Sparkfun support will be closed from 3:00PM to 4:15PM on April 27th for a company-wide townhall meeting. We will resume regular hours on the 28th.
Description: Want to control a standard wall outlet device with your micro controller, but don’t want to mess with the high voltage wiring? This might just be the right device for you!
The PowerSwitch Tail II is designed to allow you to safely control an outlet device without exposing any 120VAC voltages. You can plug in any standard 120VAC 3-prong outlet to be controlled by most any microcontroller. This will work great with Arduino! The PowerSwitch Tail II improves on the original PowerSwitch Tail by allowing you to switch a bigger load (now up to 15A) with a wider range of control signals (3-12VDC). The PowerSwitch Tail II can be setup for normally open or normally closed operation by changing a jumper inside the unit with the default set as open.

Was looking to tinker with some control lights in my office with an Arduino, and didn’t want exposed wiring or the hassle of the containment of it. This may be a little pricey up front, but will definitely be ordering more in the near future. Pro tip that helped me out: Use a set of old Cat 5e wire and split the wires to get a nice cord you can use for this and run a distance if needed.
This was very easy to use and will make doing an IoT primer class pretty trivial.
Anyone know how to hack these things so I can get the power to run a Sparkfun Thing Dev from the Tail itself rather than needing an additional power outlet to power the Thing?
There’s really not a good way to hack this to split out a pre-relay DC converter. But since it is really just a relay in a fancy housing, you could create one on your own with something like our beefcake relay.
Had a huge project for school and needed a couple of these to program to power some key components. Best programming purchase I’ve made thus far.
I wanted to use my Arduino Uno to control the temperature in different molds that I have for creating carbon fiber parts. I know that with a few hours work, and a few dollars, I should be a able to make a relay based system for switching the heater (in this case a 250 Watt bulb). But, for the modest extra cost of the Power Switch Tail, I saved my self at least an afternoon and possibly an injury. It does what is says, appears robust, and I am happy that I purchased it.
I use it to turn on the amps and speakers when my projector is on. Saves me from having to go switch them on each time i want to watch something.
I would recommend the Beefcake Relay instead.
