What is the purpose of the ignition safety switch on a PWC?

The ignition safety switch on a Personal Watercraft (PWC) is designed to enhance safety by attaching the operator to the craft. The switch typically connects to a lanyard that the operator wears, ensuring that if they fall off or are thrown from the vessel, the lanyard pulls the ignition safety switch, cutting off the engine immediately. This action prevents the PWC from becoming an uncontrolled hazard, reducing the risk of injury to the operator and others in the vicinity. This safety feature is crucial for preventing accidents, as it enables the operator to maintain control and minimizes the chances of the craft continuing to operate without them.
