Often incorrectly called L-Series, this was Haughton and Schindler Haughton's standard fixture line from the mid-1960s until Schindler Haughton was folded in 1989.

There are two types of buttons in this series:

• Type F - "Mushroom" shape (1960s-70s)

• Type H - flat (1970s-80s)

This series was offered with four indicators:

• Metal plate with die-cut numbers

• Segments that look like Type H buttons

• LCD indicators (1980s, see below)

• Projection indicators (1980s, see below)

This fixture has no confirmed name. It is a variant of Type H with metal buttons and light-up numbers. This variant was probably only produced during the Schindler Haughton era (1980s), and is extremely rare, with only a few buildings known to have ever had it.

During the Schindler Haughton era, some elevators with Type H buttons had digital indicators. They are 7-segment negative mode LCD displays, in green, blue, or purple. These indicators are very rare, and are thought to have been made by CE Electronics.
