What are short lengths of conductors on the program card referred to as?

Short lengths of conductors on a program card are referred to as jumpers. This term is used to describe the pieces of wire that connect two points on a circuit board or card, effectively allowing electrical signals to bypass other components or connections. Jumpers can be especially crucial for configuring settings or connecting various sections of a circuit in a traffic signal system.

In the context of traffic signal technology, jumpers are often used to set specific functions or to connect different functionalities within signal control equipment. Understanding the role of jumpers helps technicians manage and troubleshoot signal systems effectively, ensuring the connections are made correctly for optimal performance. This foundational knowledge of circuit design and wiring is essential for Traffic Signal Technicians looking to maintain and repair complex traffic control systems.
