Part 1. Installation

CHANGING THE COLOR OF THE PADDLE(OPTIONAL)
This step is optional. Before you start you may want to change the color of the paddle to match your wallplate or decor.
1. Push side tabs in on one side and then the other to release paddle. Lift the cover up and off.
2. Simply put the new paddle onto the switch by side tabs and snap securely into place.Once this step has been completed
please proceed to part 2 wiring.
Air-Gap Switch:
The "air gap switch" will cut power to the device if it's pulled up. It's located right below the main switch itself, often next
to the LED. Pull up for Bulb replacement, push down for normal use.

correctly. Please consult a qualified electrician if necessary. With that said, here are a few other warnings we'd like to point out for your safety:
