For the safety switch system in electrically-driven equipment, what is required for operation?

The operation of a safety switch system in electrically-driven equipment often requires a physical interaction from the user to ensure that the equipment can be safely engaged or operated. In this case, a footswitch being depressed serves as a direct means for the operator to indicate readiness to use the equipment while ensuring that both hands remain free for other tasks. This is particularly important in environments where an operator's hands need to be unobstructed to control the equipment safely.

Footswitches are designed to provide a hands-free option to control power and can also be configured as a safety interlock, which ensures that the operator is in a safe position before the equipment operates. This design promotes safety and minimizes the risk of accidents while working with electrically driven machinery.

While other options may represent necessary components or conditions for operation, they do not specifically emphasize user interaction through a footswitch, which is often critical for ensuring safety standards in operational settings.
