A system (10) utilizing a switch (16) to prevent injuries due to marine engines (22) such as propellers (24) striking swimmers and carbon monoxide asphyxiation to persons next to a boat. The switch (16) is normally in a closed position and is only opened when a movable element such as a ladder or gate (32) on the boat travels to an unlatched position. Such movement interrupts the ignition circuit (20) of the boat engine. An override device (28) is also employed to allow normal operation of the marine engine and requires both mechanical and electrical interconnection or matting of connector elements (48).

L'invention concerne un système (10) utilisant un commutateur (16) pour empêcher des blessures provoquées par un moteur marin (22), par exemple pour empêcher des hélices (24) de venir frapper des nageurs ou le monoxyde de carbone d'asphyxier des personnes se trouvant à proximité d'un bateau. Le commutateur (16) se trouve normalement en position fermée et n'est ouvert que quand un élément mobile tel qu'une échelle ou une porte (32) se trouvant sur le bateau se déplace pour prendre la position non verrouillée. Un tel déplacement interrompt le circuit d'allumage (20) du moteur du bateau. Un dispositif de priorité (28) est également employé pour permettre le fonctionnement normal du moteur marin et nécessite une interconnexion ou un accouplement de connecteurs (48) à la fois mécanique et électrique.
