I installed a linear actuator in the attic. By using this wireless remote I didn't have to install a wall switch. This way the installation was much easier - no wires going into the house. The remotes have handy UP/DOWN buttons that do what they say. Very easy to install between 12V power supply and linear actuator. I'm an EE so I went ahead and complicated the installation using a 2 channel relay and some LEDs. However, these additions were not required for basic functionality.
