These fixtures were used Haughton's later installs. I've worked on both call buttons and on an entire car panel.
In this video, I show a detailed look at these fixtures and then wire it up. I call these "L series" in the video, but these are actually type H.
This is an old Haughton car panel that came from a parking garage. In this project, I clean the panel up and wire it up.
Why Schindler Haughton? Well, that's because this particular piece was installed during Haughton and Schindler's merge. During that time, these buttons were still being installed. In this project, I clean up the panel, and wire it up.
