Long Square Call Button

These are some exclusive fixtures used on newer Long elevators that are only found on Long elevators. The style of them is similar to fixtures made by Innovation and Adams, but this button is actually made by Monitor (just like their other buttons).

This video shows the back side of the buttons and compares them to similar fixtures. The wiring for these is just like any other Monitor fixture, except Long had a custom LED board for the light. I modified the light board to work with a lower input voltage, but you can also use a standard lamp socket with PSB bulbs.
