True or False: Lines between symbols on ladder diagrams are always vertical and do not cross.

In the context of ladder diagrams, the lines that connect the symbols represent the electrical connections between different components of a control circuit. These lines are not restricted to being vertical, and they can indeed cross each other. The primary purpose of these lines is to illustrate the functional relationships in the circuit, and they can be arranged in various orientations and configurations to simplify the diagram while maintaining clarity.

In many cases, ladder diagrams are designed for readability and to simplify complex circuits, which may necessitate crossing lines to avoid overcrowding in a single vertical or horizontal plane. This flexibility helps in representing the actual wiring and connections as they might appear in real-world applications, where wires may cross without interacting electrically. Thus, the notion that lines are always vertical and do not cross is inaccurate, confirming that the statement is false.
