These are on an old Otis elevator at a hospital. I think the fire service key, fire service indicator, and the call cancel button were made by Innovation and added later.

Ah so we have an elevator enthusiast here on L-G. Maybe you can answer a question I am curious about. Does the door close button actually function in elevators? I push them almost every time I use an elevator and the doors do not seem to close when I push the button. Every time.

Sometimes it works, sometimes it doesn't. If it has 2 doors, you have to push the right door close button.

Don't be fooLED, T8 IS the worst thing to do to a magnetic T12 fixture.

Ah ok. Maybe some places disconnect it so passengers can't close it on other people wanting to get it.

There were some old 70s vintage elevators (up to code with cables and pullies and brakes and what not) with the old style buttons that would still work and light up. LOVED being around them. They were square style buttons and not the round ones.

The more you hate the LED movement, the stronger it becomes.

The main purpose of the door close button is to work with the independent service function. When enabled (with appropriate key switch), it removes that particular elevator from the call system of the elevator bank (or cancels floor calls in single elevator operation). The car will not respond to any calls other than on the car's panel and remain at that floor with doors open. To register a call, you hold down the floor button and the door close button until the door has closed, and then the elevator will travel to that floor uninterrupted, and the doors will open and stay that way until another call is registered in the same fashion. Independent service can be cancelled with the same key.

In the older elevators (with relay banks), the door close button, I believe, was almost always functional. In electronic, computer controlled installations, it is not always programmed to work in normal service, only in independent service.

What did the buttons look like? Do you have a picture? I could probably identify them if you did.

Door close buttons can have different functions in different elevators or modes of operation. As mentioned before, if the elevator is in IS mode, the door stays open on the floor it's sitting on until the door closed button is pushed (in the case of the last IS elevator I used, it had to be pushed and held until the door closed). In some systems, after boarding, the door closed button will immediately close the doors after boarding. Another common setup, is where the door closed disables the outside call button. In this case, if someone walks up as the door is closing and pushes the button, the elevator would ignore the call button, continue closing the door, and continue to it's destination.

First one: Otis pre Lexan
Second one: Otis square touch buttons (not incandescent, had a special 5 pin touch/neon tube inside)
Third one: Looks European (Don't know the brand)
