Adams is a supplier of elevator and escalator parts. My video in particular focuses on Adam's "Survivor" button which is a common style of button used. These fixtures are easy to wire up and work with, making it an ideal fixture for enthusiasts who don't know a lot about wiring.
This is an interesting Adams replacement panel for what my guess was an Otis elevator. It's a tall and narrow panel and only has two floors. For this project, I cleaned up the panel, and wired up most of the buttons to light up when pressed.
As stated before, these buttons are very easy to wire up as you don't need a lot of materials to do a solid wiring job. My video shows you wiring multiple types of Adams buttons (though they have the same base).
