Switch system for preventing marine propeller injuries
First Claim
1. A safety system for a boat having a motor driving propeller including an element movable between a latched and an unlatched position for gaining access to the boat, and an ignition circuit for the motor,comprising:
- a. a switch in series in the ignition circuit normally in a closed position, said switch being opened when the movable element is opened to the unlatched position, said switch interrupting the ignition circuit;
b. an override device for said switch, said override device including first connector means and second connector means, said first and second connector means normally being mechanically electrically connected by manual mating to activate said switch associated with said movable element to permit the ignition circuit to start the motor, said first and second connector means further permitting the ignition circuit to start the motor when said first and second connector means are mechanically and electrically disconnected, by interrupting said manual mating and are mechanically and electrically configured to complete the ignition circuit without said operation of switch.

Abstract
A system to prevent injuries due to marine propellers striking swimmers and other persons in the water next to a boat utilizing a switch. The switch is normally in a closed position and is only opened when a movable element such as a ladder, gate, and the like on the boat travels to an unlatched position. Such movement interrupts the ignition circuit of the boat motor. An override device is also employed to allow normal operation of the marine engine and requires both mechanical and electrical interconnection or matting of connector elements.
