Light switches with integral plug-in outlets are available at most hardware stores, including The Home Depot and Lowe's. There are a wide variety of switches available, so it is important to consider the requirements of application before making a purchase.
Installing an outlet with an integral light switch can be more difficult than wiring a standard plug. Homeowners must understand the electrical layout of the device before attempting installation. When working with electricity, always follow safety precautions, including cutting off power at the circuit breaker panel or the house main shutoff. When in doubt, always consult a local licensed electrician.
