How to wire Otis Elevator buttons to light up when pressed

[Filmed on 2013-06-24.]

Have you ever wanted to wire up newer Otis elevators buttons to light up when they are pressed??? Now you can; just watch this video and find out all you need to know to make your buttons light up. Also shown in this video, is how to install a toggle switch so you can toggle between the button lighting up all the time or only when pressed. It's like having 2 circuits in one.

This video features an Otis concave button with screw terminals. Most buttons use the non-proprietary 4-pin "amp connector". If you have a button with a 4-pin connector, the pins are as follows: (from left to right) negative (-), positive (+), normally open (NO), and normally closed (backwards C).
