What is an ignition safety switch lanyard on a pwc?

An ignition safety switch lanyard on a personal watercraft (PWC) is a safety device designed to prevent the vehicle from operating if the rider falls off or is ejected. The lanyard is typically attached to the rider's wrist or life jacket and connects to the ignition switch. If the rider is thrown from the PWC, the lanyard pulls free, shutting off the engine and helping to prevent accidents or collisions. This feature enhances rider safety by ensuring the PWC cannot be operated without the rider present.
