the power. Always review the safety page on our website.
Another valuable resource available on our site is “The Basics of Household Wiring DVD which can also be available as an instantly downloaded e-book. Follow this link to get your copy.
The switch/receptacle combo device is set up like a duplex receptacle, but has a 15A single-pole switch in a single half, and a single 15A, 125V receptacle in the opposite half. They’ll work along side each other, or they are often connected and used independent of one another.
Here’s a diagram showing the inner function of the switch/receptacle combination device.
Here is an actual picture of a Leviton Switch/Receptacle Combination Device.
I will discuss three different possible scenarios where a switch/receptacle combo device akin to this is able to are available handy.
In your garage or shop, you want to to install a task light, like a florescent light fixture over workbench. However, the walls are all finished so getting a brand new wire to a switch and then up to the sunshine shouldn’t be that easy. However, you could have a receptacle just above the bench that you may get your power source from.
You may change this duplex receptacle to a switch/receptacle combination in order that you still have power within the outlet, but can use the switch to regulate your new overhead task light. Fishing in a wire from the receptacle to the light fixture is fairly easy, so that is how you would wire the switch/receptacle combo device in this case.
A typical example of this case is in case you had the same scenario as above, but with a 3-wire circuit, resembling in a kitchen split receptacle, and wanting so as to add some under-counter lighting for instance.
Just because the receptacle that you just replaced can have the tab on the hot side removed, here we must remove the tab on the device as well. This can put the sunshine on a special circuit as the receptacle, but again offers you the specified results of a usable receptacle, and a switched light fixture with no difficult wiring renovation.
Understand that this isn’t the best situation, as you now lose the required amount of circuits in the kitchen. However it’s an example of how we will have the switch and receptacle operating independently from one another on different circuits.
Here is a situation where your required result is a receptacle controlled by the switch in the mix device.
Let’s say you might have a task light on your shop, and it’s cord connected and designed to be mounted over your work area and then just plugged in to an outlet. Instead of plugging the sunshine in and out every time you want to control the sunshine, it will allow you to maintain it plugged in and use the switch for control.
