Ladder diagrams are specialized schematics commonly used to document industrial control logic systems. They are called “ladder” diagrams because they resemble a ladder, with two vertical rails (supply power) and as many “rungs” (horizontal lines) as there are control circuits to represent.

https://en.wikipedia.org/wiki/Ladder_logicLadder logic was originally a written method to document the design and construction of relay racks as used in manufacturing and process control. Each device in the relay rack would be represented by a symbol on the ladder diagram with connections between those devices shown.

gyan.fragnel.ac.in/~dileep/Ladder.pdfIf we wanted to draw a simple ladder diagram showing a lamp that is controlled
by a hand switch, it would look like this: The "L1" and "L2" designations refer to
the two poles of a 120 VAC supply, unless otherwise noted. L1 is the "hot"
conductor, and L2 is the grounded ("neutral") conductor. These designations
have nothing ...
