CJ Anderson Lever

These are some of the more interesting fixtures I've seen. Instead of a regular push button, these have a lever on the side that you press to activate the switch. These fall under CJA's Water Resistant, Dust Tight, Corrosion Resistant Fixtures. Under the plate, they have the basic CJA black button. This project video shows you the inside of the fixture and how to wire it. A wiring diagram for this button is here.
