What component is used to change the direction of a control cable?

The component used to change the direction of a control cable is the pulley. Pulleys are designed to guide and redirect the cable along a desired path, allowing for more efficient mechanical movement and control. They allow for smooth operation by reducing friction and facilitating the routing of the cable in systems, such as those found in aircraft control systems, where changing the direction of cables is essential for proper functioning.

Levers, while useful for amplifying force and changing the angle of application, do not primarily serve the purpose of directing cables. Rings can be used in various applications but are typically not aimed specifically at changing cable direction. Screws are fasteners and do not have a role in manipulating the path of a control cable. Thus, pulleys are the most effective and common solution for this specific function in rigging and assembly scenarios.
